Diagnostic Procedure

DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT CLUSTER SWITCH CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See 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 C (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 C 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 V (wiring harness-side) and cluster switch terminal B (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 V and cluster switch terminal B. 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 open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a open circuit. Go to Step 6.
5	INSPECT CLUSTER SWITCH Inspect the cluster switch. (See TCS OFF SWITCH INSPECTION .) (See POWER LIFTGATE (PLG) FRONT SWITCH INSPECTION .) (See LANE-KEEP ASSIST SYSTEM OFF SWITCH INSPECTION .) (See 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. (See CLUSTER SWITCH REMOVAL/INSTALLATION .)
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the disconnected negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear 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 DTC inspection for the instrument cluster 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, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION .)
6		No	Go to the next step.
7	VERIFY IF OTHER DTCs DISPLAYED Are any other DTCs displayed?	Yes	Repair the malfunctioning part according to the applicable DTC troubleshooting. (See DTC TABLE [INSTRUMENT CLUSTER] .)
7		No	DTC troubleshooting completed.
