DTC Descriptor
DTC B3922 00
- Front Wiper Function Select Circuit
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper
washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high
speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a
resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
Conditions for Running the DTC
The ignition switch is in the ON position.
Conditions for Setting the DTC
The BCM detects a short to ground on the windshield wiper switch low signal circuit.
Action Taken When the DTC Sets
* The BCM will not activate the low speed output.
* The windshield wipers will only operate in the high speed mode.
Conditions for Clearing the DTC
* The DTC will clear the current status when the condition for setting the fault is corrected.
* A history DTC will clear after 50 consecutive ignition cycles without a fault present.

- Ambient Light Sensor Circuit Voltage Below Threshold
DTC B2645 07
- Ambient Light Sensor Circuit Voltage Above Threshold
Diagnostic Fault Information
Circuit/System Description
The ambient light sensor is used to monitor outside lighting conditions. The ambient light sensor provides a voltage signal that will vary depending
on outside lighting conditions. The body control module (BCM) provides a 5 V reference signal to the ambient light sensor. The BCM monitors the
ambient light sensor signal circuit to determine if outside lighting conditions are correct for either daytime running lights (DRL) or automatic lamp
control (ALC) when the headlamp switch is in the AUTO position. In daylight conditions, the BCM will command the DRLs ON. In low light
conditions, when the headlamps switch is in AUTO position, the BCM will command the low beam headlamps ON.
Conditions for Running the DTC
Battery voltage must be between 9-16 V.
Conditions for Setting the DTC
B2645 03
The BCM detects voltage is below 0.196 volt in the ambient light sensor signal circuit.
B2645 07
The BCM detects voltage is above 4.9 volts in the ambient light sensor signal circuit or if the ambient light sensor ground circuit is open.
Action Taken When the DTC Sets
The automatic lamp control will default to ON.

DTC Descriptor
DTC B1015 00
- Vehicle Identification Number (VIN) Information Error
Circuit/System Description
When the ignition is turned ON, the object alarm module receives the vehicle identification number (VIN) from the body control module (BCM).
The object alarm module will compare the VIN received to the VIN stored in memory.
Conditions for Running the DTC
* DTC B1325 is not set
* Ignition voltage is between 9-16 volts
Conditions for Setting the DTC
The VIN stored in the object alarm module does not match the received VIN.
Action Taken When the DTC Sets
* The parking assist system is disabled.
* The object alarm module sends a serial data message to the instrument panel cluster (IPC) to display SERVICE PARK ASSIST message in
the driver information center (DIC).
Conditions for Clearing
* The DTC will transition to history when the fault is no longer present.
* A history DTC will clear after 100 malfunction-free ignition cycles.

DTC C0306 05
- Motor A or B Circuit Short to Battery or Open
Diagnostic Fault Information
Circuit/System Description
The transfer case encoder motor (TCEM) is a bi-directional, permanent magnet, DC motor. When energized, through motor control A or motor
control B, the ground is provided by the opposing motor control circuit and then grounded through the transfer case shift control module (TCCM)
ground circuit, the TCEM, through a series of gears, rotates the transfer case control actuator shaft which moves the transfer case two/four wheel
drive actuator cam and transfer case high/low shift fork to shift the transfer case between the following modes or ranges:
* 2WD HI
* 4WD Auto
* 4WD HI
Conditions for Running the DTC
* Ignition ON
* System voltage 10.5-18 V
Conditions for Setting the DTC
* The TCCM tests the motor circuits by checking for unexpected voltage.
* The TCCM supplies voltage on each of the motor circuits and reads the voltage back on the other circuit.
* If the TCCM detects a low voltage return when a high voltage is expected, or a high voltage return when a low voltage is expected, the DTC
is logged.
* The fault must remain current for 1 second to set the DTC.
Action Taken When the DTC Sets
* All shifting is disabled.
* The mode light shall flash upon a requested mode change and then return to the current mode.
* The SERVICE 4WD indicator remains illuminated for the remainder of the current ignition cycle.
Conditions for Clearing the DTC
* The TCCM clears the DTC once the conditions for setting the DTC are no longer present.
* A history DTC clears after 40 consecutive warm-up cycles without a fault present.
* History DTCs can be cleared using a scan tool.
Diagnostic Aids
* It is possible to have windings inside the motor shorted to the case, resulting in a short to ground, causing this DTC to set.
* The default actions for C0321 may set C0306.
* EL-49741 - harness is a good source for 9 V.

DTC Descriptor
DTC B3922 00
- Front Wiper Function Select Circuit
Diagnostic Fault Information
Circuit/System Description
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper
washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high
speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a
resistor ladder, and windshield washer switch signal circuit is used to determine washer operation.
Conditions for Running the DTC
The ignition switch is in the ON position.
Conditions for Setting the DTC
The BCM detects a short to ground on the windshield wiper switch low signal circuit.
Action Taken When the DTC Sets
* The BCM will not activate the low speed output.
* The windshield wipers will only operate in the high speed mode.
Conditions for Clearing the DTC
* The DTC will clear the current status when the condition for setting the fault is corrected.
* A history DTC will clear after 50 consecutive ignition cycles without a fault present.

Conditions for Running the DTC
* Battery voltage is between 9-16 volts
* The ignition is ON.
Conditions for Setting the DTC
The BCM detects a short to voltage in the steering wheel control switch signal circuit.
Action Taken When the DTC Sets
The BCM will ignore switch inputs.
Conditions for Clearing the DTC
* The condition responsible for setting the DTC no longer exists.
* A history DTC will clear once 100 consecutive malfunction free ignition cycles have occurred.

Circuit/System Description
With each press of a keyless entry transmitter button, a message containing the current battery state of the transmitter is sent to the remote control
door lock receiver (RCDLR) along with the commanded keyless entry function.
Conditions for Running the DTC
A keyless transmitter button is pressed.
Conditions for Setting the DTC
The DTC sets after 3 consecutive low battery signals from the same programmed transmitter.
Action Taken When the DTC Sets
The keyless entry system is inoperative.
Conditions for Clearing the DTC
The DTC is cleared when a normal transmitter voltage signal is received from the programmed transmitter that set the DTC.
Diagnostic Aids
The keyless entry transmitter used in the 2-Way Advanced Remote Start System is unique to the system. When servicing or replacing a transmitter,
ensure that the correct transmitter is used. The correct transmitter part number can be found in the Accessory section of the parts catalog.
Attempting to replace a 2-Way Advanced Remote Start transmitter with a regular service part may result in a failure to program the transmitter.
