DTC Descriptors
DTC B2495 01
- Liftgate Latch Control Circuit Short to Battery
DTC B2495 02
- Liftgate Latch Control Circuit Short to Ground
DTC B2495 04
- Liftgate Latch Control Circuit Open
Diagnostic Fault Information
Circuit/System Description
The latch motor is a bi-directional motor and cinch or unlatch operation is the result of the direction of the motor rotation. The liftgate control
module controls the latch motor through the control circuits by supplying power and ground in the appropriate polarity. The motor control circuits
are monitored by the liftgate control module prior to activation for a high or low condition and during motor operation for an insufficient current
flow condition.
Conditions for Running the DTC
The system voltage is 9-16 V.
Conditions for Setting the DTC
B2495 01
The liftgate control module detects a short to voltage in the liftgate latch motor cinch control circuit or the liftgate latch motor release control
circuit.
B2495 02
The liftgate control module detects a short to ground in the liftgate latch motor cinch control circuit or the liftgate latch motor release control
circuit.
B2495 04
The liftgate control module detects an open/high resistance in the liftgate latch motor cinch control circuit or the liftgate latch motor release control
circuit.
Action Taken When the DTC Sets
The liftgate will be inoperative in the power and manual modes.
Conditions for Clearing the DTC
* The DTC will be current for as long as the fault is present.
* When the fault is no longer present, the DTC will be a history DTC.
* A history DTC will clear after 50 ignition cycles.

DTC Descriptors
DTC B3604 02
- Adjustable Pedal Forward Switch Circuit Short to Ground
DTC B3605 02
- Adjustable Pedal Rearward Switch Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
Ground is supplied at all times to the adjustable pedal switch. When the pedals switch is pressed, a 5 V reference voltage is applied through the
switch contacts and the switch signal circuit to the memory seat control module. The memory seat control module then commands the adjustable
pedals motor to move in response to the switch signal.
Conditions for Running the DTC
The memory seat control module must be powered.
Conditions for Setting the DTC
The forward and rearward switch signal circuits are active at the same time.

Circuit/System Description
The wheel speeds are detected by active wheel speed sensors. Each wheel speed sensor receives a 12 V reference voltage from the electronic brake
control module (EBCM) and provides an alternating current square wave signal to the EBCM. As the wheel spins, the EBCM uses the frequency of
the square wave signal to calculate the wheel speed. The EBCM sends the wheel speed information as a high speed controller area network (CAN)
serial data message.
Conditions for Running the DTC
Ignition ON
Conditions for Setting the DTC
A supervised periodic message that includes the wheel speed serial data has not been received.
Action Taken When the DTC Sets
Specific subsystems will not function or operate in degraded mode.
Conditions for Clearing the DTC
A current DTC clears when the diagnostic runs and passes.
