Door Latch

E56150

Description

Item

Door latch

Door latch unlatch motor

Central/double locking motor

The keyless vehicle locking system requires unique
door latches.

The door latches are equipped with electric motors
that replace the mechanical unlatch function of the
exterior door handle when the vehicle is in keyless
vehicle system mode. This is because the exterior
door handle is already in a semi pulled state before
the latch unlatch command is received by the latch
lock motors, the latch linkage is not in a position
to engage with the exterior door handle.

If the emergency key is used to enter the vehicle,
the standard mechanical latch linkage is utilized.

Central and double locking is still controlled by the
door control modules, however the commands to
lock and unlock are relayed through the keyless
vehicle module on the high-speed CAN bus circuit.

Interior Unlock Switch

E56179

The interior unlock switches function, is to unlock
the rear doors and passenger door locks when the
vehicle has been entered using the passive entry
system in drivers unlock mode.

DIAGNOSIS AND TESTING

Keyless Vehicle Module

E56101

The keyless vehicle module is at the heart of the
keyless vehicle system. It communicates with the
PJB and with the instrument cluster on the medium
speed CAN bus circuit. The keyless vehicle module
stores the passive vehicle key codes. If a new
keyless vehicle module is installed in a vehicle, the
following sequence must be followed before the
system can function.

• Using WDS Program Module routine, program

the keyless vehicle module.

• Using the Initialize System routine, initialize the

keyless vehicle module to the CJB and to the
steering column lock control unit.

• Using the Teach Key function, teach the

minimum number of passive keys required.

Inspection and Verification (Vehicles
with Keyless Entry)

1. Verify the customer concern.

2. Visually inspect for obvious signs of mechanical

or electrical damage.

3. If an obvious cause for an observed or reported

concern is found, correct the cause (if possible)
before proceeding to the next step.

4. If the cause is not visually evident, connect WDS

to the data link connector.

5. Select the Remote Keyless Entry menu.

6. Retrieve the diagnostic trouble codes (DTC)

and refer to the Diagnostic Trouble Code (DTC)
Index - Keyless Vehicle Module.

7. If no DTC(s) are stored in the keyless vehicle

module, retrieve the DTC(s) from the CJB and
refer to the DTC index - CJB.
