Diagnosis Function

DIAGNOSIS FUNCTION







The diagnosis function makes the master warning light and the multi-information display to come on, and CRUISE main indicator light blinks as shown in the illustration, when a malfunction occurs in the dynamic laser cruise control system, and store the diagnosed result in the ECM.

NOTE:
- The master warning light goes off if the system returns to normal condition.
- Since the stored data in the ECM is erased by disconnecting the EFI fuse and the battery terminal, do not disconnect them until finishing the inspection.
