Diagnostic Procedure

When cruise control functions are canceled, CRUISE indicator light will blink 5 times, indicating 2-digit trouble code(s) are stored in cruise control ECU memory. Retrieve trouble code(s). See RETRIEVING DIAGNOSTIC TROUBLE CODES . Perform appropriate DTC test under DIAGNOSTIC TESTS . See DIAGNOSTIC TROUBLE CODE INDEX  table.

If a fault or symptom is present, but no trouble codes were set, perform CRUISE CONTROL FUNCTION TEST  under TROUBLE SHOOTING. Cruise control function test will cause CRUISE indicator light to display a one-digit function code if circuit tested is okay. After performing cruise control function test, if system still does not operate properly and no self-diagnostic trouble codes are present, perform SYMPTOM TESTS  under TROUBLE SHOOTING.
