WIRING DIAGRAM





INSPECTION PROCEDURE
NOTICE:
- Turn the power switch off before measuring the resistances of CAN bus main wires and CAN bus branch wires.
- After the power switch is turned off, check that the key reminder warning system and lighting system are not operating.
- Before measuring the resistance, leave the vehicle as is for at least 1 minute and do not operate the power switch, any other switches, or the doors. If any doors need to be opened in order to check connectors, open the doors and leave them open.
HINT: Operating the power switch, any other switches, or a door triggers related ECU and sensor communication on the CAN. This communication will cause the resistance value to change.

PROCEDURE

1. CHECK OPEN IN CAN BUS WIRE (RADIO AND NAVIGATION ASSEMBLY BRANCH WIRE)
(a) Turn the power switch off.
(b) Disconnect the radio and navigation assembly connector.




(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPLACE RADIO AND NAVIGATION ASSEMBLY BRANCH WIRE OR CONNECTOR
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (POWER SOURCE CIRCUIT)




(a) Measure the resistance according to the value(s) in the table below.
Standard resistance:





(b) Measure the voltage according to the value(s) in the table below.
Standard voltage:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE RADIO AND NAVIGATION ASSEMBLY
