СИСТЕМА АВТОМАТИЧЕСКОЙ ТРАНСМИССИИ 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. 

      *a	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

      Result
      Proceed to OK NG

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

   
   
   1. 

      *a	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 G36-3 (IG) - Body ground Engine switch on (IG) 11 to 14 V G36-3 (IG) - Body ground Engine switch off Below 1 V

   3. Turn the engine switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition G36-5 (E) - Body ground Always Below 1 Ω

      Result
      Proceed to OK NG

   CHECK HARNESS AND CONNECTOR (TRANSMISSION CONTROL SWITCH - ECM)

   
   
   1. 

      *a	Rear view of wire harness connector (to ECM)

      Disconnect the ECM connector.

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

      Standard Voltage
      Tester Connection Condition Specified Condition G107-24 (S) - Body ground Engine switch on (IG) Shift lever in S, "+" or "-" 11 to 14 V G107-24 (S) - Body ground Engine switch on (IG) Shift lever not in S, "+" or "-" Below 1 V

   3. Turn the engine switch off.

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

      Standard Resistance
      Tester Connection Condition Specified Condition G107-16 (SFTU) - Body ground Shift lever held in "+"(Up-shift) Below 1 Ω G107-22 (SFTD) - Body ground Shift lever held in "-"(Down-shift) Below 1 Ω G107-16 (SFTU) - Body ground Shift lever in S 10 kΩ or higher G107-22 (SFTD) - Body ground Shift lever in S 10 kΩ or higher

      Result
      Proceed to OK NG
