The electrical system in your vehicle is designed to perform under reasonable
operating conditions without interference between components. Before any additional
electrical equipment is installed, it is recommended that you consult your dealer
or a reputable repair facility that is familiar with the vehicle and its systems.
If the vehicle is equipped with mobile radio equipment and/or mobile telephone,
it may have an effect upon the operation of the ECM. Radio Frequency Interference
(RFI) from the communications system can be picked up by the vehicle's wiring
harnesses and conducted into the ECM, giving it the wrong messages at the wrong
time. Although well shielded against RFI, the ECM should be further protected
by taking the following measures:
- Install the antenna as far as possible from the ECM. For instance, if the
ECM is located behind the center console area, then the antenna should be
mounted at the rear of the vehicle.
- Keep the antenna wiring a minimum of eight inches away from any wiring running
to the ECM and from the ECM itself. NEVER wind the antenna wire around any
other wiring.
- Mount the equipment as far from the ECM as possible. Be very careful during
installation not to drill through any wires or short a wire harness with a
mounting screw.
- Insure that the electrical feed wire(s) to the equipment are properly and
tightly connected. Loose connectors can cause interference.
- Make certain that the equipment is properly grounded to the vehicle. Poor
grounding can damage expensive equipment.
