DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-307

STEP 51. Check the CAN_L line (communication line only) 
between intermediate connector C-29 and joint connector 
(3) 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 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) 

terminal 20 and body ground.

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).

CONTROLLER AREA NETWORK (CAN)

54C-308

STEP 52. Check ABS-ECU connector A-02 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 ABS-ECU connector A-02 in good condition?

YES : Go to Step 53.
NO :  Repair the damaged parts.

STEP 53. Check the CAN_L line (communication line only) 
between intermediate connector C-29 and ABS-ECU 
connector for short to ground. Measure the resistance at 

intermediate connector C-29.

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 ABS-ECU 

connector A-02, and measure the resistance at the male 
side of intermediate connector C-29 (at front wiring harness 
side).

(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 intermediate connector 

terminal 12 and body ground.

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, go to Step 

54   .

NO :  If the resistance measures less than 1 k

Ω, repair the 

wiring harness between intermediate connector C-29 
and ABS-ECU connector.
