DI - 174 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

d. Take a multimeter to measure the continuity of No. 30
and No. 87 terminal of IG2 relay R12.
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 A / C switch A power and ground harness and connector
a. Ignition switch:LOCK. .

b. Disconnect A/C switch A connector B037.

c. Take a multimeter to measure resistance between No. 2
terminal of B037 and grounding.
Standard voltage:
Multimeter connecting terminal Standard value

B037(2)-grounding About 0Ω

d. Ignition switch: ON.

e. Take a multimeter voltage gear to measure the voltage
between No. 1 terminal of B037 and grounding.
Standard voltage:

Multimeter connecting terminal Standard value

B037(1)-grounding Storage battery voltage

Check if the result is ok?
Yes>go to Step 4.

No> Repair or replace A / C switch A power or ground harness.
