Title: STOP AND START: STOP AND START SYSTEM: Engine Hood Courtesy Switch Circuit; 2024 MY RAV4 [10/2023 -        ]

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.

  • 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.
