Q:Is the check result normal?

YES:

 Go to Step 3.

NO:

 Replace the combination meter.

STEP 3. Check combination meter connector C-03,
headlight automatic leveling-ECU connector C-110 for
loose, corroded or damaged terminals, or terminals pushed
back in the connector.

Q:Is  combination  meter  connector  C-03,  headlight

automatic  leveling-ECU  connector  C-110  in  good

condition?

YES:

 Go to Step 4.

NO:

 Repair the damaged parts.

STEP 4. Check wiring harness between combination meter
connector C-03 (terminal No. 6/20) and the headlight
automatic leveling-ECU connector C-110 (terminal No. 8/9).

NOTE: 

Prior to the wiring harness inspection, check

intermediate connector C-34, and repair if necessary.

Q:Are  the  wiring  harness  between  combination  meter

connector  C-03  (terminal  No.  6/20)  and  the  headlight

automatic  leveling-ECU  connector  C-110  (terminal  No.

8/9) in good condition?

YES:

 Go to Step 5.

NO:

 Repair the wiring harness.

STEP 5. Retest the system
Check that the headlight automatic leveling warning display is

DIAGNOSIS

Q:Is the check result normal?

YES:

 The trouble 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).

NO:

 Replace the headlight automatic leveling-ECU.

Inspection Procedure 5: The headlight automatic leveling warning light does not go off.

Before  replacing  the  ECU,  ensure  that  the  power  supply
circuit, the ground circuit and the communication circuit are
normal.

TECHNICAL DESCRIPTION (COMMENT)
If the headlight automatic leveling warning display does not go
