DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-151

STEP 30. Check intermediate connector C-29 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 intermediate connector C-29 in good condition?

YES : Go to Step 31.
NO :  Repair the damaged parts.

STEP 31. Check the CAN_L-side bus line (communication 
line including ) of the front wiring harness for a short to the 
power supply. Measure the voltage 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 measure the 

voltage at the male side (at front wiring harness side).

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between intermediate connector 

terminal 12 and body ground.

OK: 4.0 V or less

Q: Does the voltage measure 4.0 V or less?

YES : If the voltage measures 4.0 V or less, go to Step 32.
NO :  If the voltage measures more than 4.0 V, go to Step 

52.

STEP 32. Check joint connector (3) C-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

.

Check the joint connector at the wiring harness side for loose, 
corroded or damaged terminals, or terminals pushed back in 
the connector, and also check the short pin behind the connec-
tor for corrosion, deformation and delamination.
Q: Is joint connector (3) C-02 in good condition?

YES : Go to Step 33.
NO :  Repair the damaged parts. Replace the joint 

connector as necessary.

STEP 33. Check the CAN_L line (communication line 
including the combination meter) between joint connector 
(3) and the combination meter connector for a short to the 
power supply. Measure the voltage 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

.

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

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

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 

15 and body ground.

OK: 4.0 V or less

Q: Does the voltage measure 4.0 V or less?

YES : If the voltage measures 4.0 V or less, go to Step 35.
NO :  If the voltage measures more than 4.0 V, go to Step 

34.

STEP 34. Check the CAN_L line (communication line only) 
between joint connector (3) and the combination meter 
connector for a short to the power supply. Measure the 

voltage 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

.

connector C-101, and measure the voltage at the wiring 
harness side of joint connector (3) C-02.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between joint connector (3) terminal 

15 and body ground.

OK: 1.0 V or less

CAUTION

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

P.54C-5
