STOP AND START SYSTEM(for 2WW) Engine Hood Courtesy Switch Circuit

DTC Code DTC Name
Engine Hood Courtesy Switch Circuit

DESCRIPTION

The engine stop and start ECU detects open/close of the engine hood based on a signal received from the engine hood courtesy switch that is built into the hood lock assembly.

  • The engine stop and start ECU prohibits starting of the engine by stop and start control and stalls the engine if the clutch pedal is depressed with the engine hood open while the engine is stopped by stop and start control.

  • The engine stop and start ECU permits starting of the engine by stop and start control if the engine hood is opened with the clutch pedal depressed while the engine is stopped by stop and start control.
