TOYOTA CAMRY V20 1986 Service Information Current is led from the battery to terminal 12 of the running light relay.
Operation examples of the switch are shown below.
1. IGNITION SWITCH ºONº AND LIGHT CONTROL SWITCH ºOFFº
When the switch

Current is led from the battery to terminal 12 of the running light relay.
Operation examples of the switch are shown below.
1. IGNITION SWITCH ºONº AND LIGHT CONTROL SWITCH ºOFFº
When the switches are set, current is led from the battery to terminal 1 of the running light relay. Also,
because continuity is made between terminal 3 and the body ground, and 5 and the body ground of
the running light relay, the taillight control relay and headlight control relay are turned on.
Then the taillights and headlights light up.
HINT: Because terminal 14 of the running light relay is not grounded at all times, the headlight dimmer
relay is off, so that the headlights light up at the low beam.
2. LIGHT CONTROL SWITCH IN ºHEADº
When the switch is set, continuity is made between terminal 4 and the body ground, and 2 and the body
ground of the running light relay. Also, because the continuity is made between terminal 5 and the body
ground, and 3 and the body ground of the running light relay at all times, the taillights and headlights
light up.
HINT: When the headlight dimmer switch is set to ºHIGHº, continuity is made between terminal 13 of
the running light relay and the body ground. Also, because continuity is made between terminal 14 of
the running light relay and the body ground, the headlight dimmer relay is turned on. Then the head-
lights go on at the high beam.
3. HEADLIGHT DIMMER SWITCH IN ºFLASHº
When the switch is set, continuity is made between terminal 6 and the body ground, and 13 and the
body ground of the running light relay. Also, because the continuity is made between terminal 5 and
the body ground, and 14 and the body ground of the running light relay, the headlights flash.
4. ENGINE STOPS (IGNITION SWITCH ºONº)
When the engine is stopped, because the continuity between terminal 5 and terminal 10 of the running
light relay remains, so the running lights also remain.
HINT: If ignition switch is turned to ºOFFº, running lights will go off because the continuity between termi-
nal 5 and terminal 10 of the running light relay is cut off.
