Input Signal Check
- SET/COAST
Turn ignition on. Set cruise control switch to SET/COAST position and hold. If CRUISE control indicator light flashes 2 times (repeating), SET/COAST circuit is okay. Go to next step. If CRUISE control indicator light does not flash 2 times (repeating), see SYMPTOM DIAGNOSIS and perform appropriate test(s).
- RES/ACC
Turn ignition on. Set cruise control switch to RES/ACC position and hold. If CRUISE control indicator light flashes 3 times (repeating), RES/ACCEL circuit is okay. Go to next step. If CRUISE control indicator light does not flash 3 times (repeating), see SYMPTOM DIAGNOSIS and perform appropriate test(s).
- CANCEL Switches
Turn ignition on. Observe CRUISE control indicator light and activate each cancel switch. Press CANCEL switch to ON and OFF positions. Depress and release brake pedal. On A/T models, move shift lever from "D" to "N" position. On M/T models, depress and release clutch pedal. On all models, if CRUISE control indicator light comes on when switch is in OFF position and goes off when switch is in ON position, circuit for that switch being activated is okay. Go to next step. If CRUISE control indicator does not function as indicated, see SYMPTOM DIAGNOSIS and perform appropriate test(s).
- Vehicle Speed Sensor
Raise and support vehicle. Ensure drive wheels are off the ground. Start engine and slowly accelerate to 25 MPH or greater. Turn main cruise control switch to ON position. If CRUISE control indicator light flashes on and off every .25 second, go to next step. If CRUISE control indicator light does not flash on and off every .25 second, see SYMPTOM DIAGNOSIS and perform appropriate test(s).
- Decrease vehicle speed to 25 MPH or less. If CRUISE control indicator light comes on and stays on, vehicle speed sensor circuit is okay. If CRUISE control indicator light does not come on, see SYMPTOM DIAGNOSIS and perform appropriate test(s). Repair as necessary and retest system.
