Diagnostic Procedure

Step	Inspection		Action
1	INSPECT CLUSTER SWITCH CONNECTOR 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.
1		No	Repair or replace the connector, then go to Step 5.
2	INSPECT INSTRUMENT CLUSTER CONNECTOR 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.
2		No	Repair or replace the connector, then go to Step 5.
3	INSPECT FOR OPEN CIRCUIT IN CLUSTER SWITCH CIRCUIT 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.
3		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 CLUSTER SWITCH Inspect the cluster switch. (See DSC OFF SWITCH INSPECTION .) (See TIRE PRESSURE MONITORING SYSTEM SET SWITCH INSPECTION .) (See BLIND SPOT MONITORING (BSM) SWITCH INSPECTION .) (See LDWS SWITCH INSPECTION .) Is the cluster switch normal?	Yes	Go to the next step.
4		No	Replace the cluster switch, then go to the next step. (See CLUSTER SWITCH REMOVAL/INSTALLATION .)
5	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect 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.
5		No	Go to the next step.
6	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [INSTRUMENT CLUSTER] .)
6		No	DTC troubleshooting completed.
