Self-Diagnostic System: Notes
WARNING:
Deactivate air bag system before performing any service operation. See appropriate AIR BAG RESTRAINT SYSTEM article. Do not apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.
NOTE:
Self-diagnostic testing for Protege 1.5L is not available from manufacturer. Perform appropriate component tests. If all components test okay, repair wiring as necessary. See WIRING DIAGRAMS .
One of 2 on-board diagnostic modes may be utilized. The CONDITION DETECTION MODE indicates trouble in cruise control system. The OPERATION MODE checks correct input signals to the cruise control module. Modes are performed using either the New Generation Star (NGS) scan tool or cruise indicator light.
Perform OPERATION MODE first. If system passes all operation modes, perform CONDITION DETECTION MODE. If condition detection mode does not output any DTCs, check components in the following order: main switch, cruise control module, cruise brake switch, brakelight switch, cruise control switch, actuator and vehicle speed sensor. See COMPONENT TESTS. If no components are defective repair wiring as necessary. See WIRING DIAGRAMS.
