Central locking On Board Diagnostic (OBD)
Central locking On Board
Diagnostic (OBD)
General Information
The new generation of central locking is capable
of On Board Diagnostic. Use of DTC memory,
Output Diagnostic Test Mode and Read
Measuring Value Block facilitates the search for
malfunctions. The central locking system
variation can also be coded using the VAG1551
Scan Tool (ST).
Central locking has two pneumatic circuits. For
central locking without keyless entry, the first
circuit controls only the fuel filler flap; for central
locking with the keyless entry system, the first
circuit controls both the fuel filler flap and the
driver-side door. The second circuit controls all
remaining locking points.
On the safety-version of central locking, if the
driver-side (or passenger-side door) is unlocked
with a single command, then only that door and
the first pneumatic circuit are opened. If there is
another unlocking command within 5 seconds,
the second pneumatic circuit is also triggered
and the whole vehicle is unlocked.
If the rear lock cylinder is triggered only once, all
doors will remain locked. The rear lid (or tailgate)
will automatically re-lock itself after about 5
seconds.
Central locking On Board Diagnostic (OBD)
until fully illuminated (within about 1.5 seconds)
when unlocking (fades off when locking).
Central locking On Board Diagnostic (OBD)
The control of the luggage compartment lighting
proceeds from the central locking pump to the
rear lid (or tailgate) contact switch. The lighting
will be switched off while the rear lid is open
when a certain speed threshold is surpassed
(about 5 km/h) or after 10 minutes.
The new remote transmitter now uses radio
frequency. For vehicles using the radio frequency
remote locking system, the receiver is integrated
into the central locking pump. The remote locking
antenna is integrated into the wiring harness.
If no doors (or the rear lid) have been opened
within 60 seconds after the central locking
system is triggered via radio frequency, central
locking automatically relocks everything.
If the anti-theft alarm system is armed, central
locking cannot be opened via internal buttons.
All vehicles with an anti-theft system are
equipped with an ultrasonic interior monitoring
system. This could be an interior monitor of the
1st generation (without OBD) or of the 2nd
generation (with OBD). All that is necessary is
the proper coding of the central locking system
page 01-91 .
Confirmation can be received from central
locking as to whether the alarm system has been
armed while locking the doors. The confirmation
can be signalled by means of a short anti-theft
Central locking On Board Diagnostic (OBD)
emergency flashers. Central locking can also be
coded to give no confirmation at all.
Activation of keyless entry can be signalled by a
flashing of the emergency flashers.
