Nissan Qashqai J11. Manual — part 178
ECH-10
< PRECAUTION >
[HRA2DDT]
PRECAUTIONS
• 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.
• Do not disassemble fuel pump.
If NG, take proper action.
• Do not disassemble fuel injector.
If NG, replace fuel injector.
• Do not depress accelerator pedal when staring.
• Immediately after staring, do not rev up engine unnecessarily.
• 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 standingwave
radio can be kept smaller.
- Be sure to ground the radio to vehicle body.
