± 20 Ω> Go to Step 5 .

STEP 5. Resistance measurement at C-09 joint
connector (CAN2) and C-02 combination meter
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 joint connector (CAN2) and the

combination meter 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

.
