Rear accelerometer replacement Op. 4440B52 BODY ACCELERATION SENSOR IN LUGGAGE COMPARTMENT - R.R.
7	COMPONENT CONCERNED	CHECK USING DIAGNOSTIC EQUIPMENT	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Rear left body accelerometer (signal not plausible)	Connect the diagnosis equipment to the controlled damping suspension control unit, delete the error memory then perform a key OFF/ON	Go to Step 9	Errors present	Go to Step 8
8	COMPONENT CONCERNED	ACCELEROMETER CALIBRATION CHECK	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Rear left body accelerometer (signal not plausible)	Keep the diagnosis equipment connected and calibrate the accelerometers.	Go to Step 9	Procedure failed	Rear accelerometer replacement Op. 4440B52 BODY ACCELERATION SENSOR IN LUGGAGE COMPARTMENT - R.R.
9	COMPONENT CONCERNED	CHECK WHETHER THE FAULT PERSISTS	OK (NO FAULTS DETECTED)	FAULT DETECTED	OPERATION
	Rear left body accelerometer (signal not plausible)	Check whether the fault persists	End of diagnosis	Fault persists	After restoring the replaced accelerometer, replace the controlled damping suspension control unit Op. 4440B10 INTELLIGENT SUSPENSION SYSTEM CONTROL UNIT - R.R.
