For A/T Models

CHECK PNP SWITCH POWER SUPPLY CIRCUIT-I
1. Turn ignition switch OFF.
2. Disconnect park/neutral position (PNP) relay.
3. Turn ignition switch ON.
4. Shift selector lever to P or N position.
5. Check voltage between PNP relay terminal 2 and engine ground with CONSULT-II or tester.
  Voltage: Battery voltage
OK or NG
1. OK: GO TO 6.
2. NG: GO TO 2.

CHECK PNP SWITCH POWER SUPPLY CIRCUIT-II
1. Turn ignition switch OFF.
2. Disconnect park/neutral position (PNP) switch harness connector.
3. Check harness continuity between PNP switch terminal 2 and PNP relay terminal 2. Refer to WIRING DIAGRAM .
  Continuity should exist.
4. Also check harness for short to ground and short to power.
OK or NG
1. OK: GO TO 3.
2. NG: Repair open circuit or short to ground or short to power in harness or connectors.

CHECK PNP SWITCH POWER SUPPLY CIRCUIT-III
1. Turn ignition switch ON.
2. Check voltage between PNP switch terminal 1 and engine ground with CONSULT-II or tester. Refer to WIRING DIAGRAM .
  Voltage: Battery voltage
OK or NG
1. OK: GO TO 5.
2. NG: GO TO 4.
DETECT MALFUNCTIONING PART
Check the following.
- Fuse block (J/B) connector E49
- 7.5A fuse
- Harness for open or short between PNP switch and fuse
  : Repair open circuit or short to ground or short to power in harness or connectors.
CHECK PARK/NEUTRAL POSITION (PNP) SWITCH
Refer to "PNP SWITCH ".

OK or NG
1. OK: GO TO 11.
2. NG: Replace park/neutral position (PNP) switch.
CHECK PNP RELAY GROUND CIRCUIT FOR OPEN AND SHORT
1. Turn ignition switch OFF.
2. Check harness continuity between PNP relay terminals 1, 6 and body ground. Refer to WIRING DIAGRAM .
  Continuity should exist.
3. Also check harness for short to power.
OK or NG
1. OK: GO TO 8.
2. NG (With vehicle security system): GO TO 7
3. NG (Without vehicle security system): Repair open circuit or short to power in harness or connectors.
DETECT MALFUNCTIONING PART
Check the circuit between PNP relay and body ground.

Refer to "STARTING/CHARGING " in SYSTEM WIRING DIAGRAMS.

OK or NG
1. OK: GO TO 11.
2. NG: Repair or replace.
CHECK PNP RELAY INPUT SIGNAL CIRCUIT FOR OPEN AND SHORT
1. Disconnect ECM harness connector.
2. Check harness continuity between ECM terminal 22 and PNP relay terminal 7. Refer to WIRING DIAGRAM .
  Continuity should exist.
3. Also check harness for short to ground and short to power.
OK or NG
1. OK: GO TO 10.
2. NG: GO TO 9.
DETECT MALFUNCTIONING PART
Check the following.
- Harness connectors F36, M81
- Harness connectors M65, E43
- Harness for open or short between ECM and park/neutral position (PNP) relay
  : Repair open circuit or short to ground or short to power in harness or connectors.
CHECK PARK/NEUTRAL POSITION (PNP) RELAY
1. Apply 12V direct current between park/neutral position (PNP) relay terminals 1 and 2.
2. Check continuity between park/neutral position (PNP) relay terminals 3 and 5, 6 and 7.
  12V (1 and 2) applied: Continuity should exist.
  
  No voltage applied: Continuity should not exist.
OK or NG
1. OK: GO TO 11.
2. NG: Replace park/neutral position (PNP) relay.
