1986 TOYOTA CAMRY V20 key battery

3. INSPECT KEY INTERLOCK SOLENOID
(a) Disconnect the solenoid connector.
(b) Using an ohmmeter, measure the resistance between
terminals.
Standard resistance: 12.5 ± 16.5

(e) Apply the battery voltage between terminals.
Check that an operation noise can be heard
from the solenoid.
4. INSPECT SHIFT LOCK CONTROL SWITCH
Inspect that there is continuity between each terminals.

Seat Belt Warning
INSPECTION OF SEAT BELT WARNING
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the seat belt warning
relay and ground the terminal 5 on the wire harness
side.
(b) Turn the ignition switch ON, check that the warning
light lights.
If warning light does not light, test the bulb.
2. INSPECT BUCKLE SWITCH OPERATION
(a) Disconnect the connector from the switch.
(b) Check that there is no continuity between terminals
on the switch side connector with the belt fastened.
(c) Check that there is continuity between terminals on
the switch side connector with the belt unfastened.
If operation is not as specified, replace the seat belt inner.
3. INSPECT UNLOCK WARNING SWITCH OPERATION
(See page BE±1 3)
If operation is not as specified, replace the switch.
4. INSPECT SEAT BELT WARNING RELAY CIRCUIT
Disconnect the relay connector and inspect the connector
on the wire harness side as shown in the chart.

(Door Lock Signal)
HINT: When the relay circuit is as specified, inspect the
door lock signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter
to terminal 3 and the negative (±) lead to the ter-
minal 4.
(c) Set the door lock manual switch to UNLOCK,
check
that the voltage rises from 0 volts to battery volt-
age for approximately 0.2 seconds.
