Section 04 ENGINE MANAGEMENT SYSTEM
Subsection 02 (COMMUNICATION TOOLS/B.U.D.S. SOFTWARE)
NOTE: Number 2 means that 2 “ECU” are con-
nected (ECM and multifunction gauge).

CONNECTION SUCCESSFUL
Transfer data from the ECM to B.U.D.S. by clicking
the
Read Data button in B.U.D.S.
vmr2006-012-100_aen
When finished, transfer data from B.U.D.S. to the

vmr2006-012-100_ben
Disconnect MPI connections and reconnect vehi-
cle harness in protective cap.
NOTE: There is a 120 resistor in protective cap
to minimize the possibility of communication error.
Changes in ECM
Anytime a change is brought in ECM through
B.U.D.S., there will be an “EMS Tracking” mes-
sage that will say “Remove key from vehicle”.
When this occurs, remove the key from ignition
switch and wait until the message disappears
(it lasts approximately 30 seconds after key re-
moval).
Communication Problems
If an “X” is shown, this means there is no com-
munication between the MPI and the ECM or the
multifunction gauge.
mmr2009-020-001
The possible causes are:
– Wrong protocol is used.
– Both ECM and multifunction gauge are not
communicating with the MPI.
NOTE: If a “1” is shown, either the ECM or the
multifunction gauge is not communicating with
the MPI.
