(4) Measure the resistance between joint connector (3) 

terminal 15 and combination meter connector terminal 15.

OK: 2 ohms or less

(5) Measure the resistance between joint connector (3) 

terminal 4 and combination meter connector terminal 14.

OK: 2 ohms or less

CAUTION

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

P.54C-5

.

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, go to 

Step 6.

NO :  If either of the resistances measures more than 2 

ohms or all the resistances measure more than 2 
ohms, repair the wiring harness between joint 
connector (3) and the combination meter connector, 
and then go to Step 2.

STEP 6. Check the terminator resistor inside the 
combination meter. Measure the resistance at combination 

meter connector C-101.

CAUTION

A digital multimeter should be used. For details refer to 

P.54C-4

.

(1) Disconnect combination meter C-101, and measure the 

resistance at the component side of combination meter 
connector C-101.

(2) Measure the resistance between combination meter 

connector terminals 14 and 15.

OK: 120 

± 20 Ω

Q: Does the resistance measure 120 

± 20 Ω?

YES : If the resistance measures 120 

± 20 Ω, go to Step 2.

NO :  If the resistance does not measure 120 

± 20 Ω, 

replace the combination meter, and then go to Step 2.

STEP 7. Check the CAN bus lines (communication line 
only) between intermediate connector C-29 and joint 
connector (3). Measure the resistance at intermediate 

connector C-29 and 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 intermediate 

connector C-29, and measure the resistance between the 
wiring harness side connector of joint connector (3) C-02 
and the female side connector of intermediate connector 
C-29 (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 

terminal 12 and joint connector (3) terminal 20.

OK: 2 ohms or less

(5) Measure the resistance between intermediate connector 

terminal 11 and joint connector (3) terminal 9.

OK: 2 ohms or less

CAUTION

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

P.54C-5

Q: Do all the resistances measure 2 ohms or less?

YES : If all the resistances measure 2 ohms or less, go to 

Step 2.

NO :  If either of the resistances measures more than 2 

ohms or all the resistances measure more than 2 
ohms, repair the wiring harness between joint 
connector (3) and the intermediate connector, and 
then go to Step 2.
