AUTOMATIC TRANSAXLE SYSTEM Pattern Select Switch Sport Mode Circuit

DESCRIPTION

The ECM memory contains the programs for the normal and sport shift patterns.

By following the programs corresponding to the signals from the integration control & panel assembly (pattern select switch), park/neutral position switch and other various sensors, the ECM switches the shift solenoid valves on and off, and controls the transaxle gear ratio.

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

      Standard Resistance
      Tester Connection Switch Condition Specified Condition
      7 (P) - 1 (GND) Pattern select switch being turned and held at SPORT position Below 1 Ω
      7 (P) - 1 (GND) Pattern select switch not turned 10 kΩ or higher
      8 (B) - 1 (GND) Pattern select switch being pushed and held Below 1 Ω
      8 (B) - 1 (GND) Pattern select switch not pushed 10 kΩ or higher
      Result
