WIRING DIAGRAM
CAUTION / NOTICE / HINT
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 (See page ).
|
2. |
CHECK FOR OPEN IN CAN BUS WIRE (RADIO AND DISPLAY RECEIVER ASSEMBLY BRANCH WIRE) |
(a) Disconnect the G49 radio and display receiver assembly connector. |
|
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

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 (See page |
|
(b) Disconnect the G48 and G49 radio and display receiver assembly connectors.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
