Diagnosis Procedure
- CHECK PNP SWITCH POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect Park/neutral position (PNP) switch harness connector.
- Turn ignition switch ON.
- Check the voltage between PNP switch harness connector and ground.TERMINALS VOLTAGE REFERENCE
PNP switch Ground Voltage Connector Terminal F21 1 Ground Battery voltage
Is the inspection result normal?
YES: GO TO 3.
NO: GO TO 2.
- DETECT MALFUNCTIONING PART
Check the following.
- Harness connectors E6, F123
- IPDM E/R harness connector E15
- 10A fuse (No. 58)
- Harness for open or short between PNP switch and IPDM E/R
Repair open circuit or short to ground or short to power in harness or connectors.
- CHECK PNP SWITCH INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT-I
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between PNP switch harness connector and ECM harness connector.TERMINALS CONTINUITY REFERENCE
PNP switch ECM Continuity Connector Terminal Connector Terminal F21 2 E16 102 Existed - Also check harness for short to ground and short to power.
Is the inspection result normal?
YES: GO TO 5.
NO: GO TO 4.
- DETECT MALFUNCTIONING PART
Check the following.
- Harness connectors E6, F123
- Harness for open or short between PNP switch and ECM
Repair open circuit or short to ground or short to power in harness or connectors.
- CHECK PNP SWITCH
Refer to "COMPONENT INSPECTION (PARK/NEUTRAL POSITION SWITCH) ".
Is the inspection result normal?
YES: GO TO 6.
NO: Replace PNP switch.
- CHECK INTERMITTENT INCIDENT
Refer to "INTERMITTENT INCIDENT ".
