ANTENNA
INSPECTION
1. INSPECT ANTENNA MOTOR
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (−) lead to terminal 2.
(b) Check that the motor turns (moves upward).
NOTICE:
These tests must be done quickly (within 3 − 5 seconds) to
prevent the coil from burning out.
(c) Then, reverse the polarity, check that the motor turns the
opposite way (moves downward).
NOTICE:
These tests must be done quickly (within 3 − 5 seconds) to
prevent the coil from burning out.
2. INSPECT ANTENNA MOTOR CONTROL RELAY CIR-
CUIT
Disconnect the connector from the relay and inspect the con-
nector on wire harness side, as shown in the chart below.

REPLACEMENT
1. REMOVE ANTENNA ROD
HINT:
Perform this operation with negative (−) cable connected to the
battery terminal.
(a) Turn the ignition switch to ”LOCK” position.
(b) Remove the antenna nut.
(c) Press the ”AM” buttons on the radio receiver, and simulta-
neously turn the ignition switch to ”ACC” position.
HINT:
The rod will extend fully and be released from the motor
antenna.
After removing the antenna rod, leave the ignition switch
as ”ACC”.
NOTICE:
To prevent body damage when the antenna rod is released,
hold the rod while it comes out.
2. INSTALL ANTENNA ROD
(a) Insert the cable of the rod until it reaches the bottom.
HINT:
When inserting the cable, the teeth on the cable must face to-
ward the front of the vehicle.
(b) Wind the cable to retract the rod by turning the ignition
switch to ”LOCK” position.
HINT:
If the ignition switch is already in ”LOCK” position, perform
step 1 (c) first, then turn the ignition switch to ”ACC” posi-
tion.
In case the cable is not wound, twist it as shown in the il-
lustration.
Even if the rod has not retracted fully, install the antenna
nut and inspect the antenna rod operation. It will finally re-
tract fully.
(c) Inspect the antenna rod operation by pushing the radio
wave band select buttons.
