Wireless Equipment
When installing CB ham radio or a mobile phone, be sure to observe the following as it may adversely affect electronic control systems depending on its installation location.1. Keep the antenna as far as possible from the Engine Control Module.
2. Keep the antenna feeder line more than 20 cm (7.9 in) away from the harness of electronic controls. Do not let them run parallel for a long distance.
3. Adjust the antenna and feeder line so that the standing-wave ratio can be kept smaller.
4. Be sure to ground the radio to vehicle body.
