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.

PROCEDURE


  1. INSPECT TRANSMISSION CONTROL SWITCH


    1. B00203TE06
      *1 Component without harness connected: (Transmission Control Switch)

      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

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


    1. A01X4RZE01
      *1 Front view of wire harness connector: (to Transmission Control Switch)

      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

    OK

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


    1. A01X5CME01

      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
