AUTOMATIC TRANSMISSION SYSTEM A/T P Indicator Circuit

DESCRIPTION

The propeller shaft and wheels are free even when the transmission shift lever is on P, as long as the transfer shift lever is on N. The A/T P indicator illuminates to warn the driver that the propeller shaft and wheels are not locked.

If the A/T P indicator illuminates, the transfer shift lever should be moved from N.

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK WIRE HARNESS (NO. 2 TRANSFER INDICATOR SWITCH - BODY GROUND)


    1. A01DZTBE05

      Disconnect the T5 switch connector.

    2. Measure the resistance of the wire harness side connector.

      Standard resistance
      Tester Connection Condition Specified Condition
      T5-2 - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK

  2. INSPECT NO. 2 TRANSFER INDICATOR SWITCH (TRANSFER NEUTRAL POSITION SWITCH)


    1. A01E01JE12

      Remove the transfer indicator switch.

    2. Measure the resistance of the switch when pushing the ball at the tip of the switch.

      Standard resistance
      Tester Connection Switch Condition Specified Condition
      1 - 2 Not pushed 10 kΩ or higher
      1 - 2 Pushed Below 1 Ω

    NG

    REPLACE NO. 2 TRANSFER INDICATOR SWITCH

    OK

  3. CHECK WIRE HARNESS (NO. 2 TRANSFER INDICATOR SWITCH - ECM)


    1. A01DZKKE02

      Disconnect the T5 switch connector.

    2. Disconnect the E9 ECM connector.

    3. Measure the resistance of the wire harness side connectors.

      Standard resistance
      Tester Connection Condition Specified Condition
      E9-23 (TFN) - T5-1 Always Below 1 Ω
      E9-23 (TFN) or T5-1 - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS AND CONNECTOR

    OK

    REPLACE ECM
