Check that the diode is fitted the right way
round (in accordance with the foolproofing
device).
Is the diode fitted the wrong way round?
Fit a diode the right way round in the correct
location in the passenger compartment fuse
box.
(see MR 411 Mechanical, 81C, Fuses,
Fuses: List and location of components)
A disconnected earth causes damage to
the fuse. If the diode and/or the fuse are
damaged, the tailgate earth (MYH) and the
passenger door earth (MAN and MAM)
should be checked.
If the earths are correct, replace the
diode and/or the fuse in the passenger
compartment fuse box (see MR 411
Mechanical, 81C, Fuses, Fuses: List and
location of components)Check the continuity of connection 86H between
components 1016 and 645.
If the connection or connections are faulty and there is
a repair procedure (see Technical Note 6015A,
Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If the wiring is in order, replace the driver's door switch

NOTESSpecial notes:
If the opening element motors are supplied too quickly and it is too difficult to test
using a multimeter, the measurements must be made using an oscilloscope.
No faults should be present or stored.
IMPORTANT
The door motors can perform 15 successive activations; beyond this there is a risk of the motors overheating and
being damaged.
NOTESNo faults should be present or stored.
Status ET463 “Door(s) or tailgate” must be “Open” when at least one of the
doors or tailgate is open and must be “Closed” when all of the doors and
tailgate are closed.
Note:
The tailgate lock (electric central door locking) must only be used to open the
luggage compartment and not to close it.
Check that fuses F14 (20 A) are sound and correctly fitted in the passenger compartment fuse and relay box
(for vehicles equipped with deadlocking function) (component code 1016).
Replace the fuse if necessary.
Check the condition and connection of the PE1, PE2 and PE3 connectors of the UCH (component code 645)
(tabs pushed back, oxidised, broken).
Check the condition and connection of the connectors of the electric locks of the driver's door (component
code 140), passenger door (component code 141) and the tailgate (component code 1322) (tabs pushed
back, oxidised, broken).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
