1986 TOYOTA CAMRY V20 fuse

NOTICE:
1. Turn off all electrical components and the ignition
switch before replacing a fuse or fusible link. Do not
exceed the fuse or fusible link amperage rating.
2. Always use a fuse puller for removing and inserting
a fuse. Remove and insert straight in and out without
twisting. Twisting could force open the terminals too
much, resulting in a bad connection.
If a fuse or fusible link continues to blow, a short circuit is
indicated. The system must be checked by a qualified tech-
nician.

CHECK FOR SHORT CIRCUIT
(a) Remove the blown fuse and eliminate all toads from
the fuse.
(b) Connect a test bulb in place of the fuse.
(e) Establish conditions in which the test bulb comes on.
Example:
(A) ± Ignition SW on
(B) ± Ignition SW and SW 1 on
(C) ± Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 oft (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while
watching the test bulb.
The short lies between the connector where the test
bulb stays lit and the connector where the bulb goes
out.
(e) Find the exact location of the short by lightly shaking
the problem wire along the body. (c) Use a volt/ohmmeter with high impedance (10 k

/V
minimum) for troubleshooting of the electrical circuit.

Taillight Failure Sensor
INSPECTION OF SENSOR
1. INSPECT WARNING LIGHT OPERATION
(a) Disconnect the connector from the failure sensor and
ground the terminal 3 on the wire harness side.
(b) Remove the CHARGE fuse and turn the ignition
switch ON, check that the bulb lights.
If bulb does not light, inspect the bulb.
2. INSPECT SENSOR CIRCUIT
Disconnect the failure sensor connector and inspect the
connector on the wire harness side as shown in the chart.
If circuit is as specified, replace the relay.
