Diagnostic Procedure

DTC P081C-24; NOT P POSITION SWITCH CIRCUIT MALFUNCTION DIAGNOSTIC PROCEDURE

Step	Inspection		Action
1	INSPECT SELECTOR LEVER COMPONENT CONNECTOR CONDITION Switch the ignition off. Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Disconnect the selector lever component 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 NOT P POSITION SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the selector lever component connector is disconnected. Inspect for continuity between selector lever component terminal G (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 selector lever component terminal G 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 NOT P POSITION SWITCH Inspect the NOT P position switch. (See NOT P POSITION SWITCH INSPECTION .) Is the NOT P position switch normal?	Yes	Go to the next step.
3		No	Replace the selector lever component, then go to Step 6. (See SELECTOR LEVER COMPONENT REMOVAL/INSTALLATION .)
4	INSPECT START STOP UNIT CONNECTOR CONDITION Disconnect the start stop unit 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.
4		No	Repair or replace the connector, then go to Step 6.
5	INSPECT NOT P POSITION SWITCH CIRCUIT FOR OPEN CIRCUIT Verify that the selector lever component and start stop unit connectors are disconnected. Inspect for continuity between start stop unit terminal 1J (wiring harness-side) and selector lever component terminal B (wiring harness-side). 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 start stop unit terminal 1J and selector lever component 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 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 the next step.
6	VERIFY THAT REPAIRS HAVE BEEN COMPLETED Always reconnect all disconnected connectors. Connect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .) Clear the DTC for the start stop unit using the M-MDS. (See CLEARING DTC [START STOP UNIT] .) Switch the ignition ON (engine off). Perform the following work 5 times or more. Operate the selector lever to P position and hold for 5 s or more. Operate the selector lever to other than P position and hold for 5 s or more. Operate the selector lever to P position. Retrieve the start stop unit DTCs using the M-MDS. (See DTC INSPECTION [START STOP UNIT] .) Is the same DTC displayed?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the start stop unit. (See START STOP UNIT 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. (See DTC TABLE [START STOP UNIT] .)
7		No	DTC troubleshooting completed.
