CRUISE CONTROL SYSTEM(except 1ND-TV, 8NR-FTS) Clutch Switch Circuit

DESCRIPTION

While depressing the clutch pedal, the No. 2 clutch pedal switch sends a signal to terminal (D) of the ECM. The ECM cancels cruise control when terminal (D) receives the signal.

      Tester Connection Condition Specified Condition
      B164-73 (D) - A4-2 (CL-) Always Below 1 Ω
      Standard Resistance (Check for Short)
      for 1NR-FE, 1ZR-FAE, 1ZR-FE, 2ZR-FE
      Tester Connection Condition Specified Condition
      B31-81 (D) or A4-2 (CL-) - Body ground Always 10 kΩ or higher
      for 1AD-FTV
      Tester Connection Condition Specified Condition
      B164-73 (D) or A4-2 (CL-) - Body ground Always 10 kΩ or higher
