Problem Symptoms Table

HINT:

Be sure to perform the SYMPTOM SIMULATION procedure before replacing the ECM. If these symptoms do not persist, the cause of the problem may be a poor intermittent electrical contact (open or short) of a wire harness or connector.

Cruise control system

PROBLEM SYMPTOMS TABLE

Symptom	Suspected area
Vehicle speed cannot be set. (The CRUISE main indicator light comes on.)	1. Cruise control switch circuit
	2. If the symptoms still occur after the above area has been inspected and has proven to be normal, replace the ECM.
Pushing the ON-OFF button does not turn the cruise control system on. (Vehicle speed cannot be set.)	1. Stop light switch circuit
	2. Clutch switch circuit
	3. Vehicle speed sensor circuit
	4. Cruise control switch circuit
	5. Park/Neutral position sensor circuit
	6. Shift paddle switch circuit
	7. If the symptoms still occur after the above areas have been inspected and have proven to be normal, replace the ECM.
