ELECTRONIC SHIFT LEVER SYSTEM, Diagnostic DTC:P085011, P085015

DTC Code DTC Name
P085011 Park/Neutral Switch Circuit Short to Ground
P085015 Park/Neutral Switch Circuit Short to Battery or Open

DESCRIPTION

Instead of having a parking position as one of the positions as on a conventional shift lever, a P position switch (shift position indicator) is provided independently under the shift lever. The switch is a momentary type, in which the button does not lock mechanically.

The P position switch (shift position indicator) contains resistors R1, R2, R3 and R4. When the P position switch (shift position indicator) is not pressed, the switch provides a combined resistance of R3 and R4; and when the P position switch (shift position indicator) is pressed, the switch provides a combined resistance of R1, R2, R3 and R4. The voltage at the P1 terminal of the shift control ECU varies with the changes in the resistance of the switch. The shift control ECU determines the P position switch (shift position indicator) operation according to this resistance signal.

PROCEDURE


  1. INSPECT P POSITION SWITCH (SHIFT POSITION INDICATOR)


    1. B000Z4WC04
      *a

      Component without harness connected

      (P Position Switch (Shift Position Indicator))

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

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      14 (S) - 12 (E) Switch being pressed 613 to 751 Ω
      14 (S) - 12 (E) Switch released 3.9 to 4.9 kΩ

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

      Result
      Proceed to
      OK
      NG

    NG

    REPLACE P POSITION SWITCH (SHIFT POSITION INDICATOR)

    OK

  2. 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 Open)
      Tester Connection Condition Specified Condition
      P75-10 (P1) - P39-14 (S) Always Below 1 Ω
      Standard Resistance (Check for Short)
      Tester Connection Condition Specified Condition
      P75-10 (P1) or P39-14 (S) - 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.

      Result
      Proceed to
      OK
      NG

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK HARNESS AND CONNECTOR (P POSITION SWITCH (SHIFT POSITION INDICATOR) - BODY GROUND)


    1. B000X0AC05
      *a

      Front view of wire harness connector

      (to P Position Switch (Shift Position Indicator))

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

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

      Standard Resistance (Check for Open)
      Tester Connection Condition Specified Condition
      P39-12 (E) - Body ground Always Below 1 Ω
