Nissan Titan A60. Instruction — part 336

EC-10

< PRECAUTION >

[VK56DE]

PRECAUTIONS

• After performing each TROUBLE DIAGNOSIS, perform DTC

Confirmation Procedure or Overall Function Check.

The DTC should not be displayed in the DTC Confirmation

Procedure if the repair is completed. The Overall Function

Check should be a good result if the repair is completed.

• When measuring ECM signals with a circuit tester, never allow

the two tester probes to contact.

Accidental contact of probes will cause a short circuit and

damage the ECM power transistor.

• Do not use ECM ground terminals when measuring input/out-

put voltage. Doing so may result in damage to the ECM's tran-

sistor. Use a ground other than ECM terminals, such as the

ground.

• B1 indicates the bank 1, B2 indicates the bank 2 as shown in

the figure.

• Do not operate fuel pump when there is no fuel in lines.

• Tighten fuel hose clamps to the specified torque.

• Do not depress accelerator pedal when starting.

• Immediately after starting, do not rev up engine unnecessar-

ily.

• Do not rev up engine just prior to shutdown.

• 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

radio can be kept smaller.

- Be sure to ground the radio to vehicle body.

• <Flexible Fuel Vehicle>

When replacing the ECM, there is a small possibility that engine does not start under cold weather.

This is caused by the large difference between the actual and the presumed ethanol mixture ratio. In

such a case, perform

EC-119, "Ethanol Mixture Ratio Adaptation (Flexible Fuel Vehicle)"

.
