Diagnosis System

INTERIOR: REAR SUNSHADE SYSTEM: DIAGNOSIS SYSTEM

1. DESCRIPTION

Power rear sunshade system data and Diagnostic Trouble Codes (DTCs) can be read through the vehicle's Data Link Connector 3 (DLC3). When the system seems to be malfunctioning, use the Techstream to check and perform repairs.

2. CHECK DLC3





HINT
The vehicle's ECU uses the ISO 9141-2 communication protocol. The terminal arrangement of the DLC3 complies with SAE J 1962 and matches the ISO 9141-2 format.





If the result is not as specified, the DLC3 may have a malfunction. Repair or replace the harness and connector.

HINT
Connect the cable of the Techstream to the DLC3, turn the engine switch on (IG) and attempt to use the Techstream. If the display indicates that a communication error has occurred, there is a problem either with the vehicle or with the Techstream.

* If communication is normal when the Techstream is connected to another vehicle, inspect the DLC3 of the original vehicle.
* If communication is still not possible when the Techstream is connected to another vehicle, the problem may be in the Techstream itself. Consult the Service Department listed in the Techstream's instruction manual.
