- Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 3.
3.CHECK PNP SIGNAL FUNCTION
With CONSULT
- Turn ignition switch ON.
- Select “P/N POSI SW” in “DATA MONITOR” mode of “ENGINE” using CONSULT. Then check the “P/N POSI SW” signal as per the following conditions.
| Selector lever position | Known-good signal |
| N or P position | ON |
| Except above position | OFF |
Is the inspection result normal? YES >> GO TO 4.
NO >> Proceed to EC-383, "Diagnosis Procedure".
4.PERFORM DTC CONFIRMATION PROCEDURE
- Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
- Start engine and warm it up to normal operating temperature.
- Maintain the following conditions for at least 60 consecutive seconds.
CAUTION: Always drive vehicle at a safe speed.

| B/FUEL SCHDL | 3.25 - 31.8 msec |
| VHCL SPEED SE | More than 64 km/h (40 mph) |
| Selector lever | Suitable position |
- Check 1st trip DTC.
Is 1st trip DTC detected? YES >> Proceed to EC-383, "Diagnosis Procedure".
NO >> INSPECTION END
5.PERFORM COMPONENT FUNCTION CHECK
- Turn ignition switch ON.
- Check the voltage between ECM harness connector terminals as per the following conditions.
Is the inspection result normal? YES >> INSPECTION EN
NO >> Proceed to EC-383, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK TRANSMISSION RANGE SWITCH POWER SUPPLY
- Turn ignition switch OFF.
- Disconnect transmission range switch harness connector.
- Turn ignition switch ON.
- Check the voltage between transmission range switch harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK TRANSMISSION RANGE SWITCH POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect IPDM E/R harness connector.
- Check the continuity between transmission range switch harness connector and IPDM E/R harness connector.
- Also check harness for short to ground.
Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK TRANSMISSION RANGE SWITCH SIGNAL CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between transmission range switch harness connector and ECM harness connector.
- Also check harness for short to ground and to power.
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK TRANSMISSION RANGE SWITCH
Check the transmission range switch. Refer to TM-111, "Component Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace transmission range switch. Refer to TM-220, "Removal and Installation".
5.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
