• Instrument cluster malfunction

Diagnostic Procedure

Step

Inspection

Action

1

DETERMINE IF MALFUNCTION LOCATION IS AFS OFF SWITCH

•  Display the following AFS control module AFS_ST PIDs using the M-MDS.
(See PID/DATA MONITOR INSPECTION [ADAPTIVE FRONT LIGHTING SYSTEM (AFS)].)

•  Inspect the PID display when the AFS OFF switch is turned on/off.

•  Does the PID display switch normally in conjunction with the AFS OFF switch being turned on/off?

Yes

Go to Step 3.

No

Go to the next step.

2

PERFORM AFS OFF SWITCH INSPECTION

•  Disconnect the negative battery cable.
(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

•  Remove the AFS OFF switch.
(See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) OFF SWITCH REMOVAL/INSTALLATION.)

•  Inspect the AFS OFF switch.
(See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) OFF SWITCH INSPECTION.)

•  Is the AFS OFF switch normal?

Yes

Replace the AFS control module.

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

No

Replace the AFS OFF switch.

(See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) OFF SWITCH REMOVAL/INSTALLATION.)

3

VERIFY AFS DISPLAY ILLUMINATION

•  Connect the negative battery cable.
(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5 (WITHOUT i-stop)].)

(See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-D 2.2].)

•  Display the following instrument cluster WL+IL simulation items using the M-MDS.
(See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].)

•  Does the AFS OFF indicator light illumination turn off when the warning light, indicator light illumination is operated to off?

Yes

The system is operating normally.

No

Replace the instrument cluster.
