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)
Cooling system
On-vehicle inspection
1. INSPECT FOR COOLANT LEAK
CAUTION:
Do not remove the radiator cap while the engine and
radiator are still hot. Pressurized, hot engine coolant
and steam may be released and cause serious
burns.
NOTICE:
Before performing each inspection, turn the A/ ...

Operation check
1. REMOVE CHECK FUNCTION
Check that the key reminder warning buzzer
sounds.
With the driver side door closed, insert the key
into the ignition key cylinder and then turn the
key to LOCK or ACC.
Check that the buzzer sounds intermittently if
the driver side door ...
