Component Tests and General Diagnostics
INSPECTION1. Auto Antenna Models:
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 (The Antenna moves upward).
NOTE: 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 (The Antenna moves downward).
NOTE: These tests must be done quickly (within 3-5 seconds) to prevent the coil from burning out.
2. Auto Antenna Models:
INSPECT ANTENNA MOTOR CONTROL RELAY CIRCUIT
Disconnect the connector from the relay and inspect the connector on wire harness side, as shown in the chart below.
