MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch assembly and the wire harness in the park/neutral position switch assembly circuit.
The park/neutral position switch assembly detects the shift lever position and sends signals to the ECM.
For safety, the park/neutral position switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The park/neutral position switch assembly sends a signal to the ECM according to the shift lever position (P, R, N, D or S). 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

NOTICE:
  1. Inspect the fuses for circuits related to this system before performing the following inspection procedure.
  2. Perform registration and/or initialization when parts related to the automatic transmission are replaced (LandCruiser RM000000O7H0HSX.html).
HINT:
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
  1. Turn the engine switch on (IG).*1
  2. Wait with the shift lever in each position (P, R, N and D) for 60 seconds or more.*2
  3. Wait for 2 seconds or more with the shift lever in S.*3
  4. Turn the engine switch off.
  5. Perform steps (*1) through (*3) again.
  6. Check for DTCs again (LandCruiser RM000000W7711KX.html).

DATA LIST
HINT:
Using the GTS to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.
NOTICE:
In the table below, 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.

  1. Warm up the engine.

  2. Turn the engine switch off.

  3. Connect the GTS to the DLC3.

  4. Turn the engine switch on (IG).

  5. Turn the GTS on.

  6. Enter the following menus: Powertrain / Engine and ECT / Data List.

  7. According to the display on the GTS, read the Data List.
