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. The MIL will stay ON when
the engine speed is over 2,000 min
• The MIL has two types of blinks, a long blink and
short blink. The long blinking lasts for 1.3 sec-
onds, 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 "
onds, then go off. If the MIL does not come on, inspect the MIL circuit (page 6-43).
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. 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 procedure (page 6-12).
