• 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 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

ratio can be kept smaller.

- Be sure to ground the radio to vehicle body.
