MONITOR DESCRIPTION
These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/neutral position switch circuit.The park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that the engine can be started only when the shift lever is on P or N.
The park/neutral position switch sends a signal to the ECM according to the shift lever position (R, D, 4, 3, 2 or L).
The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The ECM will illuminate the MIL and store the DTC.

INSPECTION PROCEDURE
- HINT:
- Using the intelligent tester's Data List allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the Data List early in troubleshooting is one way to save time.
- Warm up the engine.
- Turn the ignition switch OFF.
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch ON and push the tester main switch ON.
- Enter the following menus: Powertrain / Engine and ECT / Data List.
- Follow the instructions on the tester and read the Data List.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
| Neutral Position SW Signal | PNP switch status/ ON or OFF | Shift lever is: In P or N: ON Not in P or N: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (L Range) | PNP switch status/ ON or OFF | Shift lever is: In L: ON Not in L: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (2 Range) | PNP switch status/ ON or OFF | Shift lever is: In 2: ON Not in 2: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (3 Range) | PNP switch status/ ON or OFF | Shift lever is: In 3: ON Not in 3: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (4 Range) | PNP switch status/ ON or OFF | Shift lever is: In 4: ON Not in 4: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (R Range) | PNP switch status/ ON or OFF | Shift lever is: In R: ON Not in R: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
| Shift SW status (D Range) | PNP switch status/ ON or OFF | Shift lever is: In D: ON Not in D: OFF | When the shift lever position displayed on the intelligent tester differs from the actual position, the adjustment of the PNP switch or shift cable may be incorrect. |
- CAUTION:
- In the table above, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.
- HINT:
- When the malfunction is found when the shift lever is on 3, start from *1. When the malfunction is found when the shift lever is not on 3, start from *2.
| 1.INSPECT PARK/NEUTRAL POSITION SWITCH*1 |
Disconnect the N1 park/neutral position switch connector.
 |
Measure the resistance of the park/neutral position switch when the shift lever is moved to each position.
- Standard resistance:
Tester Connection Shift Lever Position Specified Condition 4 (B) - 5 (L) P or N Below 1 Ω 4 (B) - 5 (L) Not on P or N 10 kΩ or higher 1 (RL) - 2 (RB) R Below 1 Ω 1 (RL) - 2 (RB) Not on R 10 kΩ or higher 2 (RB) - 7 (DL) D Below 1 Ω 2 (RB) - 7 (DL) Not on D 10 kΩ or higher 2 (RB) - 3 (2L) 2 Below 1 Ω 2 (RB) - 3 (2L) Not on 2 10 kΩ or higher 2 (RB) - 8 (LL) L Below 1 Ω 2 (RB) - 8 (LL) Not on L 10 kΩ or higher

| OK | |
| 2.INSPECT SHIFT LOCK CONTROL ECU*2 |
Disconnect the S11 ECU connector.
 |
Measure the resistance of the ECU when the shift lever is moved to each position.
- Standard resistance:
Tester Connection Shift Lever Position Specified Condition 9 (NSSD) - 3 (AT4) D 10 kΩ or higher 9 (NSSD) - 3 (AT4) 3 Below 1 Ω 10 (NSSL) - 4 (ATL) 2 10 kΩ or higher 10 (NSSL) - 4 (ATL) L Below 1 Ω

| OK | |
| 3.CHECK WIRE HARNESS (ECM - BATTERY AND BODY GROUND) |
 |
Turn the ignition switch ON.
Measure the voltage of the wire harness side connectors.
- Standard voltage:
Tester Connection Shift Lever Position Specified Condition E13-11 (R) - Body ground R 11 to 14 V* E13-11 (R) - Body ground Not on R Below 1 V E13-21 (D) - Body ground D or 3 11 to 14 V E13-21 (D) - Body ground Not on D or 3 Below 1 V E13-19 (3) - Body ground 3 11 to 14 V E13-19 (3) - Body ground Not on 3 Below 1 V E13-10 (2) - Body ground 2 11 to 14 V E13-10 (2) - Body ground Not on 2 Below 1 V E13-9 (L) - Body ground L 11 to 14 V E13-9 (L) - Body ground Not on L Below 1 V
- HINT:
- *: The voltage will drop slightly due to the illumination of the back-up light.
