PRECAUTIONS
On Board Diagnostic (OBD) System of Engine and A/T
INFOID:0000000001161417
The ECM has an on board diagnostic system. It will light up the malfunction indicator lamp (MI) to warn the
driver of a malfunction causing emission deterioration.
CAUTION:
Be sure to turn the ignition switch OFF and disconnect the negative battery cable before any repair
or inspection work. The open/short circuit of related switches, sensors, solenoid valves, etc. will
cause the MI to light up.
Be sure to connect and lock the connectors securely after work. A loose (unlocked) connector will
cause the MI to light up due to the open circuit. (Be sure the connector is free from water, grease,
dirt, bent terminals, etc.)
Certain systems and components, especially those related to OBD, may use a new style slide-lock-
ing type harness connector. For description and how to disconnect, refer to XX-XX, "*****"
.
Be sure to route and secure the harnesses properly after work. The interference of the harness with
a bracket, etc. may cause the MI to light up due to the short circuit.
Be sure to connect rubber tubes properly after work. A misconnected or disconnected rubber tube
may cause the MI to light up due to the malfunction of the fuel injection system, etc.
Be sure to erase the unnecessary malfunction information (repairs completed) from the ECM before
returning the vehicle to the customer.
General PrecautionsINFOID:0000000001161418
Always use a 12 volt battery as power source.
Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness con-
nector, turn ignition switch OFF and disconnect negative bat-
tery cable. Failure to do so may damage the ECM because
battery voltage is applied to ECM even if ignition switch is
turned OFF.
Before removing parts, turn ignition switch OFF and then dis-
connect battery ground cable.
Do not disassemble ECM.
If a battery cable is disconnected, the memory will return to
the ECM value.
The ECM will now start to self-control at its initial value.
Engine operation can vary slightly when the terminal is dis-
connected. However, this is not an indication of a malfunc-
tion. Do not replace parts because of a slight variation.
If the battery is disconnected, the following emission-related
diagnostic information will be lost within 24 hours.
-Diagnostic trouble codes
-1st trip diagnostic trouble codes
-Freeze frame data
-1st trip freeze frame data
-System readiness test (SRT) codes
-Test values
When connecting ECM harness connector (1), fasten (B) it
securely with a lever as far as it will go as shown in the figure.

FUEL PRESSURE RELEASE
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “FUEL PRESSURE RELEASE” in “WORK SUPPORT” mode with CONSULT-III.
3. Start engine.
4. After engine stalls, crank it two or three times to release all fuel pressure.
5. Turn ignition switch OFF.
With CONSULT-III
1. Remove fuel pump fuse located in IPDM E/R.
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
CAUTION:
Before disconnecting fuel line, release fuel pressure from fuel line to eliminate danger.
The fuel hose connection method used when taking fuel pressure check must not be used for other
purposes.
Be careful not to scratch or put debris around connection area when servicing, so that the quick
connector maintains sealability with O-rings inside.
Do not perform fuel pressure check with electrical systems operating (i.e. lights, rear defogger, A/C,
etc.) Fuel pressure gauge may indicate false readings due to varying engine load and changes in
manifold vacuum.
NOTE:
Prepare pans or saucers under the disconnected fuel line because the fuel may spill out. The fuel pres-
sure cannot be completely released because C11 models do not have fuel return system.
1. Release fuel pressure to zero.
2. Prepare fuel hose for fuel pressure check B and fuel tube
adapter (KV10118400) D, then connect fuel pressure gauge A.
: To quick connector
: To fuel tube (engine side)
C: Clamp
Use suitable fuel hose for fuel pressure check (genuine NIS-
SAN fuel hose without quick connector).
To avoid unnecessary force or tension to hose, use moder-
ately long fuel hose for fuel pressure check.
Do not use the fuel hose for checking fuel pressure with dam-
age or cracks on it.
Use Pressure Gauge to check fuel pressure.
3. Remove fuel hose.
Do not twist or kink fuel hose because it is plastic hose.
