Parking lights


1. If only a single lamp is faulty, check that this lamp's fuse and bulb are OK and that the fuse is live.


2. Connect a scan tool and select "READ SWITCHES" from the menu and then "PARKING LIGHTS".

Read the scan tool display.

If the scan tool shows " OFF ", continue with point 3.

If the scan tool shows " ON ", continue with point 4.

3. Check whether a 12 V power supply is present on pin 3 of the light switch connector. If a power supply is present, see point 4. If it is not, check the wiring between the output of the Maxi 2 fuse and pin 3 of the light switch connector for breaks/shorting.


4. Connect a BOB and check whether a voltage supply is present on pin 16. Check the wiring for breaks/shorting between pin 16 of the ICE module connector and pin 6 of the light switch connector.


If the wiring is OK, the fault is in the lights switch. Change the switch.

5. Read "LH PARKING LIGHTS" and "RH PARKING LIGHTS" to check whether they are in working order. If any of the circuits is faulty, check the wiring for breaks/shorting by measuring the resistance between the fuses and:


• ICE module connector pin 4 (left-hand).

• ICE module connector pin 28 (right-hand).

6. Unplug the lamp connectors and use an ohmmeter to check the ground connections of the lamps as follows:





• between pin 4 of the connector and a good grounding point for the front parking lights.

• between pin 3 of the connector and a good grounding pint for the side marker lights.

• between pin 2 of the connector and a good grounding point for the rear parking lights.

The resistance should be < 1 ohm.

If the resistance is OK, go to point 7.

If the resistance is not OK, check the wiring for breaks/shorting.

7. Using a voltmeter, check the lamp's power supply as follows:


• between connector pin 3 and a good grounding point for the front parking lights.

• between connector pin 1 and a good grounding point for the side marker lights.

• between connector pin 1 for the left-hand rear parking lights and connector pin 3 for the right-hand rear parking lights and a good grounding point. A reading of 12 V should be obtained.

8. If a different reading is obtained, check the wiring for breaks/shorting as follows:


• for the front parking lights, between the fuse and the lamp.

• for the rear parking lights, between ICE module connector pins 27 (left-hand) and 3 (right-hand).
