OEM level 1 charger WTB

My naughty 4 y.o. daughter decided to swing like a monkey from the charger while it was sticking out of charging port and snapped it. Luckily no injury but the charger adapter is toast. The car itself (including charging port) is fine. Anyway, if you want to get rid of your OEM level 1 for a reasonable price, send me a message I am not ready to upgrade to a level 2 yet Thanks

Charging System - Volt Meter Fluctuation Information



INFORMATION



Bulletin No.: 07-06-03-009B



Date: February 05, 2010



Subject: Information on Voltmeter Gauge Fluctuation Due to Regulated Voltage Control System and Concerns About Camper/Trailer Battery



Charging



Models:



2005-2010 Cadillac Escalade Models



2005-2010 Chevrolet Avalanche, Silverado, Silverado Classic, Suburban, Tahoe



2005-2010 GMC Sierra, Sierra Classic, Yukon Models



Supercede:



This bulletin is being revised to add the 2010 model year. Please discard Corporate Bulletin Number 07-06-03-009A (Section 06 -



Engine/Propulsion System).



Voltmeter Fluctuation Condition



Some customers may comment that the voltmeter is fluctuating between 12 and 14 volts on their full size pickup or utility vehicle. Starting with the



2005 model year, light duty full size pickups and utilities are equipped with a Regulated Voltage Control (RVC) system. This system reduces the



targeted output of the generator to 12.6-13.1 volts when in "Fuel Economy Mode" to improve fuel economy. The generator may exit "Fuel



Economy Mode" if additional voltage is required. This will cause the voltmeter to fluctuate between 12 and 14 volts as opposed to non-regulated



systems that usually maintain a more consistent reading of 14 volts. This fluctuation with the RVC system is normal system operation and NO



repairs should be attempted.



Camper/Trailer Battery Charging Concerns



Some customers may comment that when towing or hauling a camper/trailer, the auxiliary battery for the camper/trailer will not stay charged. In



most cases, this concern is blamed on the new RVC system. While the RVC system does reduce the generator's targeted output voltage to 12.6-13.1



volts when in "Fuel Economy Mode", this feature is bypassed if the tow/haul feature is enabled. With the tow/haul feature enabled, the RVC system



will stay in "Charge Mode" and the targeted generator output voltage will be 13.9-15.5 volts, depending on the battery state of charge and the



estimated battery temperature. To keep the generator in the "Charge Mode", use either of the following two methods.



- The first method is to use the tow/haul mode when towing or hauling a camper or trailer.



- The second method is to turn on the headlights, which will increase the generator's targeted output voltage to 13.9-14.5 volts.

Corporate Bulletin Number 11-00-90-001 (Section 00 - General Information).



GM dexos 1(TM) Information Center Website



Refer to the following General Motors website for dexos 1(TM) information about the different licensed brands that are currently available:



http://www.gmdexos.com



GM dexos 1(TM) Engine Oil Trademark and Icons



The dexos(TM) specification and trademarks are exclusive to General Motors, LLC.



Only those oils displaying the dexos(TM) trademark and icon on the front label meet the demanding performance requirements and stringent



quality standards set forth in the dexos(TM) specification.



2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 346



Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 1(TM) engine oil.



GM dexos 1(TM) Engine Oil Specification



Important



General Motors dexos 1(TM) engine oil specification replaces the previous General Motors specifications GM6094M, GM4718M and



GM-LL-A-025 for most GM gasoline engines. The oil specified for use in GM passenger cars and trucks, PRIOR to the 2011 model year



remains acceptable for those previous vehicles. However, dexos 1(TM) is backward compatible and can be used in those older vehicles.



In North America, starting with the 2011 model year, GM introduced dexos 1(TM) certified engine oil as a factory fill and service fill for gasoline



engines. The reasons for the new engine oil specification are as follows:



- To meet environmental goals such as increasing fuel efficiency and reducing engine emissions.



- To promote long engine life.



- To minimize the number of engine oil changes in order to help meet the goal of lessening the industry's overall dependence on crude oil.



dexos 1(TM) is a GM-developed engine oil specification that has been designed to provide the following benefits:



- Further improve fuel economy, to meet future corporate average fuel economy (CAFE) requirements and fuel economy retention by allowing



the oil to maintain its fuel economy benefits throughout the life of the oil.



- More robust formulations for added engine protection and aeration performance.



- Support the GM Oil Life System, thereby minimizing the replacement of engine oil, before its life has been depleted.



- Reduce the duplication of requirements for a large number of internal GM engine oil specifications.



Corvette Engines Built at Wixom That Require the Use of Mobil 1(TM) Oil



The following Corvette engines built at Wixom, Michigan are equipped with an OEM oil fill cap that identifies Mobil 1(R) SAE 5W-30 as the



engine oil that is required to be used in these engines.



- Corvette Engines Built at Wixom - RPO LS7 and LS9 for the Z06 and ZR1



- Corvette Engine Built at Wixom - RPO LS3 for the Grand Sport Coupe with Manual Transmission



International Lubricants Standardization and Approval Committee (ILSAC)



GF-5 Standard



In addition to GM dexos 1(TM) a new International Lubricants Standardization and Approval Committee (ILSAC) standard called GF-5, was



introduced in October 2010.



- There will be a corresponding API category, called: SN Resource Conserving. The current GF-4 standard was put in place in 2004 and



became obsolete in October 2011. Similar to dexos 1(TM) the GF-5 standard will use a new fuel economy test, Sequence VID, which



demands a statistically significant increase in fuel economy versus the Sequence VIB test that was used for GF-4.



- It is expected that all dexos 1(TM) approved oils will be capable of meeting the GF-5 standard. However, not all GF-5 engine oils will be



capable of meeting the dexos 1(TM) specification.



- Like dexos(TM) the new ILSAC GF-5 standard will call for more sophisticated additives. The API will begin licensing marketers during



October 2010, to produce and distribute GF-5 certified products, which are expected to include SAE 0W-20, 0W-30, 5W-20, 5W-30 and



10W-30 oils.



2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 347



Corporate Average Fuel Economy (CAFE) Requirements Effect on Fuel Economy



Since CAFE standards were first introduced in 1974, the fuel economy of cars has more than doubled, while the fuel economy of light trucks has



increased by more than 50 percent. Proposed CAFE standards call for a continuation of increased fuel economy in new cars and trucks. To meet



these future requirements, all aspects of vehicle operation are being looked at more critically than ever before.



New technology being introduced in GM vehicles designed to increase vehicle efficiency and fuel economy include direct injection, cam phasing,



turbocharging and active fuel management (AFM). The demands of these new technologies on engine oil also are taken into consideration when



determining new oil specifications. AFM for example can help to achieve improved fuel economy. However alternately deactivating and activating



the cylinders by not allowing the intake and exhaust valves to open contributes to additional stress on the engine oil.



Another industry trend for meeting tough fuel economy mandates has been a shift toward lower viscosity oils.



dexos 1(TM) will eventually be offered in several viscosity grades in accordance with engine needs: SAE 0W-20, 5W-20, 0W-30 and 5W-30.



Using the right viscosity grade oil is critical for proper engine performance. Always refer to the Maintenance section of a vehicle Owner Manual



for the proper viscosity grade for the engine being serviced.



GM Oil Life System in Conjunction With dexos(TM) Supports Extended Oil Change Intervals



To help conserve oil while maintaining engine protection, many GM vehicles are equipped with the GM Oil Life System. This system can provide



oil change intervals that exceed the traditional 3,000 mile (4,830 km) recommendation.



The dexos(TM) specification, with its requirements for improved oil robustness, compliments the GM Oil Life System by supporting extended oil



change intervals over the lifetime of a vehicle.



If all GM customers with GM Oil Life System equipped vehicles would use the system as intended, GM estimates that more than 100 million



gallons of oil could be saved annually.



GM dexos 2(TM) Information Center Website



Refer to the following General Motors website for dexos 2(TM) information about the different licensed brands that are currently available:



http://www.gmdexos.com



GM dexos 2(TM) Engine Oil Trademark and Icons



The dexos(TM) specification and trademarks are exclusive to General Motors, LLC.



Only those oils displaying the dexos(TM) trademark and icon on the front label meet the demanding performance requirements and stringent



quality standards set forth in the dexos(TM) specification.



Look on the front label for any of the logos shown above to identify an authorized, licensed dexos 2(TM) engine oil.



GM dexos 2(TM) Engine Oil Specification



- dexos 2(TM) is approved and recommended by GM for use in Europe starting in model year 2010 vehicles, regardless of where the vehicle



was manufactured.



- dexos 2(TM) is the recommended service fill oil for European gasoline engines.



Important



The Duramax(TM) diesel engine is the exception and requires lubricants meeting specification CJ-4.



2010 Cadillac Truck Escalade/ESV RWD V8-6.2L Page 348



- dexos 2(TM) is the recommended service fill oil for European light-duty diesel engines and replaces GM-LL-B-025 and GM-LL-A-025.



- dexos 2(TM) protects diesel engines from harmful soot deposits and is designed with limits on certain chemical components to prolong



catalyst life and protect expensive emission reduction systems. It is a robust oil, resisting degradation between oil changes and maintaining



optimum performance longer.



The dexos(TM) Specification and Trademarks are Exclusive to General Motors, LLC.

- Exhaust Camshaft Position Actuator Solenoid Valve Control Circuit High Voltage Bank 2



Circuit/System Description



The camshaft position actuator system enables the Engine Control Module (ECM) to change the timing of the camshafts while the engine is



operating. The Camshaft Position Actuator Solenoid Valve signal from the ECM is pulse width modulated (PWM). The ECM controls the



Camshaft Position Actuator Solenoid Valve duty cycle by controlling the amount of solenoid valve ON time. The Camshaft Position Actuator



Solenoid Valve controls the advance or the retard of each camshaft. The Camshaft Position Actuator Solenoid Valve controls the oil flow that



applies the pressure to advance or retard the camshafts.



Ignition voltage is supplied directly to the Camshaft Position Actuator Solenoid Valve. The ECM controls the solenoid valve by grounding the



control circuit with a solid state device called a driver. The driver is equipped with a feedback circuit that is pulled-up to a voltage. The ECM can



determine if the control circuit is open, shorted to ground, or shorted to a voltage by monitoring the feedback voltage.



Conditions for Running the DTC



* The engine speed is greater than 80 RPM.



* The ignition voltage is between 10-18 V.



* The ECM has commanded the Camshaft Position Actuator Solenoid Valve ON and OFF at least once during the ignition cycle.

control modules can be temporary with no apparent symptom or complaint; this does not mean the control module is faulty. Do not replace a



control module based only on a history U-code.



* Do not replace a control module reporting a U-code. The U-code identifies which control module needs to be diagnosed for a communication



issue.



* Communication may be available between the BCM and the scan tool with either the low or high speed GMLAN serial data system



inoperative. This condition is due to the BCM using both the low and high speed GMLAN systems.



* Use to determine if the module uses high or low speed GMLAN serial data communications.



* Some control modules may not have internal protection for specific control circuits and may open a B+ or ignition fuse. If a fuse is open and



the B+ or ignition circuit is not shorted to ground, ensure none of the control circuits are shorted to ground before replacing the control



module.



* This diagnostic can be used for any control module that is not communicating, regardless of the type of serial data circuit it is connected to,



providing the vehicle is equipped with the control module.

Diagnostic Fault Information



Circuit/System Description



During a frontal crash of sufficient force the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the



deployment loop in order to deploy the driver steering wheel air bag. The SDM performs continuous diagnostic tests on the deployment loops to



check for proper circuit continuity and for shorts to ground or voltage. There are 2 shorting bars used within the driver steering wheel air bag coil



connector which will short together both driver steering wheel air bag stage 1 control circuit and driver steering wheel air bag stage 1 control circuit



and both driver steering wheel air bag stage 2 control circuit and driver steering wheel air bag stage 2 control circuit when the connector is



disconnected. This will help to prevent unwanted deployment of the air bag during servicing.

DTC Descriptor



DTC B3055 00



- No Transponder Modulation or No Transponder



Circuit/System Description



When an ignition key is inserted into the ignition lock cylinder and the ignition mode is changed, the transponder embedded in the head of the key



is energized by the exciter coils surrounding the ignition lock cylinder. The energized transponder transmits a signal that contains its unique value,



which is received by the body control module (BCM). The BCM then compares this value to a value stored in memory. If the value is not correct,



the BCM disables engine start.



Conditions for Running the DTC



Ignition is in the Accessory or Run position.



Conditions for Setting the DTC



The BCM is unable to measure the ignition key transponder value.



Action Taken When the DTC Sets



* Vehicle starting will be disabled.



* The security indicator will illuminate. A service message will be displayed in the driver information center.



Conditions for Clearing the DTC



* A current DTC will be cleared when the BCM detects a valid transponder value from the ignition key.



* A history DTC will be cleared after 100 malfunction-free ignition cycles.

DTC B096A 02



- Hazard Lamps Switch Backlight Circuit Short to Ground



Diagnostic Fault Information



Circuit/System Description



The body control module (BCM) supplies a voltage reference through the instrument panel cluster dimming voltage reference circuit to the



instrument panel cluster lamps dimmer switch, which is part of the headlamp switch. When the dimmer switch is placed in a desired brightness



position, reference voltage is applied through the dimmer switch rheostat and the cluster lamps dimmer switch signal circuit to the BCM. The BCM



interprets this voltage signal, then applies a pulse width modulated (PWM) voltage to the LED dimming supply circuit to all related interior lamps,



illuminating them to the desired level of brightness.

- Passenger Seat Cushion Heater Sensor Circuit High Voltage/Open



Diagnostic Fault Information



Circuit/System Description



The heated seat temperature sensor that set this diagnostic trouble code (DTC) is located in the seat cushion just under the seat cover with the seat



heating element. The seat heating control module supplies a 5 V reference voltage through the temperature sensor signal circuit and a ground



through the low reference circuit to the sensor. The module monitors the voltage of the sensor signal circuit to determine the temperature of the



seat. The temperature sensor varies in resistance based on the temperature of the heating element causing the signal voltage to change. Once the seat



reaches the set temperature, the module will then cycle the control circuit of the heating elements ON and OFF in order to maintain the desired seat



temperature based on the feedback voltage from the sensor.
