FUEL SYSTEM (PGM-FI)
Connect the battery harness adaptor to the DLClfuel pump sub harness 4P
(Red) connector as shown.
TOOL:
Battery harness adaptor 070MZ·KRN0100 or
070MZ·KRNA 100
(U.S.A . only)
Connect the battery harness to the battery harness adaptor as shown.
TOOL:
Battery harness 070MZ· MEN0100 or
070MZ·MENA100
(U.S.A . only)
Connect the battery harness positive (+) cable and battery harness negative
H
cable to the 12
V
battery.
NOTE :
Before connecting the battery harness cables to the 12 V battery , make
sure the battery harness selector switches are OFF .
Select the power delivery by operating the selector switches as follows:
- "ECM" selector switch ON : Power to ECM only
- "PUMP" selector switch ON: Power to fuel pump only
- Both selector switches ON: Power to ECM and fuel pump
Mil Bli nk Pattern
If the MCS is nol available, DTG 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 OTe
(the sub code cannot
be
displayed by the MIL).
The MIL will blink the current
DIG,
in case the ECM detects the problem
at present, when running the engine or connecting the 12 V battery to
the fuel pump sub harness (-ECM" selector switch is ON ) (page 6· 19).
The MIL will slay ON when the engine speed is ovef 4,000 rpm.
The MIL has two types of blinks, a long blink and short blink. The long
blinking lasts for 1.2 seconds, the short blinking lasts for 0.4 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 OTC. the MIL will indicate them by
blinking in the order from the lowest number to highest number.

MIL
When starting the engine, the MIL will stay on for 2 seconds, then go off. If the MIL does not come on , inspect the MIL circui t (page
6-38).
CURRENT oTC/FREEZE oTC
The OTC is indicated in
two
ways according to the failure status.
In the case that the ECM detects a problem at present, the MIL will come on and will start to blink the OTC when running the
engine or connecting the 12 V battery to the fuel pump sub harness ("ECM" selector switch is ON) (page 6· 19).
In the case that the ECM does not detect any problem al present but has a problem stored in its memory, the MIL will not fight
and blink. To retrieve the past problem code, readout the freeze OTC by following the OTC readout procedure.
