Detection condition

• The auto leveling control module received error configuration data from the instrument cluster for 30 s or more with the ignition switched ON (engine off or on).

Fail-safe

• Control of the headlight auto leveling system is continued.

Possible cause

NOTE:

• To correctly write the configuration data sent from the instrument cluster to the auto leveling control module to the auto leveling control module, 30 s or more need to have elapsed since the ignition was switched ON (engine off or on).

• DTCs are stored in the instrument cluster.

• Instrument cluster configuration not implemented

• Instrument cluster internal memory malfunction

• Instrument cluster configuration data error

• Auto leveling control module malfunction

Step

Inspection

Action

1

• Retrieve the instrument cluster DTCs using the M-MDS.

• Is the DTC displayed?

Yes

Repair the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

2

• Using the M-MDS, perform the instrument cluster configuration with the As-Built data.

  (See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)

• Clear the auto leveling control module DTCs using the M-MDS.

  (See CLEARING DTC [AUTO LEVELING CONTROL MODULE].)

• Switch the ignition ON (engine off or on) and wait for 30 s or more.

• Retrieve the auto leveling control module DTCs using the M-MDS.

  (See DTC INSPECTION [AUTO LEVELING CONTROL MODULE].)

• Is the same DTC displayed?

Yes

Using the M-MDS, perform the instrument cluster configuration (using As-Built data) again, then go to the next step.

(See INSTRUMENT CLUSTER CONFIGURATION (USING AS-BUILT DATA).)

No

Go to the next Step 4.

3

• Clear the auto leveling control module DTCs using the M-MDS.

  (See CLEARING DTC [AUTO LEVELING CONTROL MODULE].)

• Switch the ignition ON (engine off or on) and wait for 30 s or more.

• Retrieve the auto leveling control module DTCs using the M-MDS.

  (See DTC INSPECTION [AUTO LEVELING CONTROL MODULE].)

• Is the same DTC displayed?

Yes

Replace the auto leveling control module, then go to the next step.

(See AUTO LEVELING CONTROL MODULE REMOVAL/INSTALLATION.)

No

Go to the next step.

4
