Diagnostic Procedure

DTC P0819:00 (FW6A-EL) - DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
1		No	Go to the next step.
2	VERIFY 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.
6		No	Go to the next step.
7	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR SHORT TO GROUND Verify that the selector lever component and instrument cluster connectors are disconnected. Inspect for continuity between the following terminals (wiring harness-side) and body ground: Selector lever component terminal E Selector lever component terminal C Selector lever component terminal D Is there continuity?	Yes	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 ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. Go to Step 11.
7		No	Go to the next step.
8	INSPECT SELECTOR LEVER COMPONENT CIRCUIT FOR SHORT TO POWER SUPPLY Verify that the selector lever component and instrument cluster connectors are disconnected. Switch the ignition ON (engine on). Measure the voltage at the following terminals (wiring harness-side): Selector lever component terminal E Selector lever component terminal C Selector lever component terminal D Is the voltage 0 V ?	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. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 11.
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: Verify that the battery voltage is 8 V or more. Drive the vehicle for 1 s or more under the following condition: Selector lever position: Except D position Drive the vehicle for 1 s or more under the following conditions: Selector lever position: D position Up switch: On 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.
