DIAGNOSIS

TSB Revision

CONTROLLER AREA NETWORK (CAN)

54C-419

STEP 2. Check the instrument panel wiring harness side 
CAN bus lines (communication line including the 
combination meter). 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 measure the 

resistance at its female side connector (instrument panel 
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 

terminals 11 and 12.

OK: 120 

± 20 

Q: Does the resistance measure 120 

± 20 ?

YES : If the resistance measures 120 

± 20 Ω, go to Step 8.

NO :  If the resistance does not measure 120 

± 20 Ω, go to 

Step 3.

STEP 3. Check joint connector (3) C-02 and combination 
meter connector C-101 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: Are joint connector (3) C-02 and combination meter 

connector C-101 in good condition?
YES : 
Go to Step 4.
NO :  Repair the damaged parts. Replace the joint 

connector as necessary. Then go to Step 2.

STEP 4. Check the CAN bus lines (communication line 
including the combination meter) between joint connector 
(3) and the combination meter. Measure the resistance at 

joint connector (3) C-02.

CAUTION

A digital multimeter should be used. For details refer to

.

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 4 and 15.

OK: 120 

± 20 

Q: Does the resistance measure 120 

± 20 ?

YES : If the resistance measures 120 

± 20 Ω, go to Step 7.

NO :  If the resistance does not measure 120 

± 20 Ω, go to 

Step 5.
