If circuit is as specified, inspect the door lock signal.
If the circuit is not as specified, inspect the circuits connected
to other parts.
11. INSPECT DOOR LOCK SIGNAL
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 3 and the negative ( −) lead to terminal 4.
(c) Set the door lock manual switch to UNLOCK, and check
that the voltage rises from 0 V to battery positive voltage
for approximately 0.2 seconds.
(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock manual switch to LOCK, and 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.
