FUEL SYSTEM (PGM-FI)
MIL Blink Pattern
• If the HDS pocket tester is not available, DTC can be read from the
ECM memory by the MIL blink pattern.
• The number of MIL blinks is the equivalent 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 ON or idling with the
sidestand down. The MIL will stay ON when the engine speed is
-1
over 5,000 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 0.5
seconds. One long blink is the equivalent of ten short blinks. For
example, when two long blinks are followed by five short blinks, the
MIL is 25 (two long blinks = 20 blinks, plus five 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 and engine stop switch " ", the MIL will stay on for a few seconds, then go off. If the
MIL does not come on, inspect the MIL circuit (page 5-53).
CURRENT DTC/FREEZE 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 come on and the MIL will start to blink as its DTC when the
sidestand is lowered. It is possible to readout 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 light
and blink. If it is necessary to retrieve the past problem, readout the freeze DTC by following the DTC readout proce-
dure.
HDS POCKET TESTER INFORMATION
• The HDS pocket tester can readout the DTC, freeze data, current data and other ECM condition.
How to connect the HDS Pocket Tester
Turn the ignition switch OFF.
Remove the left side cover (page 2-4).
Remove the dummy connector from the DLC.
Connect the HDS pocket tester to the DLC.
Turn the ignition switch ON and engine stop switch " ", check the DTC
and freeze data.
• Freeze data indicates the engine conditions when the first malfunc-
tion was detected.
ECM reset
The HDS pocket tester can reset the ECM data including the DTC,
freeze data and some learning memory.
DTC READOUT
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.
• When the ignition switch is turned ON, the MIL will stay on for a few
seconds, then go off.
If the MIL stays on or blinks, connect the HDS Pocket Tester to the DLC
(page 5-14).
Read the DTC, freeze data and follow the troubleshooting index (page
5-17).
To read the DTC with the MIL blinking, refer to the following proce-
dure.
