Cruise control system — description and check

1. All models have an electronically controlled throttle body — there is no accelerator cable or cruise control cable. When you select the speed that you want to maintain, the PCM controls vehicle speed by opening and closing the throttle plate by means of a computer-controlled solenoid (motor) inside the throttle body.

2. The diagnostic procedures for trouble- shooting the cruise control system are beyond the scope of this manual, but if the system can’t be set, or the set speed doesn’t cancel when the brake pedal is depressed, check the fuses. Start with the fuses in the engine compartment fuse and relay box, then check the fuses in the under-dash fuse and relay box. If the set speed doesn’t cancel when the CANCEL button is depressed, check the fuse for that circuit.

3. Other than checking the fuses, the diagnostic procedures for troubleshooting the cruise control system on these models are beyond the scope of this manual. A dealer service department should handle any further testing.
