For manual gearbox:
●Connection code 86H between components 140 or 141 and 645.
For sequential gearbox:
●Connection code H24 between components 140 and 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the supplies and connections of the electric central door and tailgate locking are correct, check the central door
locking relay.
Check the insulation of the contact of component 140 between connections 86H and MAM (door closed).
Check the continuity of the contact of component 140 between connections 86H and MAM (door open).
Check the insulation of the contact of component 141 between connections 86H and MAM (door closed).
Check the continuity of the contact of component 141 between connections 86H and MAM (door open).
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the supply, connections and earth of the central door locking relay are correct, replace the relay.
If the supplies, central door locking connections, locking relay and electric central door locking relay are correct,
replace the lock concerned.

Check the insulation, continuity and the absence of interference resistance of the following connections:
Central door locking/warning switch check (component code 1391):
●Connection code 20AW between components 645 and 1391.
●Connection code 20M between components 645 and 1391.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the connections are correct, replace the central door locking/warning switch (component code 1391).
(See MR 411 Mechanical 84A, Control - Signals, Hazard warning lights and central door locking:
Removal - Refitting).
With the engine running, check that the door
open warning (buzzer) is active when the driver
door is open and the lights are on.
Is the warning active?
NO
Check the continuity of connection H24 between

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.
