• When installing C.B. ham radio or a mobile phone, be sure to

observe the following as it may adversely affect electronic
control systems depending on installation location.

- Keep the antenna as far as possible from the electronic con-

trol units.

- Keep the antenna feeder line more than 20 cm (8 in) away

from the harness of electronic controls.
Do not let them run parallel for a long distance.

- Adjust the antenna and feeder line so that the standing-wave

ratio can be kept smaller.

- Be sure to ground the radio to vehicle body.

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 J10 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.
