DTC B0208 01

- Rear Blower Motor Speed Circuit Short to Battery

DTC B0208 06

- Rear Blower Motor Speed Circuit Low Voltage/Open

Circuit/System Description

The blower motor control module - auxiliary is an interface between the HVAC control module and the blower motor. The blower motor speed

control from the HVAC control module, battery positive and ground circuits enable the blower motor control module - auxiliary to operate. The

HVAC control module provides a pulse width modulation (PWM) signal to the blower motor control module - auxiliary in order to command the

blower motor speed. The blower motor control module - auxiliary transfers the PWM signal into a corresponding blower motor voltage. The

voltage resides between 2-13 V and changes linear to the height of the PWM signal.

Conditions for Running the DTC

* Ignition ON.

* The HVAC control module is ON.

Conditions for Setting the DTC

B0208 01

The voltage at the HVAC control module output to the blower motor control module - auxiliary is always high.

B0208 06

The voltage at the HVAC control module output to the blower motor control module - auxiliary is always low or floating.

Action Taken When the DTC Sets

The blower motor is inoperative.

Conditions for Clearing the DTC

The condition for setting the DTC is no longer present.

DTC B1395 07

- Control Module Voltage Reference Output Circuit High Voltage

Circuit/System Description

The windshield temperature and inside moisture sensor includes the relative humidity sensor, windshield temperature sensor and humidity sensing

element temperature sensor.

This sensor assembly provides information about:

* Relative humidity level at windshield inside

* Temperature of the windshield inside

* Temperature of the humidity sensor element

The relative humidity sensor measures the relative humidity of the compartment side of the windshield. It also detects the temperature of the

windshield surface on the compartment side. Both values are used as control inputs for the HVAC control module application to calculate the fog

risk on windshield compartment side and ability to reduce fuel consumption by decreasing A/C compressor power to a minimum without causing

any fog. The sensor will also enable partial recirculation mode in order to improve heat-up performance of the passenger compartment under cold

ambient temperature conditions without the risk of mist build-up on the windshield. The humidity sensor element temperature sensor supplies the

temperature of the humidity sensor element. It is only needed if the thermal contact between the humidity sensing element and the inside windshield

surface is not sufficient.

Conditions for Running the DTC

* Ignition ON.

* The HVAC control module is ON.

Conditions for Setting the DTC

B018A 02, B048C 02, B048C 02 or B1395 03

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

B018A 05, B048C 05, B048C 05 or B1395 07

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

Action Taken When the DTC Sets

* The system will use the last valid values as default.

* If no value is read at the time of fault, the HVAC control module uses 60% for humidity.

DTC P162B

- Remote Vehicle Speed Limiting Signal Message Counter Incorrect

Circuit/System Description

When a remote slow-down request is sent from OnStar, the vehicle communication interface module sends a serial data message to the engine

control module (ECM) indicating that reduced vehicle speed has been requested. Once the request is active, the ECM begins reducing engine torque

to match requested vehicle speed and the REDUCED ENGINE POWER message is displayed.

Conditions for Running the DTC

* The engine run time is greater than 5 seconds.

* A remote slow-down request is sent from OnStar

Conditions for Setting the DTC

* The VIN embedded in the slow-down request does not match the VIN stored in the ECM.

* The rolling code counter embedded in the slow-down request does not increment for ten consecutive messages.

Action Taken When the DTC Sets

* ECM ignores all reduced vehicle speed request messages from the vehicle communication interface module.

* The ECM stores DTC P162B in history.

Conditions for Clearing the DTC

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

* A history DTC will clear after 40 malfunction-free ignition cycles have occurred.

DTC C0293 01

- Park Brake Switch Control Short to Battery

DTC C0293 06

- Park Brake Switch Control Low Voltage/Open

DTC C0293 08

- Park Brake Switch Control Performance-Signal Invalid

Circuit/System Description

The electric parking brake control module has an internal motor, apply actuator, release actuator, and temperature sensor. The electric parking brake

control module also contains the logic for applying and releasing the parking brake when commanded by the electric parking brake switch. The

electric parking brake module will perform diagnostics on the electric parking brake switch and its wiring harness to verify it is functioning

properly. When the electric parking brake control module receives a signal from the switch the internal circuit board temperature is checked to

verify it is within operating range before the control module performs the requested operation.

The electric park brake switch control diagnostic checks for failure conditions in the electric park brake switch and associated wiring into the

electric park brake module.

Conditions for Running the DTC

Ignition OFF, ACCESSORY, or RUN mode.

Conditions for Setting the DTC

The electric parking brake module detects a short to battery, short to ground, open circuit, or an internal parking brake switch control malfunction.

Action Taken When the DTC Sets

* The electric parking brake is disabled.

* A DIC message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC

* The electric parking brake module clears the history DTC when a current DTC is not detected in 40 ignition cycles.

* The condition for the DTC is no longer present.

Circuit/System Description

The windshield temperature and inside moisture sensor includes the relative humidity sensor, windshield temperature sensor and humidity sensing

element temperature sensor.

This sensor assembly provides information about:

* Relative humidity level at windshield inside

* Temperature of the windshield inside

* Temperature of the humidity sensor element

The relative humidity sensor measures the relative humidity of the compartment side of the windshield. It also detects the temperature of the

windshield surface on the compartment side. Both values are used as control inputs for the HVAC control module application to calculate the fog

risk on windshield compartment side and ability to reduce fuel consumption by decreasing A/C compressor power to a minimum without causing

any fog. The sensor will also enable partial recirculation mode in order to improve heat-up performance of the passenger compartment under cold

ambient temperature conditions without the risk of mist build-up on the windshield. The humidity sensor element temperature sensor supplies the

temperature of the humidity sensor element. It is only needed if the thermal contact between the humidity sensing element and the inside windshield

surface is not sufficient.

Conditions for Running the DTC

* Ignition ON.

* The HVAC control module is ON.

Conditions for Setting the DTC

B018A 02, B048C 02, B048C 02 or B1395 03

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

B018A 05, B048C 05, B048C 05 or B1395 07

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

Action Taken When the DTC Sets

* The system will use the last valid values as default.

* If no value is read at the time of fault, the HVAC control module uses 60% for humidity.
