DIAGNOSIS

YES:

Replace the headlight automatic leveling-ECU.

NO:

The trouble, such as a poor connector connection from

the front height sensor to headlight automatic leveling-
ECU or an open circuit of wiring harness, can be an
intermittent malfunction. (Refer to GROUP 00 - How to use
Troubleshooting/inspection Service Points - How to cope
with Intermittent Malfunction P.00-15.)

Repair the damaged parts.

STEP 2. Check the wiring harness between front height
sensor connector A-04 (terminal No. 1/3) and headlight
automatic leveling-ECU connector D-110 (terminal No.
15/19).

NOTE:

Before the wiring harness check, check the

intermediate connector A-57, and repair that if necessary.

Q:Is wiring harness between front height sensor connector

A-04 (terminal No. 1/3) and headlight automatic leveling-

ECU connector D-110 (terminal No. 15/19) in good

condition?

YES:

Go to Step 3.

NO:
