2.
Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT”
mode with CONSULT-II.
3.
Start engine.
4.
After engine stalls, crank it two or three times to release all fuel
pressure.
5.
Turn ignition switch “OFF”.
Without CONSULT-II
1.
Remove fuel pump fuse located in fuse box.
2.
Start engine.
3.
After engine stalls, crank it two or three times to release all fuel
pressure.
4.
Turn ignition switch “OFF”.
5.
Reinstall fuel pump fuse after servicing fuel system.
FUEL PRESSURE CHECK
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
NOTE:
●
Use Fuel Pressure Gauge Kit (J-44321) to check fuel pressure.
●
Prepare pans or saucers under the disconnected fuel line because the fuel mag spill out. The fuel
pressure cannot be completely released because F50 models do not have fuel return system.
1.
Release fuel pressure to zero. Refer to
EC-48, "FUEL PRESSURE RELEASE"
2.
Install the inline fuel quick disconnected fitting between fuel
damper and injector tube.
3.
Connect the fuel pressure test gauge (quick connector adapter
hose) to the inline fuel quick disconnected fitting.
4.
Turn ignition switch “ON” and check for fuel leakage.
5.
Start engine and check for fuel leakage.
6.
Read the indication of fuel pressure gauge.
7.
If result is unsatisfactory, go to next step.
8.
Check the following.
●
Fuel hoses and fuel tubes for clogging
●
Fuel filter for clogging
●

ON BOARD DIAGNOSTIC (OBD) SYSTEM

Introduction
EBS00LVO
The ECM has an on board diagnostic system, which detects malfunctions related to engine sensors or actua-
tors. The ECM also records various emission-related diagnostic information including:
The above information can be checked using procedures listed in the table below.
×
: Applicable
—: Not applicable
*1: 1st trip DTCs for self-diagnoses concerning SRT items cannot be shown on the GST display.
*2: When DTC and 1st trip DTC simultaneously appear on the display, they cannot be clearly distinguished from each other.
The malfunction indicator lamp (MIL) on the instrument panel lights up when the same malfunction is detected
in two consecutive trips (Two trip detection logic), or when the ECM enters fail-safe mode. (Refer to
Two Trip Detection Logic
EBS00LVP
When a malfunction is detected for the first time, 1st trip DTC and 1st trip Freeze Frame data are stored in the
ECM memory. The MIL will not light up at this stage. <1st trip>
If the same malfunction is detected again during the next drive, the DTC and Freeze Frame data are stored in
the ECM memory, and the MIL lights up. The MIL lights up at the same time when the DTC is stored. <2nd
trip> The “trip” in the “Two Trip Detection Logic” means a driving mode in which self-diagnosis is performed
during vehicle operation. Specific on board diagnostic items will cause the ECM to light up or blink the MIL,
and store DTC and Freeze Frame data, even in the 1st trip, as shown below.
