Cruise Control, Active Signal

Other systems sometimes need to know when the Cruise Control system is engaged.
The Cruise Control system therefore sends information to this effect from pin J (9).

- TRIONIC system
To cause the engine to go down to basic charging pressure.
1 Initiate the diagnosis mode, see Self Diagnosis Mode
Check the voltage applied to pin J (9) of the Cruise Control connector.
It should be 12 V when the switch is in the SET, RESUME or ON/OFF positions.
If the voltage is not OK, go to Before Control Module Replacement.
If the voltage is OK, continue with point 2.





2 Check the wiring for continuity or a short circuit as follows:
Measure the resistance across pin J (9) of the Cruise Control connector and pin 36 of the TRIONIC control module.
If the resistance is > 1 ohm, check the wiring and remedy the fault.
If the resistance is <=1 ohm, the fault is in the other system. Continue fault diagnosis with "TRIONIC engine management system".
