Checking the Cruise Control (Without TCS)

Checking Cruise Control, Steps 1 & 3:

1 Connect an ISAT scan tool, contact the AFM system and enter command code EE6i.

The status of the system is displayed on the ISAT:


^ With the Cruise Control in the "ON" position (the car must be driven faster than 40 km/h with the SET button depressed) PAE63-ON. If not, go to point 2.

^ With the Cruise Control in the "OFF" position PAE63-OFF. If not, go to point 5.


2 Check fuse FA2 (manual) or FA9 (automatic). Also check whether the Cruise Control is in working order.


If it is not, replace the fuse or carry out a fault diagnosis of the Cruise Control system.

If the Cruise Control system is OK, continue as described below.

3 With the ignition switched OFF, connect the break-out box to the ECM wiring harness (ECM disconnected) and check the lead to pin 36 of the ECM for continuity/shorting to ground.


Take remedial action if the cable is faulty.

Checking Cruise Control, Steps 5 & 6:

4 If the cable is OK, the ECM may be faulty. Review "Before Replacing ECM."

5 With the ignition switched off, connect the break-out box to the ECM wiring harness (ECM disconnected). Turn the ignition switch to the Drive position and check whether voltage is present on pin 36 of the ECM.

If it is not, the ECM may be faulty. Review "Before Replacing ECM."


If it is, continue as described below.

6 Unplug the connector from the control module of the Cruise Control system and check whether voltage is still present on pin 36. If it is, carry out a fault diagnosis of the Cruise Control system.


If voltage is still present on pin 36 of the ECM, check the lead to it for shorting to battery positive voltage.

Take remedial action if the wiring is faulty.

7 If problem persists, the ECM may be faulty. Review "Before Replacing ECM."
