Control Module: Notes
The parking aid control module is located in the left hand rear quarter panel, behind the side trim panel. The control module uses a single microprocessor to perform the following tasks:
- Control of the ultrasonic sensors
- Monitoring of the sensors
- Evaluation of received echo signals from the sensors
- Noise and disturbance suppression
- Control of the parking aid sounders
- Monitoring of the sounders and associated wiring
- Control and monitoring of the switch status light emitting diode (LED) and associated wiring
- Evaluation and monitoring of the control inputs
- Management of diagnostic and test functions
- Monitoring of power supply
- Communication via diagnostic link.
The control module is connected to the vehicle electrical system by either 3 (vehicles fitted with front and rear sensors) or 2 (vehicles fitted with rear sensors only) multiplug connectors.
