• 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.

PRECAUTIONS

• 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.
