5. Check the earth circuit of turn signal lamp switch. IN

a. Ignition switch: LOCK.
b. Disconnect the turn signal lamp switch B034. DI

c. Use a multimeter to measure the resistance between 16#
terminal of turn signal lamp switch B034 and earthing. EG
Standard resistance:

Multimeter connecting terminal Standard value TR

B034(9)-grounding About 0Ω
AX

FR
Check if the result is ok?

Yes>go to Step 6. ST
No > repair or replace the earthing open-circuit wire harness of turn signal lamp switch.
6. Check the turn signal lamp switch. BR

a. Ignition switch: LOCK.
BW
b. Disconnect the connector B034 of light combination switch.

c. Use a multimeter to respectively measure the conductivity
EL
between 7# and 8# terminals of lamplight combination
switch connector B034 and its 9# terminal.
Standard resistance:

Multimeter connecting terminal Standard value

B034(7)-B034(9) About 0Ω

B034(8)-B034(9) About 0Ω

Is the test result ok?

Yes>go to Step 7.
No > repair or replace the lamplight combination switch.
7. Replace the body controller

a. Replace with the same body control module and recheck.
Is the test result ok?
Yes>replace the body controller.

NO>retest the above steps.
