Description
For CVT models, transmission range switch is turn ON when the selector lever is P or N.
For M/T models, park/neutral position (PNP) range switch is ON when the selector lever is Neutral position.
ECM detects the position because the continuity of the line (the ON) exists.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-356, "Component Function Check".
Is the inspection result normal? YES >> GO TO 3.
NO >> Proceed to EC-356, "Diagnosis Procedure".
3.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
CAUTION:
Always drive vehicle at a safe speed.
With GST
Follow the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-356, "Diagnosis Procedure".
NO >> INSPECTION END
Component Function Check
1.CHECK PNP SIGNAL FUNCTION
With CONSULT
Is the inspection result normal? YES >> GO TO 2.
NO >> Proceed to EC-356, "Diagnosis Procedure".
2.PERFORM COMPONENT FUNCTION CHECK
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-356, "Diagnosis Procedure".
Diagnosis Procedure
1.INSPECTION START
Check which type of transmission the vehicle is equipped with.
Which type of transmission? CVT models>>GO TO 2.
M/T models>>GO TO 6.
2.CHECK TRANSMISSION RANGE SWITCH POWER SUPPLY
Is the inspection result normal? YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK TRANSMISSION RANGE SWITCH POWER SUPPLY CIRCUIT

NO >> Repair or replace error-detected parts.
4.CHECK TRANSMISSION RANGE SWITCH SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK TRANSMISSION RANGE SWITCH
Check the transmission range switch. Refer to TM-165, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace transaxle assembly. Refer to TM-283, "Removal and Installation".
6.CHECK PARK/NEUTRAL POSITION (PNP) SWITCH POWER SUPPLY
Is the inspection result normal? YES >> GO TO 7.
NO >> Perform the trouble diagnosis for power supply circuit.
7.CHECK PNP SWITCH INPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 8.
NO >> Repair or replace error-detected parts.
8.CHECK PNP SWITCH
Check the PNP switch. Refer to TM-17, "PARK/NEUTRAL POSITION (PNP) SWITCH : Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace PNP switch. Refer to TM-21, "Removal and Installation".
