DI - 180 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

d. Measure the conduction between No.30 and 87 terminals
of low beam lamp relay R12 with a multimeter.
Standard resistance:
Storage battery voltage Standard value

Battery positive pole connecting to
Terminal 85 and negative pole About 0Ω
connecting to Terminal 86

Check if the result is ok?
Yes>go to Step 3.
No> Replace the same specification of relay.

3. Check blower and blower relay, and blower and ground harness and connectors
a. Ignition switch:LOCK.

b. Disconnect blower connector B057, and the air volume button is in the maximum gear.

c. Take a multimeter to measure resistance between No. 2
terminal of B057 and grounding.
Standard resistance:
Multimeter connecting terminal Standard value

B057(2)-grounding About 0Ω

d. Ignition switch: ON.

e. Take a multimeter voltage gear to measure the voltage
between No. 1 terminal of B057 and grounding.
Standard voltage:

Multimeter connecting terminal Standard value

B057(1)-grounding Storage battery voltage

Check if the result is ok?
Yes> Replace blower.

No> If the voltage is abnormal, repair or replace the open harness between the blower and the blower
relay. If the resistance is abnormal, go to Step 4.
