1. 6-pin adapter
2. Connector close to MPEM
After all connections are done, connect the safety
lanyard to the DESS post to activate the commu-
nication.
IMPORTANT: When using the software B.U.D.S.,
ensure that the protocol matching the connec-
tion used is properly selected in “MPI” under
“Choose protocol” as per the following chart.

IMPORTANT: When using the software B.U.D.S.,
with the DI engines, ensure that the protocol “947
DI” is properly selected in “MPI” under “Choose
protocol”.
Refer to the tables below for the fault codes you
will find in the B.U.D.S.
DI SYSTEM FAULT CODES
General
The faults registered in the MPEM are kept when
the battery is disconnected.
Be aware that a red light blinking with the MAINT
message may not be for a fault code. It may be a
maintenance inspection reminder. Press and hold
the SET button of the information center for 2 sec-
onds. If the blinking continues, it is a fault code.
Use the VCK (Vehicle Communication Kit) to see
it. Otherwise, it was a maintenance reminder.
IMPORTANT: After a problem has been solved,
ensure to clear the fault(s) in the MPEM using
the VCK. This will properly reset the appropriate
counter(s). This will also records that the problem
has been fixed in the MPEM memory.
Many fault codes at the same time is likely to be
burnt fuse(s).
For more information pertaining to the code
faults (state, count, first etc.) and report, refer to
B.U.D.S. online help.
Supplemental Information for
Some Specific Faults
ECU fault code P0606: This code may occur in
the following situations:
– Electrical noise is picked up by the MPEM. En-
sure that all connections are in good condition,
also grounds (battery, MPEM, engine and igni-
tion system), they are clean and well tightened
and that all electronic components are genuine
-- particularly in the ignition system. Installing
resistive caps, non-resistive spark plug cables
(or modified length), non-resistive spark plugs
or improper knock sensor wiring/routing may
lead to generate this fault code.
– Electrical noise might also lead engine to oc-
casional cutout without generating a fault code
when engine is restarted. When looking at the
fault code, pay attention to the “count” value in
the software B.U.D.S. A value between 1 and
9 confirms an electrical noise problem. A value
of 10 and above will generate a fault code.
– When installing a new MPEM. It is not proper-
ly programmed from the factory. The MPEM
must be returned to be properly “activated”.
– If everything is in good condition, replace the
MPEM.
When using the service action suggested in the
Fault section of B.U.D.S., the system circuits are
referred as 4-23 for instance. It means AMP con-
nector no. 4 and the circuit wire no. 23 as found
in the wiring diagram.
