DIAGNOSIS

CONTROLLER AREA NETWORK (CAN)

54C-230

STEP 48. 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 49.
NO :  Repair the damaged parts.

STEP 49. 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

.

DIAGNOSIS

CONTROLLER AREA NETWORK (CAN)

54C-231

(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 

50   .

NO :  If the resistance measures less than 1 k

Ω, repair the 

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

DIAGNOSIS

CONTROLLER AREA NETWORK (CAN)

54C-232

STEP 50. Check the CAN_L line (communication line only) 
between the A/T- ECU connector and ABS-ECU connector 
for short to ground. Measure the resistance at A/T- ECU 
connector B-19.

NOTE: When diagnosing CAN BUS on vehicles with 

manual transmission (M/T) disregard A/T-ECU and it’s wir-
ing circuits and measure between ABS-ECU and 
ENGINE-ECU only.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

DIAGNOSIS

CONTROLLER AREA NETWORK (CAN)

54C-233

(1) Disconnect A/T- ECU connector B-19 and ABS-ECU 

connector A-02, and measure the resistance at the harness 
side of A/T- ECU connector B-19.

(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 A/T- ECU connector 

terminal 14 and body ground.

OK: 1 k
