Diagnostic Code Check

If system malfunctions while vehicle is in cruise control mode, cruise control functions will be canceled, and CRUISE light will blink 5 times, indicating fault codes are stored in cruise control Electronic Control Unit (ECU).

Intermittent failures may cause CRUISE light to flicker or illuminate. Light will go out after fault goes away. Fault may or may not be present at the time of testing; however, the corresponding fault code may be retained in ECU memory.

Before proceeding with cruise control system self-diagnostics, ensure basic inspection of system has been performed. If no faults were found during basic inspection, proceed with self-diagnostics.
