Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	CONFIRM INSTRUMENT CLUSTER DTC • Perform the instrument cluster DTC inspection using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].)
2		No	Go to the next step.
3	INSPECT SELECTOR LEVER COMPONENT CONNECTOR CONDITION • Switch the ignition off. • Disconnect the selector lever component connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
3		No	Go to the next step.
4	INSPECT SELECTOR LEVER COMPONENT • Inspect the M position switch, up switch and down switch. (See M POSITION SWITCH INSPECTION [FW6A-EL].) (See UP SWITCH INSPECTION [FW6A-EL].) (See DOWN SWITCH INSPECTION [FW6A-EL].) • Is there any malfunction?	Yes	Replace the selector lever component, then go to Step 11. (See AUTOMATIC TRANSAXLE SHIFT MECHANISM REMOVAL/INSTALLATION.)
4		No	Go to the next step.
5	INSPECT SELECTOR LEVER COMPONENT GROUND CIRCUIT FOR OPEN CIRCUIT • Verify that the selector lever component connector is disconnected. • Inspect for continuity between selector lever component terminal J (wiring harness-side) and body ground. • Is there continuity?	Yes	Go to the next step.
5		No	Refer to the wiring diagram and verify whether or not there is a common connector between selector lever component terminal J 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 11.
6	INSPECT INSTRUMENT CLUSTER CONNECTOR CONDITION • Disconnect the instrument cluster connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.

Yes	Go to the next step.
8		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Selector lever component terminal E—Instrument cluster terminal H • Selector lever component terminal C—Instrument cluster terminal F • Selector lever component terminal D—Instrument cluster terminal G 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 11.
9	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR OPEN CIRCUIT • Verify that the selector lever component and instrument cluster connectors are disconnected. • Switch the ignition off. • Inspect for continuity between the following terminals (wiring harness-side): ― Selector lever component terminal E—Instrument cluster terminal H ― Selector lever component terminal C—Instrument cluster terminal F ― Selector lever component terminal D—Instrument cluster terminal G • Is there continuity?	Yes	Go to the next step.
9		No	Refer to the wiring diagram and verify whether or not there is a common connector between the following terminals: • Selector lever component terminal E—Instrument cluster terminal H • Selector lever component terminal C—Instrument cluster terminal F • Selector lever component terminal D—Instrument cluster terminal G 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.

10	INSPECT INSTRUMENT CLUSTER • Inspect the instrument cluster. (See INSTRUMENT CLUSTER INSPECTION.) • Is there any malfunction?	Yes	Replace the instrument cluster, then go to the next step. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
10		No	Go to the next step.
11	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Perform the following procedure to ensure that the DTC has been resolved: 1. Verify that the battery voltage is 8 V or more. 2. Drive the vehicle for 1 s or more under the following condition: • Selector lever position: Except D position 3. Drive the vehicle for 1 s or more under the following conditions: • Selector lever position: D position • Up switch: On 4. Drive the vehicle for 1 s or more under the following conditions: • Selector lever position: D position • Down switch: On • Perform the DTC inspection using the M-MDS. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [FW6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [FW6A-EL].)
11		No	DTC troubleshooting completed.
