(4) Measure the resistance between joint connector terminal 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, diagnose 

CAN bus lines thoroughly by referring to 

P.54C-323

.

NO :  If the resistance measures less than 1 k

Ω, repair the 

wiring harness between joint connector C-02 and 
SRS-ECU connector C-121.

STEP 18. Check the CAN_H line (communication line 
including the multi-center display unit ) between joint 
connector (3) and middle-grade multi-center display 
connector for short to ground. Measure the 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

.

(1) Disconnect joint connector (3) C-02, and measure the 

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) 

terminal 8 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 

21   .

NO :  If the resistance measures less than 1 k

Ω, go to Step 

19 .
