AUTOMATIC TRANSMISSION SYSTEM(for 1VD-FTV) Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The ECM memory contains the programs for the normal and sport shift patterns and lock-up pattern.

By following the programs corresponding to the signals from the SPORT S/S+ switch (integration control and panel assembly), the park/neutral position switch and other various sensors, the ECM switches the solenoid valves on and off, and controls the transmission gear change and the lock-up clutch operation.

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

      Standard Resistance
      for LHD:
      Tester Connection Switch Condition Specified Condition
      3 (P) - 5 (E) SPORT S/S+ switch on Below 1 Ω
      2 (B) - 5 (E) NORM switch on Below 1 Ω
      3 (P) - 5 (E) SPORT S/S+ switch off 10 kΩ or higher
      2 (B) - 5 (E) NORM switch off 10 kΩ or higher
      for RHD:
      Tester Connection Switch Condition Specified Condition
      6 (P) - 5 (E) SPORT S/S+ switch on Below 1 Ω
      2 (B) - 5 (E) NORM switch on Below 1 Ω
      6 (P) - 5 (E) SPORT S/S+ switch off 10 kΩ or higher
      2 (B) - 5 (E) NORM switch off 10 kΩ or higher
