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 module

(LGM) 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 LGM 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 volts.

Conditions for Setting the DTC

B2495 01

The LGM detects a short to voltage in the liftgate latch motor open control circuit or the liftgate latch motor close control circuit.

B2495 02

The LGM detects a short to ground in the liftgate latch motor open control circuit or the liftgate latch motor close control circuit.

B2495 04

The LGM detects an open/high resistance in the liftgate latch motor open control circuit or the liftgate latch motor close 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.
