Antenna System Diagnosis

CIRCUIT DESCRIPTION

The PKE receiver outputs 2.8 to 3.0 volts on CKT 219 to the antennas and returns on CKT 218. CKTs 218 and 219 are shielded leading to each antenna. PKE receiver terminal "B4" provides drain for the driver's door antenna shield while terminal "B3" is used for the rear antenna (coupe) or driver's door (convertible).

CHART TEST DESCRIPTION

Number(s) below refer to circled number(s) on the diagnostic chart.

1. Determines if a feed voltage of between 2.8 or 3.0 volts is present at the antenna.

2. Determines if there is an open in the antenna windings.

3. Determines the condition of the capacitor attached between antenna terminals "A" and "C".

4. Determines if there is any system response by bypassing the antenna system when bringing the transmitter within 1" inch (0.254 mm) of the receiver.
