AUTOMATIC TRANSMISSION SYSTEM (for 1VD-FTV) Transmission Control Switch Circuit

DESCRIPTION

When moving the shift lever to S using the transmission control switch, it is possible to switch the shift range between "1" (1st range) and "6" (6th range).

Shifting to "+" once raises the shift range by one, and shifting to "-" lowers the shift range by one.

INSPECTION PROCEDURE

PROCEDURE


  1. INSPECT TRANSMISSION CONTROL SWITCH


    1. A0157EQE06

      Disconnect the transmission control switch connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      3 (IG) - 7 (S) Shift lever in S, "+" or "-" Below 1 Ω
      2 (SFTU) - 5 (E)

      Shift lever held in "+"

      (Up-shift)

      		 Below 1 Ω
      1 (SFTD) - 5 (E)

      Shift lever held in "-"

      (Down-shift)

      		 Below 1 Ω
      3 (IG) - 7 (S) Shift lever not in S, "+" or "-" 10 kΩ or higher
      2 (SFTU) - 5 (E) Shift lever in S 10 kΩ or higher
      1 (SFTD) - 5 (E) Shift lever in S 10 kΩ or higher

    NG

  2. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - BATTERY, BODY GROUND)


    1. A015CXKE14

      Disconnect the transmission control switch connector.

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

      Standard Voltage
      Tester Connection Switch Condition Specified Condition
      E52-3 (IG) - Body ground Ignition switch ON 11 to 14 V
      E52-3 (IG) - Body ground Ignition switch off Below 1 V

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      E52-5 (E) - Body ground Always Below 1 Ω

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK

  3. CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)


    1. A0158QYE14

      Disconnect the ECM connector.

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

      Standard Voltage
      for LHD
      Tester Connection Condition Specified Condition
      A38-25 (S) - Body ground

      • Ignition switch ON

      • Shift lever in S, "+" or "-"

      		 11 to 14 V
      A38-25 (S) - Body ground

      • Ignition switch ON

      • Shift lever not in S, "+" or "-"

      		 Below 1 V
      for RHD
      Tester Connection Condition Specified Condition
      A52-25 (S) - Body ground

      • Ignition switch ON

      • Shift lever in S, "+" or "-"

      		 11 to 14 V
      A52-25 (S) - Body ground

      • Ignition switch ON

      • Shift lever not in S, "+" or "-"

      		 Below 1 V

    3. Turn the ignition switch off.

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

      Standard Resistance
      for LHD
      Tester Connection Condition Specified Condition
      A38-60 (SFTU) - Body ground

      Shift lever held in "+"

      (Up-shift)

      		 Below 1 Ω
      A38-59 (SFTD) - Body ground

      Shift lever held in "-"

      (Down-shift)

      		 Below 1 Ω
      A38-60 (SFTU) - Body ground Shift lever in S 10 kΩ or higher
      A38-59 (SFTD) - Body ground Shift lever in S 10 kΩ or higher
      for RHD
      Tester Connection Condition Specified Condition
      A52-60 (SFTU) - Body ground

      Shift lever held in "+"

      (Up-shift)

      		 Below 1 Ω
      A52-59 (SFTD) - Body ground

      Shift lever held in "-"

      (Down-shift)

      		 Below 1 Ω
