DI - 366 Diagnosis - Diagnosis-fault diagnosis of electronic and electrical parts

3. Check the power circuit of body controller.

a. Ignition switch: ON.
b. Use a multimeter to measure the voltage between 1#
terminal and earthing at the back side of body controller
connector B060.
Standard voltage:

Multimeter connection Standard value

B060(1)-grounding Storage battery voltage

Check if the result is ok?

Yes>go to Step 4.
No > check, repair or replace the power wire harness of body controller.
4. Check the earth circuit of body controller.

a. Place the ignition switch at "LOCK" position.

b. Use a multimeter to measure the resistance between 4#
terminal of body controller connector B060 and earthing
point.
Standard resistance:
Multimeter connection Standard value

B060(3)-grounding About 0Ω

Check if the result is ok?
Yes>go to Step 5.

No > check, repair or replace the earth wire harness of body controller.
5. Replace the body controller.

a. Replace with same size of body controller.
b. Use a diagnostic apparatus to confirm DTC fault code.
c. Confirm that there is no DTC fault code in BCM system and BCM-related system function can recover to
normal working state.
Check if the result is ok?

Yes > repair or replace the body controller.
No > check whether other systems operate normally.
