CRUISE CONTROL SYSTEM (except 1WW) Clutch Switch Circuit

DESCRIPTION

While depressing the clutch pedal, the clutch switch sends a signal to terminal 47 (D)*1 or 73 (D)*2 of the ECM. The ECM cancels cruise control when terminal 47 (D)*1 or 73 (D)*2 receives the signal.

*1: for ZR Series Engine

*2: for AD Series Engine
