Inspection Procedure

WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT CRUISE CONTROL MAIN SWITCH 
    1. Turn the ignition switch off.
    2. Disconnect the cruise control main switch connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard: 

      SWITCH CONDITION

      Tester connection Switch condition Specification
      1 -3 + /RES 235 to 245 Ω
      1 -3 -/SET 617 to 643 Ω
      1 -3 CANCEL 1,509 to 1,571 Ω
      1 -3 Main Switch OFF 10 kΩ or higher
      1 -3 Main Switch ON Below 1 Ω
