Diagnosis System





CRUISE CONTROL: CRUISE CONTROL SYSTEM: DIAGNOSIS SYSTEM

1. CHECK INDICATOR

(a) Turn the engine switch on (IG).

(b) Check that the CRUISE main indicator light turns on when the cruise control switch is turned ON, and that the indicator light turns off when the main switch is turned OFF.

HINT
* If the indicator check result is not normal, proceed to troubleshooting for the combination meter section Problem Symptoms Table.
*




If a malfunction occurs in the speed sensor or stop light switch, etc., during cruise control driving, the ECM activates the AUTO CANCEL of the cruise control and turns ON and OFF the CRUISE main indicator light to inform the driver of a malfunction. At the same time, the malfunction is stored in memory as a diagnostic trouble code.
