Section 08 ENGINE MANAGEMENT (4-TEC)
Subsection 03 (DIAGNOSTIC PROCEDURES)
Electrical Connections
4-TEC Models Through the 6-Pin Connector
F12H0DA
1 2
TYPICAL
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.,
with the 4-TEC engines , ensure that the protocol
“kW2000” is properly selected in “ MPI ” under
“ Choose protocol ”.
When B.U.D.S. is connected with MPEM and
ECM, the status bar shows the protocol (kW2000)
and a number 1 or 2 to the right. To work with
the watercraft, number 2 must be displayed.
Number 2 means that 2 “ECUs” are connected
(MPEM and ECM).
F18H0XA
kW2000
MPEM AND ECM ARE CONNECTED
Number 1 means that 1 “ECU” is connected (ei-
ther MPEM or ECM). Therefore, there is a prob-
lem. Check fuses and connections.
F18H0WA
kW2000
ONLY ONE “ECU” IS WORKING. THERE IS A PROBLEM
If an “X” is shown, the safety lanyard is not in-
stalled on its post or there is a problem with both
“ECUs”. Ensure VCK is working properly and
check connections on VCK and watercraft.
VCK Supply
The VCK (MPI box) can use the watercraft power
for its supply.
The safety lanyard must be connected in order to
use the watercraft as a power source.
If watercraft power is used, every time the safety
lanyard is taken off the DESS post, the kW2000
protocol will have to be re-activated.
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 safety lanyard from
its post and wait until the message disappears
(it lasts approximately 15 seconds after lanyard
removal).
4-TEC SYSTEM FAULT CODES
General
The faults registered in the MPEM/ECM are kept
when the battery is disconnected.
IMPORTANT: After a problem has been solved,
ensure to clear the fault(s) in the MPEM/ECM us-
ing the VCK. This will properly reset the appropri-
ate counter(s). This will also records that the prob-
lem has been fixed in the MPEM/ECM 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.
