Mobile Radio Equipment Precautions

VEHICLES EQUIPPED WITH MOBILE RADIO SYSTEM (HAM, CB, ETC.)
The Electronic Control Unit (ECU) has been designed so that it will not be affect by outside interference. However, if your vehicle is equipped with a CB radio transceiver, etc. (even one with about 10 W output), it may, at times, have an affect upon ECU operation, especially if the antenna and feeder are installed nearby.

Therefore, observe the following precautions:






1. Install the antenna as far as possible from the ECU. The ECU is located under under the radio 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 ECU 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.
