Self-Diagnostic System
When vehicle is in cruise control mode, system will cancel due to a malfunction in either actuator, speed sensor or speed control switch circuit. When cruise control functions are canceled, CRUISE light will blink 5 times, indicating 2-digit trouble code(s) are stored in CC ECU memory. See CC ECU FAULT CODE DEFINITION table under SELF-DIAGNOSTICS. Two digit trouble codes(s) will be stored in CC ECU memory until ignition is turned off. See SELF-DIAGNOSTICS .
If a fault or symptom is present, but no trouble codes were set, a circuit function test can be performed. Circuit function test will display a one digit function code if circuit tested is okay. See CRUISE CONTROL CIRCUIT FUNCTION TEST under TROUBLE SHOOTING.
NOTE:
Intermittent failures may cause CRUISE indicator light to flicker or come on. Light will go out after fault goes away. Fault may or may not be present at time of testing; however, a corresponding trouble code may be stored in CC ECU memory. See SELF-DIAGNOSTICS .
