STOP AND START STOP AND START SYSTEM Engine Hood Courtesy Switch Circuit
DESCRIPTION
The engine stop and start ECU detects whether the engine hood is open or closed based on a signal received from the engine hood courtesy switch built into the hood lock assembly.
for Automatic Transmission:
The engine stop and start ECU prohibits starting of the engine by stop and start control and changes the mode to "stalled" if the engine hood is opened with the shift lever in D while the engine is stopped by stop and start control.
for Manual Transmission:
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.
