Self-Diagnostic System: Notes

WARNING: Before servicing steering column or instrument panel components on vehicles with Supplemental Inflatable Restraint (SIR) system, disable air bag system. See DISABLING & ACTIVATING SUPPLEMENTAL RESTRAIN SYSTEM in AIR BAG RESTRAINT SYSTEMS - PRIZM article. DO NOT apply electrical power to any component on steering column without deactivating air bag system. Air bag may deploy.
CAUTION: When battery is disconnected, radio will go into anti-theft protection mode. Obtain radio anti-theft protection code from owner prior to servicing vehicle.
NOTE: Before proceeding with cruise control self-diagnostic system, ensure preliminary inspection has been performed. See PRELIMINARY INSPECTION under TROUBLE SHOOTING.

When vehicle is in cruise control mode, system will cancel due to a malfunction in actuator, speed sensor or CRUISE ON-OFF switch circuit. When cruise control functions are canceled, CRUISE indicator light will blink 5 times, indicating a 2-digit DTC is stored in Cruise Control Module (CCM) memory. DTCs are retrieved using cruise control indicator light. Scan tool diagnostics are not available for cruise control system.

If a fault or symptom is present, but no DTCs were set, perform system check. See TEST 1: SYSTEM CHECK  under SYSTEM TESTS.
