INSPECTION PROCEDURE

NOTICE:
Inspect the fuses for circuits related to this system before performing the following inspection procedure.

HINT
Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.

PROCEDURE

1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and branch wire.

CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.

NEXT -- Continue to next step.

2. CHECK FOR OPEN IN CAN BUS WIRE (RADIO AND DISPLAY RECEIVER ASSEMBLY BRANCH WIRE)

(a) Disconnect the G31 radio and display receiver assembly connector.





(b) Measure the resistance according to the value(s) in the table below.

NG -- REPAIR OR REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY BRANCH WIRE OR CONNECTOR (CANH, CANL)
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (RADIO AND DISPLAY RECEIVER ASSEMBLY - BATTERY AND BODY GROUND)

(a) Connect the cable to the negative (-) battery terminal.

NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.





(b) Disconnect the G31 and G33 radio and display receiver assembly connectors.

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