Self-Diagnostic System
When vehicle is in cruise control mode, system will cancel due to a malfunction in actuator, speed sensor or speed control switch circuit. When cruise control functions are canceled, CRUISE indicator 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 code(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 cause CRUISE indicator to display a one digit function code, if circuit tested is okay. See CRUISE CONTROL CIRCUIT FUNCTION TEST under TROUBLE SHOOTING . Function codes are not to be confused with trouble codes. One digit function codes are only used in the function test. Two digit trouble codes indicate that a fault has occurred in the system.
