Diagnostic Fault Information

Circuit/System Description

The body control module (BCM) supplies battery positive voltage to the backlight dimmer switch, which is part of the headlamp switch. When the

backlight dimmer switch is placed in a desired brightness position, reference voltage is applied 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.

Conditions for Running the DTC

The ignition is ON.

Conditions for Setting the DTC

B1405 03, B1529 03, or B257B 03

The BCM detects less than 0.3 V on the dimmer switch signal circuit.

B1405 07, B1529 07, or B257B 07

The BCM detects a voltage greater than 12.2 V on dimmer switch signal circuit.

Action Taken When the DTC Sets

The BCM will not dim or illuminate any LED backlighting supplied by the backlight lamp control circuits.

Conditions for Clearing the DTC

* The condition responsible for setting the DTC no longer exists.

* A history DTC will clear once 100 consecutive fault free ignition cycles have occurred.

Tires/Wheels - OE Tire Shake/Vibration Information

INFORMATION

Bulletin No.: 03-03-10-007G

Date: July 13, 2012

Subject: Information on Tire/Wheel Characteristics (Vibration, Balance, Shake, Flat Spotting) of GM Original Equipment Tires

Models:

2013 and Prior GM Passenger Cars and Light Duty Trucks

Supercede:

This bulletin is being revised to add a reference to GM approved tire force variation measurement equipment. Please discard Corporate Bulletin

Number 03-03-10-007F (Section 03 - Suspension).

The purpose of this bulletin is to help explain that, under certain circumstances, a customer may notice a slight tire shake within the first few

miles/kilometers of vehicle operation.

Tires may be designed with a nylon overlay configuration engineered to enhance the tire's integrity at high speeds. This allows the tires to be driven

at higher speeds without excessive heat buildup.

Important

Before measuring tires on GM approved tire force variation measurement equipment, the vehicle MUST be driven a minimum of 24 km

(15 mi) to ensure removal of any flat spotting (The tendency to "flat spot" is less likely as the tire accumulates mileage).

When parked overnight, or for a period of time, the tires may set (flat spot) and require a few miles/kilometers before heating up to their normal

operating temperature. Until the tires warm up, a slight tire shake may be felt but should subside quickly.

Important

DEALERS SHOULD REFRAIN FROM ATTEMPTING REPAIRS OR REPLACING COMPONENTS for this temporary tire flat

P2094, and P2095 is not set.

* The engine speed is greater than 560 RPM.

* The engine is operating for greater than 1 s.

* The engine coolant temperature is between -48 to +143掳C (-54 to +289掳F).

* The engine oil temperature is between -48 to +180掳C (-54 to +356掳F).

* The engine must accelerate such that the camshaft position actuator system is commanded from the park position to the phased position. This

is considered a cam control cycle. There must be a minimum of 2 cam control cycles for at least 2.5 s each in the phased position.

* DTCs P052B, P052D, P054B, and P054D run continuously once the above conditions are met for greater than 20 s.

Conditions for Setting the DTC

* The ECM detects the difference between the desired camshaft position angle and the actual camshaft position angle is greater than 6 degrees.

* The condition exists for greater than 1 s or for a cumulative of 4 s.

Action Taken When the DTC Sets

DTCs P052B, P052D, P054B, and P054D are type B DTCs.

Conditions for Clearing the DTC

DTCs P052B, P052D, P054B, and P054D are type B DTCs.

Diagnostic Aids

* The engine oil condition has a major impact on the camshaft actuator system.

* A low oil level condition may set this DTC. The engine may require an oil change. Inquire with the customer when the last oil change was

performed. You may also monitor the scan tool Engine Oil Life parameter. Advise the customer an oil change may be required.

* Inspect the engine for any recent engine mechanical repairs. An incorrectly installed camshaft, camshaft actuator, or timing chain can cause

this DTC to set.

Circuit/System Verification

Note: The engine oil level and the oil pressure are critical to the correct operation of the camshaft position actuator system. Verify that the

engine has the correct oil level and the correct oil pressure before continuing with this diagnostic.

1. Ignition ON, observe the scan tool DTC information. Verify that none of the following DTCs are set. DTC P0016, P0017, P0018, P0019,

2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 542

Circuit/System Description

The driver and front passenger heated seats are controlled by the seat heating control module that is located under the driver seat cushion. When the

heated seat is active, the module applies power through a common voltage supply circuit to the seat heater elements. The module controls the seat

temperature by providing a pulse width modulation (PWM) ground through the seat heater element control circuit to the heater elements. The

module then monitors the current flow through the heating elements and the rate of change of the temperature sensor to verify correct heated seat

operation.

Conditions for Running the DTC

* DTC B1325 must not be present.

* The engine must be running.

* The seat heating control module must be powered and the heated seat must be enabled.

Conditions for Setting the DTC

B2425 0D or B2430 0D

By measuring current and voltage output to the seat heating elements every 10 seconds, the seat heating control module calculates that the heating

element resistance is above the maximum resistance.

B2425 0B, B2425 0E, B2430 0B, or B2430 0E

By measuring current and voltage output to the seat heating elements every 10 seconds, the seat heating control module calculates that the heating

element resistance is below the minimum resistance.

Action Taken When the DTC Sets

The heated seat function for the affected seat will be disabled.

Conditions for Clearing the DTC

* The current DTC clears when the malfunction is no longer present, and the power mode changes to OFF then back to ACC or RUN.

* The history DTC will clear after 40 consecutive fault-free ignition cycles have occurred.
