DESCRIPTION
Clutch switch circuit inspection is necessary for manual transmission vehicles.
When the clutch pedal is released, the ECM receives the positive (+) battery voltage through the ECU-IG NO. 2 fuse and ignition switch. While the clutch pedal is depressed, the clutch switch assembly sends a signal to terminal D of the ECM. The ECM cancels cruise control when terminal D receives the signal (voltage of below 1 V).

Theft Deterrent System Unexpectedly Sets Itself
DESCRIPTION
A situation in which the theft deterrent system unexpectedly sets itself can
be caused when the main body ECU (multiplex network body ECU) cannot detect whether
a door is open or closed.
If the theft deterrent system unexpectedly sets itself, there may be a malfunction
in a court ...
