STEP 2. Resistance measurement at the C-125
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 front
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-125 intermediate

connector terminal Nos.26 and 27

OK: 120

± 20 Ω

Q: Is the check result normal?

YES :

<Within 120

± 20 Ω> Go to Step 3 .

NO :

<Not within 120

± 20 Ω> Go to Step 26 .

STEP 3. Connector check: C-09 joint connector
(CAN2)

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 and its short pins are not
damaged.

Q: Is the check result normal?

YES :

Go to Step 4.

NO :

Repair a defective connector or replace the
joint connector.
