Ω or less

CAUTION

Strictly observe the specified wiring harness 
repair procedure. For details refer to 

P.54D-8

.

Q: Are the check results normal?

YES : 

<All the voltages measure 2 

Ω or less> Go 

to Step 6  .

NO : 

<Either or all of the resistances measure 
more than 2 

Ω> Repair the wiring harness 

between joint connector (CAN2) and the 
combination meter connector.

STEP 6. Resistance measurement at C-02 
combination meter connector.

CAUTION

A digital multimeter should be used. For details 
refer to 

P.54D-8

.

(1) Remove the combination meter, and measure at

STEP 7. Connector check: A-07 joint connector 
(CAN1), A-16 intermediate connector and C-112 
engine-ECU <M/T> or engine-A/T-ECU <A/T> 
connector
NOTE: When checking A-07 joint connector (CAN1), 
disassemble and check the engine compartment 
relay box by referring to 

P.54D-616

.

CAUTION

The strand end of the twist wire should be within 
10 cm from the connector. For details refer to 

P.54D-8

.

When checking the joint connector, ensure that its 
wiring harness side is not damaged.

Q: Are the check results normal?

YES : 

Go to Step 8 .

NO : 

Repair the connector, or replace the joint 
connector (front wiring harness assembly).

STEP 8. Resistance measurement at the A-16 
intermediate connector.

CAUTION

A digital multimeter should be used. For details 
refer to 

P.54D-8

.

CAUTION

The test wiring harness should be used. For 
details refer to 

P.54D-8

.

(1) Disconnect the connector, and measure at its 

male-side intermediate connector (at the control 
wiring harness side).

(2) Ignition switch: OFF (LOCK) 

CAUTION

When measuring the resistance, disconnect the 
negative battery terminal. For details refer to 

P.54D-8

.

(3) Ensure that the negative battery terminal is 

disconnected.

(4) Resistance between A-16 intermediate connector
