ELECTRONIC SHIFT LEVER SYSTEM P Position Switch Indicator Circuit

DESCRIPTION

The P position switch (shift position indicator) ON (indicator illuminates (shift state park (P))) or OFF (indicator goes off (shift state other than park (P))) is displayed.

The P position switch indicator goes off when a system malfunction occurs (not in all cases) and a warning message will also be displayed on the multi-information display.

PROCEDURE


  1. CHECK P POSITION SWITCH (SHIFT POSITION INDICATOR) (INDICATOR STATUS)


    1. Turn the power switch on (IG).

    2. Depress the brake pedal and move the shift lever to select neutral (N).

    3. Operate the P position switch (shift position indicator) and check the condition of the indicator.

      Result
      Condition of Indicator Proceed to
      Indicator does not go off. (Remains on) A
      Indicator does not come on. B

    4. Turn the power switch off.

  2. CHECK P POSITION SWITCH (SHIFT POSITION INDICATOR) (CHECK ILLUMINATION)


    1. Disconnect the P75 shift control ECU connector.

    2. Turn the power switch on (IG).

    3. Inspect the P position switch indicator condition.

      Result
      Result Proceed to
      Indicator illuminates A
      Indicator goes off. B

      Note

      Turning the power switch on (IG) with the shift control ECU connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    4. Turn the power switch off.

    5. Reconnect the P75 shift control ECU connector.

  3. CHECK HARNESS AND CONNECTOR (SHIFT CONTROL ECU - P POSITION SWITCH (SHIFT POSITION INDICATOR))


    1. Disconnect the P75 shift control ECU connector.

    2. Disconnect the P39 P position switch (shift position indicator) connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      P75-12(INDP) or P39-6(P) - Body ground and other terminals Always 10 kΩ or higher

    4. Reconnect the P39 P position switch (shift position indicator) connector.

    5. Reconnect the P75 shift control ECU connector.

      (to P Position Switch (Shift Position Indicator))

      Disconnect the P position switch (shift position indicator) connector.

    2. Turn the power switch on (IG).

    3. Measure the voltage according to the value(s) in the table below.

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      P39-5(PWR) - Body ground Power switch on (IG) 9 to 14 V

      Note

      Turning the power switch on (IG) with the connector disconnected causes other DTCs to be stored. Clear the DTCs after performing this inspection.

    4. Turn the power switch off.

    5. Reconnect the P position switch (shift position indicator) connector.
