Diagnostic Fault Information

Circuit Description

The seat memory control module monitors the position of the seat motors by using hall effect position sensors which are an internal part of each

motor. The module supplies each sensor with a 12 V reference circuit and a low side signal circuit. During seat motor operation, the hall effect

position sensor provides a determined number of pulse signals for every revolution of the motor shaft. The scan tool displays these pulse signals as

counts that range from 0 - 65,535. The module counts the feedback pulses from each sensor to determine seat position and end of travel limits for

each of the seat motors. High scan tool count values indicate forward or upward seat positions while low count values indicate rearward or

downward seat positions.

Conditions for Running the DTC

* DTC B1325 must not be present.

DTC C0050 5A

- Right Rear Wheel Speed Sensor Circuit Not Plausible

Diagnostic Fault Information

Circuit/System Description

The wheel speeds are detected by active wheel speed sensors and encoder rings. The encoder ring consists of permanent magnets. Each wheel

speed sensor receives 12 V reference voltages from the electronic brake control module (EBCM). The wheel speed sensor produces changing

current between 7-14 mA on the EBCM signal circuit. As the wheel spins, the EBCM uses the frequency of the square wave signal to calculate the

actual wheel speed.

DTC B319A 02

- Right Rear Window Switch Short to Ground

DTC B319A 39

- Right Rear Window Switch Internal Malfunction

Diagnostic Fault Information

Circuit/System Description

When a window switch is pressed on the driver window switch, a serial data message is sent to the body control module (BCM). The BCM

examines the request and checks for messages from other power window motors prohibiting the window movement. If no prohibitive messages

have been received, the BCM will send a serial data message to the passenger window motor or to the appropriate rear window switch which will

perform the command as requested.

Conditions for Running the DTC

Battery voltage must be between 9-16 V.

Conditions for Setting the DTC

B316B 00

The BCM has detected the driver right front or left rear or right rear window switch is active for greater than 60 seconds.

B316B 02

The BCM has detected the driver left front window switch is active for greater than 60 seconds.

B317A 02

The BCM has detected the passenger window switch is active for greater than 60 seconds.

B318A 02

The BCM has detected the left rear window switch is active for greater than 60 seconds

B319A 02

The BCM has detected the right rear window switch is active for greater than 60 seconds

B316B 39, B317A 39, B318A 39, B319A 39

The BCM has detected an internal failure within the affected door switch

Action Taken When the DTC Sets

The affected power window will malfunction.

Conditions for Clearing the DTC

B316B 00, B316B 02, B317A 02, B318A 02, B319A 02

DTC B3933 02

- Air Conditioning Evaporator Temperature Sensor Circuit Short to Ground

DTC B3933 05

- Air Conditioning Evaporator Temperature Sensor Circuit High Voltage/Open

Circuit/System Description

The air temperature sensors are a 2-wire negative temperature co-efficient thermistor. The vehicle uses the following air temperature sensors:

* Air temperature sensor - left upper

* Air temperature sensor - left lower

* Air temperature sensor - right upper

* Air temperature sensor - right lower

* Air temperature sensor - rear upper (only with CJ4)

* Air temperature sensor - rear lower (only with CJ4)

* A/C evaporator temperature sensor

A signal and low reference circuit enables the sensor to operate. As the air temperature surrounding the sensor increases, the sensor resistance

decreases. The sensor signal voltage decreases as the resistance decreases. The sensor operates within a temperature range between -40 to +85掳C

(-40 to +185掳F). The sensor signal varies between 0-5 V. The HVAC control module converts the signal to a range between 0-255 counts. As the

air temperature increases the count value will decrease. If the HVAC control module detects a malfunctioning sensor, then the control module

software will use a default air temperature value. The default action ensures that the HVAC system can adjust the inside air temperature near the

desired temperature until the condition is corrected.

Conditions for Running the DTC

* Ignition ON.

* The HVAC control module is ON.

Conditions for Setting the DTC

The HVAC control module detects the sensor signal out of range. The signal voltage is less than 0.1 V or greater than 4.9 V for more than 50 ms.

Action Taken When the DTC Sets

The system operates using a default value.

Conditions for Clearing the DTC

The sensor signal is within specified range between 0.1-4.9 V.

A/T - Slight Vehicle Movement In Park At Start Up

INFORMATION

Bulletin No.: 08-07-30-026A

Date: May 17, 2011

Subject: Information on Slight Vehicle Movement in Park at Start Up After Cold Soak

Models:

2012 and Prior GM Passenger Cars and Light Duty Trucks

Equipped with Automatic Transmission

Supercede:

This bulletin is being revised to add the 2010-2012 model years. Please discard Corporate Bulletin Number 08-07-30-026 (Section 07 -

Transmission/Transaxle).

Some vehicles may rock or move slightly forward or rearward while in park at start up after cold soak. This condition may be accompanied by a

clunk noise. This is a slight movement that is more often seen visually, rather than felt, when viewed from the outside and using the auto-start

feature, if equipped.

This slight movement is due to the residual transmission fluid in the clutch packs that creates a partial apply on start up. This movement is stopped

by the parking pawl and/or transmission fluid exhausting completely from the clutch packs.

This slight movement has no adverse affects on the transmission and no repair should be attempted. This condition is normal. This can be verified

by comparing with another identically built vehicle under the same cold conditions.

To prevent this condition from occurring, the parking brake should be utilized as per the Owner's Manual recommendations anytime the vehicle is

2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 1005

The ECM detects a short to voltage in the heater circuits of the HO2S when the heater is commanded ON. The condition exists for greater than 4 s

or a cumulative of 30 s.

Action Taken When the DTC Sets

DTCs P0030, P0031, P0032, P0036, P0037, and P0038 are Type B DTCs.

Conditions for Clearing the MIL/DTC

DTCs P0030, P0031, P0032, P0036, P0037, and P0038 are Type B DTCs.

Diagnostic Aids

* If the condition is intermittent, move the related harnesses and connectors, with the engine operating, while monitoring the scan tool circuit

status parameters for the component. The circuit status parameters change from OK or Not Run to Fault if there is a condition with the circuit

or a connection.

* An open fuse in the HO2S heater circuit may be caused by the heater element in one of the sensors. The condition may not be present until

the sensor operates for a period of time. If no fault is present in the heater circuit, monitor the amperage of each heater using the DMM to

determine if one of the heater elements is the cause of the open fuse. Inspect the sensor pigtail or the harness for contacting the exhaust

system.

Circuit/System Verification

1. Engine idling at operating temperature for at least 30 s. Observe the DTC information, DTCs P0030, P0031, P0032, P0036, P0037, and

P0038 should not set.

2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate B52 Heated Oxygen Sensor.

2. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 1 and ground.

Note: The ignition circuit supplies voltage to other components. Make sure you test all circuits for a short to ground or test all components

for being shorted that share the ignition circuit.

瀚慖f the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance. If the circuit tests normal and

the ignition circuit fuse is open, test all the components connected to the ignition circuit and replace as necessary.

3. Connect a test lamp between the heater control circuit terminal 2 and B+. The test lamp should not illuminate.

瀚慖f the test lamp is always ON, test the control circuit for a short to ground. If the circuit/connections test normal, replace the K20 Engine
