IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
EG0G4–02
The ECM has been designed so that it will not be affected by
outside interference.
However, if your vehicle is equipped with a CB radio trans-
ceiver, etc. (even one with about 10 W output), it may, at
times, have an affect upon ECM operation, especially if the
antenna and feeder are installed nearby.
Therefore, observe the following precautions:
1. Install the antenna as far away as possible from the ECM.
The ECM is located under the dash board on the passenger’s
side so the antenna should be installed at the rear side of the
vehicle.
2. Keep the antenna feeder as far away as possible from the
ECM wires–at least 20 cm (7.87 in.)–and, especially, do not
wind them together.
3. Check that the feeder and antenna are properly adjusted.
4. Do not equip your vehicle with a powerful mobile radio
system.
5. Do not open the cover or the case of the ECM unless
absolutely necessary. (If the IC terminals are touched, the IC
may be destroyed by static electricity.)
AIR INDUCTION SYSTEM
EG0G5–01
1. Separation of the engine oil dipstick, oil filler cap, PCV hose,
etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out of
tune.
