Description

Error signal received from instrument cluster

• AFS OFF switch error signal

• Ignition switch error signal

• Selector lever R position (ATX)/shift lever reverse (MTX) signal error

• Selector lever R position (ATX)/shift lever reverse (MTX) signal not determined

Detection condition

• AFS OFF switch error signal

• AFS control module received the AFS OFF switch error signal for 5 s or more with the ignition switched ON (engine off or on).

• Ignition switch error signal

• AFS control module received the ignition switch error signal for 5 s or more with the ignition switched ON (engine off or on).

• Selector lever R position (ATX)/shift lever reverse (MTX) signal error

• AFS control module received the selector lever R position (ATX)/shift lever reverse (MTX) signal error for 5 s or more with the ignition switched ON (engine off or on).

• Selector lever R position (ATX)/shift lever reverse (MTX) signal not determined

• AFS control module detected the undetermined selector lever R position (ATX)/shift lever reverse (MTX) signal.

Fail-safe function

• AFS OFF switch error signal

• Control of the swivel actuator is continued with the AFS OFF switch fixed in the condition when the malfunction is detected.

• Control of the headlight auto leveling system is continued.

• Ignition switch error signal

• Control of the AFS is continued with the ignition switched ON (engine on).

• Control of the headlight auto leveling system is continued.

• Selector lever R position (ATX)/shift lever reverse (MTX) signal error

• The swivel actuator is moved to the center.

• Control of the headlight auto leveling system is continued.

• Selector lever R position (ATX)/shift lever reverse (MTX) signal not determined

• Control of the swivel actuator is continued with the transaxle range sensor (ATX)/back-up light switch (MTX) fixed in the condition when the malfunction is determined.

• Control of the headlight auto leveling system is continued.

Possible cause

• DTCs are stored in the instrument cluster.

• Instrument cluster malfunction

• AFS control module malfunction

Step

Inspection

Action

1

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

  (See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Are any DTCs displayed?

Yes

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

Go to the next step.

2

• Clear the DTC for the AFS control module using the M-MDS.

  (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

• Switch the ignition ON (engine off or on) and wait for 5 s or more.

• Retrieve the AFS control module DTCs using the M-MDS.

  (See DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

• Is the same DTC displayed?

Yes

Replace the instrument cluster, then go to the next step.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

No

Go to Step 4.

3

• Clear the DTC for the AFS control module using the M-MDS.

  (See CLEARING DTC [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

• Switch the ignition ON (engine off or on) and wait for 5 s or more.

• Retrieve the AFS control module DTCs using the M-MDS.

  (See DTC INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

• Is the same DTC displayed?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the AFS control module.

  (See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) CONTROL MODULE REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

4

• Are any other DTCs displayed?

Yes

Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.

(See DTC TABLE [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

No

DTC troubleshooting completed.
