REPLACING THE HIGH PRESSURE PUMP
aIf replacing the high pressure pump, reprime the die-
sel circuit using the Diagnostic tool.
aConnect the Diagnostic tool to the vehicle.
aConnect to the diesel injection computer.
aRun command AC212 « NEW PUMP CHAMBER
FILLING » (see Fault finding - Replacement of
components) (13B, Diesel injection).
aFollow the instructions on the Diagnostic tool until
the command is completed.
aStart the engine.
aIf the engine does not start or if the startup sequence
is interrupted:
-switch off the ignition,
-wait 30 seconds,
-restart the engine.
aUsing the Diagnostic tool, clear any faults stored in
the diesel injection computer.Note:
Never start the engine until the pump has been
reprimed.
Also comply with the operation instructions pro-
vided to prevent the high pressure pump from
being damaged internally, due to running with no
load and no diesel lubrication.
Note:
The starting phase may last up to 20 seconds.

WARNING
Before fitting a new high pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high pressure
pipe.
Do not lubricate high pressure pipes supplied
without an applicator, as these high pressure
pipes are self-lubr icating.
