resistance at joint connector (3) C-02.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-4

.

resistance at the wiring harness side of joint connector (3) 
C-02.

(2) Turn the ignition switch to the "LOCK" (OFF) position.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-4

.

(3) Disconnect the negative battery terminal.

(4) Measure the resistance between joint connector (3) 

terminals 3 and body ground.

OK: 1 k

 or more

Q: Does the resistance measure 1 k

 or more?

YES : If the resistance measures 1 k

Ω or more, go to Step 

18   .

(4 inches) from the connector. For details refer to 

P.54C-4

.

Q: Is SRS-ECU connector C-121 in good condition?

YES : Go to Step 17.
NO :  Repair the damaged parts.

STEP 17. Check the CAN_ H line (communication line only) 
between the SRS-ECU connector and joint connector for a 
short circuit. Measure the resistance at joint connector 
C-02.

• Refer to circuit diagrams GROUP-

90

• Refer to configuration diagrams GROUP-

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

CAUTION

The test wiring harness should be used. For details refer to 

P.54C-4

.

(1) Disconnect joint connector C-02 and SRS-ECU connector 

C-121, and measure the resistance at the wiring harness 
side of joint connector C-02.

(2) Turn the ignition switch to the "LOCK" (OFF) position.

CAUTION

Disconnect the negative battery terminal. For details refer 
to 

P.54C-4

.

(3) Disconnect the negative battery terminal.
