(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock control switch to LOCK, check that the
voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.

INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the key−off power
window signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 5 and the negative (−) lead to terminal 11.
(c) Close the door with ignition switch turned to LOCK or
ACC, check that the meter needle indicates battery posi-
tive voltage.
(d) Open the door, check that the meter needle indicates 0 V.
(e) Turn the ignition switch ON, check that the meter needle
indicate battery positive voltage again.
If operation is not as specified, replace the relay.

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.

CUIT
Disconnect the connector from the relay and inspect the con-
nector on wire harness side, as shown in the chart below.
