Diagnosis System

DIAGNOSIS SYSTEM

1. DIAGNOSIS FUNCTION







a. The diagnosis function makes the master warning light and the multi-information display come on, and the CRUISE main indicator light blinks as shown in the illustration. When a malfunction occurs in the dynamic laser cruise control system, the DTCs are stored 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 and ETCS fuses or the battery terminal, do not disconnect them until the inspection has been completed.

2. DESCRIPTION

a. The ECM controls the cruise control function and dynamic laser cruise control in a vehicle. Data on the cruise control system, dynamic laser cruise control system and the DTCs can be read from DLC3 in the vehicle. If the CRUISE main indicator light does not come on after the DTC check, there is a malfunction in the cruise control and dynamic laser cruise control system.

Use the intelligent tester to check and solve the problem.
