Diagnostic Procedure

Step	Inspection		Action
1	INSPECT CLUSTER SWITCH CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) 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 6.
2	INSPECT CLUSTER SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the cluster switch connector is disconnected. Inspect for continuity between cluster switch terminal E (wiring harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
2		No	Refer to the wiring diagram and verify whether or not there is a common connector between cluster switch terminal E and body ground. 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 6.
3	INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION 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.
3		No	Repair or replace the connector, then go to Step 6.
4	INSPECT CLUSTER SWITCH CIRCUIT FOR OPEN CIRCUIT Verify that the cluster switch and instrument cluster connectors are disconnected. Inspect for continuity between instrument cluster terminal 1V (wiring harness-side) and cluster switch terminal D (wiring harness-side). Is there continuity?	Yes	Go to the next step.
4		No	Refer to the wiring diagram and verify whether or not there is a common connector between instrument cluster terminal 1V and cluster switch terminal D. 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 6.
5	INSPECT CLUSTER SWITCH Inspect the cluster switch. (Refer to TCS OFF SWITCH INSPECTION .) (Refer to TIRE PRESSURE MONITORING SYSTEM SET SWITCH INSPECTION .) (Refer to BLIND SPOT MONITORING (BSM) SWITCH INSPECTION .) (Refer to LDWS SWITCH INSPECTION .) Is the cluster switch normal?	Yes	Go to the next step.
5		No	Replace the cluster switch, then go to the next step. (Refer to CLUSTER SWITCH REMOVAL/INSTALLATION .)
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery terminal. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the instrument cluster using the M-MDS. (Refer to 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. (Refer to DTC INSPECTION [INSTRUMENT CLUSTER] .) Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the instrument cluster. (Refer to INSTRUMENT CLUSTER REMOVAL/INSTALLATION .) Go to the next step.
6		No	Go to the next step.
7	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair or replace the malfunctioning part according to the applicable DTC troubleshooting. (Refer to DTC TABLE [INSTRUMENT CLUSTER] .)
7		No	DTC troubleshooting completed.
