Troubleshooting Method |
---|---|---|
DTC Based Diagnosis |
The diagnosis procedure is based on the DTC that is stored. |
The malfunctioning part is identified based on the DTC detection conditions using a process of elimination. The possible trouble areas are eliminated one-by-one by use of the Techstream and inspection of related parts. |
Symptom Based Diagnosis (No DTCs stored) |
The diagnosis procedure is based on problem symptoms. |
The malfunctioning part is identified based on the problem symptoms using a process of elimination. The possible trouble areas are eliminated one-by-one by use of the Techstream and inspection of related parts. |
2. DESCRIPTION
(a) Each system data and the Diagnostic Trouble Codes (DTCs) can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use the Techstream to check for malfunctions and perform repairs.
3. CHECK DLC3
(a) The vehicle ECUs use ISO 15765-4 communication protocol. The terminal arrangement of the DLC3 complies with ISO 15031-3 and matches the ISO 15765-4 format.

DESCRIPTION
The ECM detects a cruise control switch signal and sends it to the combination
meter assembly through CAN. Then the SET indicator light comes on.
The SET indicator light circuit uses CAN for communication. If there
is a malfunct ...
