Description

Cluster switch circuit malfunction

Detection condition

• Instrument cluster detects an open circuit in the cluster switch circuit for 5 s or more with the ignition switched ON (engine off or on).

Fail-safe function

Not applicable

Possible cause

• Cluster switch connector or terminal malfunction

• Instrument cluster connector or terminal malfunction

• Open circuit in wiring harness between the following terminals:

• Instrument cluster terminal V—Cluster switch terminal B

• Instrument cluster terminal T—Cluster switch terminal C

• Cluster switch malfunction

• Instrument cluster 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 cluster switch 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 5.

2

• Disconnect the instrument cluster 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 5.

3

• Verify that the cluster switch and instrument cluster connectors are disconnected.

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

• Instrument cluster terminal V—Cluster switch terminal B

• Instrument cluster terminal T—Cluster switch terminal C

• 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:

• Instrument cluster terminal V—Cluster switch terminal B

• Instrument cluster terminal T—Cluster switch terminal C

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 5.

4

• Inspect the cluster switch.

  (See DSC OFF SWITCH INSPECTION.)

  (See TIRE PRESSURE MONITORING SYSTEM SET SWITCH INSPECTION.)

  (See BLIND SPOT MONITORING (BSM) OFF SWITCH INSPECTION.)

  (See ADAPTIVE FRONT LIGHTING SYSTEM (AFS) OFF SWITCH INSPECTION.)

  (See LDWS SWITCH INSPECTION.)

• Is the cluster switch normal?

Yes

Go to the next step.

No

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

(See CLUSTER SWITCH REMOVAL/INSTALLATION.)

5

• Always reconnect all disconnected connectors.

• Reconnect the negative battery cable.

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

• Clear the DTC for the instrument cluster using the M-MDS.

  (See CLEARING DTC [INSTRUMENT CLUSTER].)

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

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

  (See DTC INSPECTION [INSTRUMENT CLUSTER].)

• Is the same DTC displayed?

Yes

Repeat the inspection from Step 1.

• If the malfunction recurs, replace the instrument cluster.

  (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)

Go to the next step.

No

Go to the next step.

6

• Are any other DTCs displayed?

Yes

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

(See DTC TABLE [INSTRUMENT CLUSTER].)

No

DTC troubleshooting completed.
