PGM-FI SYSTEM
MIL BLINK PATTERN
• If the MCS is not available, DTC can be read from the ECM memory by the MIL blink pattern.
• The number of MIL blinks is the equivalent to the main code of the DTC (the sub code cannot be displayed by the MIL).
• The MIL will blink the current DTC, in case the ECM detects the problem at present, when the ignition switch is turned ON with
the engine stop switch " " or idling with the sidestand down. The MIL will stay ON when the engine speed is over 1,800 min
(rpm) or with the sidestand up.
• The MIL has two types of blinks, a long blink and short blink. The long blinking lasts for 1.3 seconds, the short blinking lasts for
0.3 seconds. One long blink is the equivalent of ten short blinks. For example, when two long blinks are followed by nine short
blinks, the DTC is 29 (two long blinks = 20 blinks, plus nine short blinks).
• When the ECM stores more than one DTC, the MIL will indicate them by blinking in the order from the lowest number to highest
number.
MIL CHECK
When the ignition switch is turned ON with the engine stop switch " ", the MIL will stay on for a few seconds, then go off. If the MIL
does not come on or stays on, inspect the MIL circuit (page 4-35).
CURRENT DTC/STORED DTC
The DTC is indicated in two ways according to the failure status.
• In case the ECM detects the problem at present, the MIL will start blinking as its DTC. It is possible to read out the MIL blink
pattern as the current DTC.
• In case the ECM does not detect any problem at present but has a problem stored in its memory, the MIL will not blink. If it is
necessary to retrieve the past problem, read out the stored DTC by following the DTC Readout procedure (page 4-6).
MCS INFORMATION
• The MCS can read out the DTC, stored data, current data and other ECM condition.
How to connect the MCS
Remove the seat (page 2-12).
Turn the ignition switch OFF.
Release the DLC [1] from the stay [2], then remove the dummy connector
from the DLC.
Connect the MCS to the DLC.
Turn the ignition switch ON with the engine stop switch " " and check the
DTC and stored data.
• Stored data indicates the engine conditions when the first malfunction
was detected.
DTC READOUT
Current DTC
Turn the ignition switch ON with the engine stop switch " " and check the MIL.
Start the engine and check the MIL. If the engine will not start, turn the starter motor for more than 10 seconds and check that the
MIL blinks.
If the MIL blinks, connect the MCS to the DLC (page 4-6).
Read the DTC, stored data and follow the DTC index (page 4-9).
• If the MIL does not blink, the system is normal at present. If you wish to read the stored DTC, connect the MCS to the DLC.
• If the MCS is not available, note how many times the MIL blinks and follow the DTC index (page 4-9). If you wish to read the
stored DTC, perform the following.
