Major Symptom	Expected Cause	Items to Check and Measures
Shock when shifting to and from D/R Motor run-up when shifting to and from D/R	Faulty position sensor "N" setting	Use the "N" setting jig and adjust the "N" setting.
	Faulty position sensor "N" setting	(Refer to "Automatic Transaxle System – Position Sensor")
	Faulty oil pressure in the valve body	Replace valve body assembly or inspect/replace transaxle assembly
Faulty engine start Current gear not indicated in the Cluster Warning Lamp ON Engine stall while stopped Creeping not possible Auto parking release disabled	Faulty CAN terminating resistance/circuit	Check TCM/battery management system module.
	Faulty CAN terminating resistance/circuit	Check TCM wiring connector connection.
	Faulty position sensor circuit fuse	Check fuse and junction box terminal, and repair.
	Faulty position sensor wiring connector	Check for foreign substance in the wiring connector, and check for gap on the terminal.
	Faulty position sensor wiring connector	Check sealing on unused pin, and check for corrosion on the terminal.
	Faulty reverse lamp circuit	Check reverse lamp ground, and reassemble if necessary.
	Faulty position sensor wiring ground	Check wiring ground, and reassemble if necessary.
	Position sensor faulty code	Inspect in accordance with the inspection flow, then replace position sensor if necessary.

- Removal

• With the ignition off, press the brake pedal and press the "N" button (A) for 3 seconds.
