Checking the Cruise Lamp

1 Check that about 12 V is present across pin 8 (H) of the Cruise Control connector and a good ground when the Cruise Control system is activated.







2 If the voltage is OK, check the wiring for continuity or a short circuit by measuring the resistance across pin 8 (H) of the Cruise Control connector and pin 6 of the main instrument display connector.
If the resistance is ≤ 1 ohm, check the bulb.
If the resistance is > 1 ohm, check the wiring and rectify the fault.
3 If no fault has been found after carrying out the above checks, continue fault diagnosis as described "Before Control Module Replacement".
