Troubleshooting Hints

1. Test the radio outside with the hood down.


Check radio reception in an area away from tall buildings, metal structures, power lines, fluorescent lighting and power tools.


2. Ignition noise on FM indicates a possible defective Electronic Ignition (EI) System. Refer to Ignition Noise" in the Performance Complaints section.


3. Check antenna coax connectors for corrosion or bad connections.


4. If a test antenna is used, ground the base of the antenna to the vehicle body.


5. Coated screws or bolts can act as poor grounds.


6. Before removing a speaker, check all accessible wiring and connectors to that speaker.

GENERAL

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove good in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked by monitoring for a voltage drop with the system operational (under load).


^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.


^ Refer to 'System Diagnosis.
