connector terminal Nos.26 and 27

OK: 120

± 20 Ω

Q: Is the check result normal?

YES :

<Within 120

± 20 Ω> Go to Step 8 .

NO :

<Not within 120

± 20 Ω> Go to Step 3 .

STEP 3. Connector check: C-09 joint connector
(CAN2) and C-02 combination meter connector

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 result normal?

YES :

Go to Step 4.

NO :

Repair the connector, or replace the joint
connector. Then go to Step 2.

STEP 4. Resistance measurement at C-09 joint
connector (CAN2).

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 the

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 C-09 joint connector (CAN2)

CAUTION

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

P.54D-8

.

Q: Are the check result normal?

YES :

<All the voltages measure 2

Ω or less> Go

to Step 6 .
