Description

Communication error with swivel actuator (LH)

Detection condition

• AFS control module detected communication error with the swivel actuator (LH) for 5 s or more with the ignition switched ON (engine off or on).

Fail-safe function

• The swivel actuator (LH) is stopped at the position when the malfunction is determined.

• The swivel actuator (RH) is moved to the center, or the swivel actuators (LH) and (RH) are moved to the center.

• Control of the headlight auto leveling system is continued with the headlight leveling actuator positioned −0.65° from where the malfunction is determined.

Possible cause

• Front combination light (LH) connector or terminal malfunction

• AFS control module connector or terminal malfunction

• Short to ground in wiring harness between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

• Short to power supply in wiring harness between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

• Open circuit in wiring harness between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

• Swivel actuator (LH) malfunction

• AFS control module malfunction

Step

Inspection

Action

1

• Switch the ignition off.

• Disconnect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• Disconnect the front combination light (LH) connector.

• Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.

• Is the connector normal?

Yes

Go to the next step.

No

Repair or replace the connector, then go to Step 7.

2

• Disconnect the AFS control module connector.

• Inspect the connector engagement and connection condition and inspect the terminals for damage, deformation, corrosion, or disconnection.

• Is the connector normal?

Yes

Go to the next step.

No

Repair or replace the connector, then go to Step 7.

3

• Verify that the front combination light (LH) and AFS control module connectors are disconnected.

• Inspect for continuity between the following terminals (wiring harness-side) and body ground:

• Front combination light (LH) terminal K

• Front combination light (LH) terminal J

• Is there continuity?

Yes

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has a short to ground.

Go to Step 7.

No

Go to the next step.

4

• Verify that the front combination light (LH) and AFS control module connectors are disconnected.

• Reconnect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• Switch the ignition ON (engine off or on).

• Measure the voltage at the following terminals (wiring harness-side):

• Front combination light (LH) terminal K

• Front combination light (LH) terminal J

• Is the voltage 0 V?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to power supply.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has a short to power supply.

Go to Step 7.

5

• Verify that the front combination light (LH) and AFS control module connectors are disconnected.

• Switch the ignition off.

• Disconnect the negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• Inspect for continuity between the following terminals (wiring harness-side):

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

• Is there continuity?

Yes

Go to the next step.

No

Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals:

• AFS control module terminal AC—Front combination light (LH) terminal K

• AFS control module terminal Y—Front combination light (LH) terminal J

If there is a common connector:

• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit.

• Repair or replace the malfunctioning part.

If there is no common connector:

• Repair or replace the wiring harness which has an open circuit.

Go to Step 7.

6

• Always reconnect all disconnected connectors.

• Reconnect the disconnected negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• 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 front combination light (LH), then go to the next step.

(See FRONT COMBINATION LIGHT REMOVAL/INSTALLATION.)

No

Go to Step 8.

7

• Always reconnect all disconnected connectors.

• Reconnect the disconnected negative battery cable.

  (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION [SKYACTIV-G 2.5].)

• 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.

8

• Are any other DTCs displayed?

Yes

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