Checking the Cruise Lamp

1 Check that a 12 V supply is present across pin 8 (H) of the Cruise Control connector and a good earth 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 50 of main instrument panel 2 or pin 2 of main instrument panel 1.
If the resistance is <=1 ohm, check the bulb.
If the resistance if > 1 ohm, check the wiring and remedy the fault.
