BOOT OPENING NOT WORKING USING REMOTE CONTROL

The boot lid does not open when the remote control is operated.

The boot lid opening command is received by the Body Computer Node via the internal RF receives; the Body Computer Node sends the command, via the B-Can, to the luggage compartment node which releases the lock disabling the alarm (if fitted).

With the "central locking switched off", the boot lid opens activating the electric handle located on the actual boot lid.

In "indepedent boot" mode, the opening of the boot lid is implemented using the remote control or by means of the mechanical key pawl.

STEP	OPERATIONS TO BE CARRIED OUT	TEST RESULTS
0	PRELIMINARY CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check the charge of the remote control battery.	Move on to Step	Battery not properly charged.	Replace the remote control battery.
1	PRELIMINARY CHECK	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Check the operation of the system using the second remote control.	Move on to Step	The fault persists.	Move on to Step
2	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment and check: no faulty control units no control units with faulty CAN line; no control units inactive;	Move on to Step	Faulty control units present	Continue following the instructions in the diagnostic table
3	CHECK USING DIAGNOSTIC EQUIPMENT	ALL OK	PROBLEMS ENCOUNTERED	ACTION
	Connect the Examiner diagnostic equipment and check that the "defective" remote control is correctly programmed inside the Body Computer Node configuration.	Move on to Step	Remote control not stored in Body Computer Node configuration.	Programme the remote control (see Description and Operation).
