Circuit Description
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.
Clutch switch circuit inspection is necessary for M/T vehicle.
When the clutch pedal is released, the ECM receive positive (+) battery voltage through the IG1 Relay and GAUGE1 fuse. While depressing the clutch pedal, the clutch switch assy sends a signal to terminal D of the ECM. The ECM cancels cruise control drive when terminal D receives the signal (voltage of below 1 V).
