Component Tests and General Diagnostics

Radio Antenna
If AM reception is extremely poor and FM reception "spits" or appears to have trouble holding stations, make sure that the antenna and antenna connectors are properly mated. If the antenna connectors are properly mated but the reception is still poor, replace the antenna cable.

NOTE: Many customers do not understand the limitations of FM reception. Refer the customer to the Owner Guide for information about the limitations of FM radio performance,

If only FM reception is poor, it is unlikely the antenna is at fault. Remove the radio chassis for service.

NOTE: If mast and cap are coated black they must be removed prior to test.

With antenna installed on vehicle and cable unplugged from radio, perform the following resistance tests using Rotunda 73 Digital Multimeter or equivalent at test points 1, 2 and 3 as shown. Probes must contact antenna at points specified by arrowheads.

If tests are satisfactory, the antenna is in good condition.

If any reading is unsatisfactory, replace the complete antenna and cable assembly.
