INSPECTION PROCEDURE
NOTICE:
HINT: Operating the ignition switch, any switches, or any doors triggers related ECU and sensor communication with the CAN. This communication will cause the resistance value to change
1 CHECK DLC3
Standard resistance
Result
NOTICE: When the measured value is 133 Ω or more and a CAN communication system diagnostic trouble code is output, there may be a fault besides disconnection of the DLC3 branch wire. For that reason, troubleshooting should be performed again from "HOW TO PROCEED WITH TROUBLESHOOTING" (See page CA-7 ) after repairing the trouble area.
2 CHECK FOR OPEN IN CAN BUS MAIN WIRE (ECM CAN MAIN BUS WIRE)
Standard resistance
REPLACE ECM
3 CHECK FOR OPEN IN CAN BUS MAIN WIRE (NETWORK GATEWAY ECU CAN MAIN BUS WIRE)
Standard resistance
REPLACE NETWORK GATEWAY ECU
4 CHECK FOR OPEN IN CAN BUS MAIN WIRE (JUNCTION CONNECTOR - NETWORK GATEWAY ECU)
Standard resistance
Result
5 CHECK CHECK FOR OPEN IN CANBUS MAIN WIRE (JUNCTION CONNECTOR - ECM)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (JUNCTION CONNECTOR)
6 CHECK FOR OPEN IN CAN BUS MAIN WIRE (JUNCTION CONNECTOR -Å@CAN JUNCTION CONNECTOR)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (JUNCTION CONNECTOR)
7 CHECK FOR OPEN IN CAN BUS MAIN WIRE (CAN JUNCTION CONNECTOR - JUNCTION CONNECTOR)
Standard resistance
8 CHECK FOR OPEN IN CAN BUS MAIN WIRE (CAN JUNCTION CONNECTOR - ECM)
Standard resistance
REPLACE WIRING HARNESS CONNECTOR (CAN JUNCTION CONNECTOR)
Sound Signal Circuit between Radio and Navigation Assembly and
Stereo Jack Adapter
DESCRIPTION
The stereo jack adapter sends an external device sound signal to the radio
and navigation assembly
through this circuit.
The sound signal that has been sent is amplified by the stereo component
amplifier and then is sent to the
speakers.
If there is an open or short in the c ...
