Retrieving Trouble Codes
- Codes from cruise control ECU self-diagnostic system are retrieved through Data Link Connector (DLC) No. 1. Connector is located in right side of engine compartment, near shock tower. Turn ignition switch to ON position. Turn cruise control main switch on. If CRUISE indicator light turns on, leave ignition on and go to next step. If CRUISE indicator light does not turn on, check CRUISE indicator light circuit. See CRUISE CONTROL INDICATOR LIGHT CIRCUIT under SYSTEM TESTS.
- Turn cruise control main switch off. Connect a jumper wire between terminals E1 and Tc at DLC No. 1. See Figure. If any DTCs are present, perform appropriate DTC test under DIAGNOSTIC TESTS . See DIAGNOSTIC TROUBLE CODE (DTC) DEFINITIONS table.
- If no codes are present and CRUISE indicator light begins flashing on and off every .25 second, system is operating normally at this time. If no codes are present and cruise control system fault still exists, perform CRUISE CONTROL FUNCTION TEST under TROUBLE SHOOTING.
