Keyless Vehicle Service Test
Procedure(s)
To carry out a passive key detection test or keyless
vehicle actuator test, the keyless vehicle module
diagnosis entry procedure must be carried out first.
Keyless Vehicle Module Passive key
Diagnosis Entry
1. NOTE: Test mode entry possible on drivers
door only (No entry if drivers door lock
button is defect.
Insert the emergency mechanical key into the
ignition lock cylinder.
2. Rotate the emergency key to position II.
3. Pull, and hold the driver-side front exterior door
handle.
4. Press the driver-side front exterior door handle
lock button 10 times.
5. Rotate the emergency mechanical key to
position 0.
6. Remove the emergency mechanical key from
the ignition lock cylinder.
The keyless vehicle module is now in passive key
diagnosis mode. The module will remain in
diagnosis mode for 30 seconds or until the ignition
lock cylinder is rotated to position II.
Passive Key Detection Test
After each activation of a keyless vehicle system
function, the 30 second time out will be restarted.
1. Press the driver-side front exterior door handle
lock button.
2. Position the passive vehicle key in the defined
reception area of the driver-side front exterior
door handle keyless vehicle antenna. For every
successful detection of the passive vehicle key,
the vehicle indicator lights will flash once.
3. Press the passenger-side front exterior door
handle lock button.
4. Position the passive vehicle key in the defined
reception area of the passenger side front
exterior door handle keyless vehicle antenna.
For every successful detection of the passive
vehicle key, the vehicle indicator lights will flash
once.
5. Press the liftgate or luggage compartment lid
lock button.
6. Position the passive vehicle key in the defined
reception area of the rear bumper keyless
vehicle antenna. For every successful detection
of the passive vehicle key, the vehicle indicator
lights will flash once.
7. Push in the ignition switch turning knob.
8. Position the passive vehicle key in the front of
the passenger compartment. For every
successful detection of the passive vehicle key
by the front interior keyless vehicle antenna, the
vehicle indicator lights will flash once.
9. Position the passive vehicle key towards the
center rear of the passenger compartment. For
every successful detection of the passive vehicle
key by the center interior keyless vehicle
antenna, the vehicle indicator lights will flash
once.
10. Position the passive vehicle key in the luggage
compartment area of the vehicle. For every
successful detection of the passive vehicle key
by the luggage compartment keyless vehicle

DIAGNOSIS AND TESTING
antenna, the vehicle indicator lights will flash
once.
The interior keyless vehicle antenna can also be
activated for testing by pressing the clutch pedal
once, if equipped.
If the vehicle indicator lights do not flash, a fault is
indicated with the antenna or antenna circuit(s).
Keyless Vehicle Module Actuator test
Diagnosis Entry
NOTE: To carry out a keyless vehicle actuator test,
the keyless vehicle module diagnosis entry
procedure must be carried out first.
NOTE: Test mode entry possible on drivers door
only (No entry if drivers door lock button is defect).
1. Insert the emergency mechanical key into the
ignition lock cylinder.
2. Rotate the emergency key to position II and
back to position I.
3. Pull, and hold the driver-side front exterior door
handle.
4. Press the driver-side front exterior door handle
lock button 10 times.
5. Rotate the emergency mechanical key to
position 0.
6. Remove the emergency mechanical key from
the ignition lock cylinder.
The keyless vehicle module is now in Actuator test
diagnosis mode. The module will remain in
diagnosis mode for 30 seconds.
Keyless Vehicle Actuator Test
After each activation of a keyless vehicle system
function, the 30 second time out will be restarted.
1. Press the driver-side front exterior door handle
lock button. The vehicle indicator lights will flash
once.
2. Press the passenger-side front exterior door
handle lock button. The vehicle indicator lights
will flash once.
3. Pull the driver-side front exterior door handle.
The vehicle indicator lights will flash once.
4. Pull the passenger-side front exterior door
handle. The vehicle indicator lights will flash
once.
5. Pull the passenger-side rear exterior door
handle. The vehicle indicator lights will flash
once.
6. Pull the driver-side rear exterior door handle.
The vehicle indicator lights will flash once.
7. Press the liftgate or luggage compartment lid
exterior release switch. The vehicle indicator
lights will flash once.
8. Press the liftgate or luggage compartment lid
lock switch. The vehicle indicator lights will flash
once.
9. Press the clutch pedal (if equipped). The vehicle
indicator lights will flash once.
10. Press the brake pedal. The vehicle indicator
lights will flash once.
11. Push in the ignition switch turning knob. The
vehicle indicator lights will flash once.
12. Pull out the ignition switch turning knob. The
vehicle indicator lights will flash once.
13. Insert the emergency key into the ignition lock
cylinder. The vehicle indicator lights will flash
once.
14. Press the interior unlock switch. The vehicle
indicator lights will flash once.
If the vehicle indicator lights do not flash, a fault is
indicated with the the component or circuit(s) of
the operated component.
