AUTOMATIC TRANSMISSION SYSTEM (for 1GR-FE) Transmission Control Switch Circuit

DESCRIPTION

After moving the shift lever to S, it is possible to switch the shift range between "1" (S1 range) and "5" (S5 range) using the transmission control switch.

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

   INSPECT TRANSMISSION CONTROL SWITCH

   
   
   1. 

      Disconnect the G47 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

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

   
   
   1. 

      Disconnect the G47 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 G47-3 (IG) - Body ground Ignition switch ON 11 to 14 V G47-3 (IG) - Body ground Ignition switch off Below 1 V

   3. Turn the ignition switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition G47-5 (E) - Body ground Always Below 1 Ω

   CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)

   
   
   1. 

      Disconnect the G56 ECM connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition G56-24 (S) - Body ground Ignition switch ON Shift lever in S, "+" or "-" 11 to 14 V G56-24 (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
      Tester Connection Condition Specified Condition G56-16 (SFTU) - Body ground Shift lever held in "+" (Up-shift) Below 1 Ω G56-22 (SFTD) - Body ground Shift lever held in "-" (Down-shift) Below 1 Ω G56-16 (SFTU) - Body ground Shift lever in S 10 kΩ or higher G56-22 (SFTD) - Body ground Shift lever in S 10 kΩ or higher
