PGM-FI
NOTICE
If the MIL indicator comes on while driving, you may
have a problem with the PGM-FI electronic injection sys-
tem.
Slow down and stop the motorcycle in a safe place.
Re-start the motorcycle.
If the MIL indicator is still on after 5 seconds, inspect the
motorcycle at your Montesa dealer as soon as possible.
OBD system (diagnosis system)
This motorcycle complies with the Euro 4 standard and
with the OBD diagnosis system phase1. The existing
PGM-FI injection system is equipped with a self-diagnosis
system. When there is an anomaly in the injection sys-
tem, the engine control module (ECM) turns on the engine
trouble indicator (MIL) and stores an error code (DTC) in
its memory. With the OBD diagnosis system, a generic
diagnostic tool (DST) available in shops can be connected
to consult and clear the DTC error codes and the frozen
data.
(1) 4P OBD (RED) (4) OBD CONNECTOR
(2) 4P CONNECTOR (5) DST
(3) 16P CONNECTOR
Connection of a generic diagnosis tool (DST)
The DTC error codes read by the generic diagnostic tool
(DST), follow the format of the ISO standard and the con-
nector of the DST is also the 16-pin of the ISO standard.
Therefore, in order to connect the generic diagnosis tool
(DST) to the motorcycle, it is necessary to use an adapter
(reference 070MZ-K530101) for the 4-pin OBD connector
(red), which is located behind the headlight housing.
To use the DST, refer to the instruction manual included
with the purchased model.
Connect the diagnostic tool (DST) as shown in the
illustration and start the motorcycle.
Check the active DTC codes and confirm the error code
in the code list on page “MIL and DTC (ISO) error codes
of the PGM-FI electronic injection system” on page 6-9.
Stop the motorcycle and solve the fault.
Start the motorcycle and with the help of the DST proceed
to erase the fault codes stored in the speedometer.
Once the speedometer failure codes have been eliminated
with the DST, even if it is not necessary, it is recommended
to also delete the codes stored in the ECM (see page 6-7).
Fail-safe function
The PGM-FI system is provided with a fail-safe function to
secure a minimum running capability even when there is
trouble in the system. When any abnormality is detected
by the self-diagnosis function, running capability is main-
tained by pre-programmed value in the simulated program
map. When any abnormality is detected in the injector,
the fail-safe function stops the engine to protect it from
damage.
MIL Check
When the engine is started the MIL will stay on for 5
seconds and then go off. If the MIL does not come off,
troubleshoot DTC code. If the MIL does not come on,
troubleshoot the MIL circuit.
