Transaxle Range Switch: Diagnostic Aids
Aftermarket Accessories
Always check for aftermarket accessories as the first step in diagnosing electrical problems. If the vehicle is so equipped, disconnect the system to verify
that these add-on accessories are not the cause of the problems.
Some possible causes of vehicle problems related to aftermarket accessories include:
1. Power feeds connected to points other than the Battery.
2. Antenna location.
3. Transceiver wiring located too close to vehicle electronic modules or wiring.
4. Poor shielding or poor connectors on antenna feed line.
