INSPECTION PROCEDURE
NOTICE:
HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change.

Diagnosis system
1. DIAGNOSIS FUNCTION
The diagnosis function makes the light and the
multi-information display come on, and the CRUISE
main indicator light blink as shown in the illustration.
When a malfunction occurs in the dynamic laser
cruise control system, the DTCs are stored in the
ECM ...
