Diagnosis System

DIAGNOSIS SYSTEM

1. DESCRIPTION
Luggage compartment door opener system data can be read through the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the intelligent tester (with CAN VIM) to check for malfunctions and perform repairs.







2. CHECK DLC3

HINT: The vehicle uses the ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with SAE J1962 and matches the ISO 15765-4 format.






HINT: Connect the cable of the intelligent tester to the DLC3, turn the ignition switch ON and attempt to use the tester. If the screen displays the message UNABLE TO CONNECT TO VEHICLE, there is a problem either with the vehicle or the tester.

If communication is normal when the intelligent tester (with CAN VIM) is connected to another vehicle, inspect the DLC3 on the original vehicle.

If communication is still not possible when the tester is connected to another vehicle, the problem is probably in the tester itself.

Consult the Service Department listed in the tester's instruction manual.
