DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-391

STEP 26. Check the multi-center display unit 
(middle-grade type) for short circuit. Measure the 
resistance at multi-center display unit (middle-grade type) 

connector C-05.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

(1) Disconnect multi-center display unit (middle-grade type) 

connector C-05, and measure the resistance at the 
component side of multi-center display unit (middle-grade 
type) connector C-05.

(2) Measure the resistance between the multi-center display 

unit (middle-grade type) connector terminals 12 and 13.

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-534

.

NO :  If the resistance measures lower than 1 k

Ω, replace 

the multi-center display unit (middle-grade type).

STEP 27. Check data link connector C-125 for loose, 
corroded or damaged terminals, or terminals pushed back 
in the connector.

CAUTION

The strand end of the twisted wire should be within 10 cm 
(4 inches) from the connector. For details refer to 

P.54C-4

.

Q: Is data link connector C-125 in good condition?

YES : Go to Step 28.
NO :  Repair the damaged parts.

STEP 28. Check the CAN_L and H lines (communication 
lines only) between joint connector (3) and the data link 
connector for a short circuit. 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) 

terminals 7 and 18.

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 

29  .

NO :  If the resistance measures less than 1 k

Ω, repair the 

wiring harness between joint connector (3) and the 
data link connector.

STEP 29. Check the CAN_L and H lines (communication 
lines only) between joint connector (3) and the 
intermediate connector for a short circuit. 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 intermediate connector C-29 and 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) 

terminals 9 and 20.

OK: 1 k

 or more

CAUTION

Strictly observe the specified wiring harness repair proce-
dure. For details refer to 

P.54C-5

.

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-534

.

NO :  If the resistance measures less than 1 k

Ω, repair the 

wiring harness between intermediate connector C-29 
and joint connector (3).
