System Description
CIRCUIT OPERATION
[Example]
Aiming switch ``0''
lWhen the aiming switch is set to ``0'', the motor will not start.
This is because the power terminals are positioned at the
nonconductive section of the sensor's rotary unit.
Aiming switch ``0''®``1''
lWhen the aiming switch is moved from ``0'' to ``1'', the sen-
sor's conductive section activates the relay. Power is sup-
plied through the relay to the motor. The headlamps will then
move in the ``DOWN'' direction.
lThe motor continues to rotate while the rotary unit of the
sensor moves from point A to point B.
lThe power terminals will then be positioned at the noncon-
ductive section, disconnecting the power to the motor. The
motor will then stop.
Aiming switch ``1''®``0''
lWhen the aiming switch is moved from ``1'' to ``0'', the sen-
sor's conductive section activates the relay. Power is sup-
plied through the relay to the motor. The motor will rotate to
move the headlamps in the ``UP'' direction.
lWhen the rotary unit of the sensor moves from point B to
point A, the motor will stop.

System Description
FUNCTION
Multi-remote control system has the following function.
lDoor lock
lDoor unlock
lHazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder.)
lAll door switches CLOSED
When the LOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
lthrough multi-remote control unit terminalV10
lto door lock timer terminalV5and
lto multi-remote control relay-3 (LOCK) terminalV1.
Then door lock timer operates to lock doors (except for driver's door) and mutli-remote control relay-3
(LOCK) energized to lock driver's door.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
lKey switch OFF (when ignition key is not in ignition key cylinder)
When the UNLOCK signal is input to multi-remote control unit (the antenna of the system is combined with
multi-remote control unit), ground is supplied
lthrough multi-remote control unit terminalV11
lto door lock timer terminalV8and
lto multi-remote control relay-4 (UNLOCK) terminalV1.
Then door lock timer operates to unlock doors (except for driver's door) and mutli-remote control relay-4
(UNLOCK) is energized to unlock driver's door.
HAZARD REMINDER
When the doors and locked or unlocked by multi-remote controller, ground is supplied
lto terminalV1of multi-remote control relay-1 and 2
lthrough multi-remote control unit terminalV12.
Then the relays are energized and hazard warning lamp flashes as follows
lLock operation: Flash once
lUnlock operation: Flash twice
MULTI-REMOTE CONTROLLER ID CODE ENTRY
A maximum of four remote controllers can be entered. Any attempt to enter a remote controller will erase
all ID codes previously entered. Therefore, be sure to receive all remote controllers from the vehicle owner
when any ID code entry is performed.
To enter ID code entry, the following signals must be input to the multi-remote control unit.
lDriver side LOCKED signal (from driver side door unlock sensor)
lDoor switch CLOSED signal
lKey switch signal (INSERTED/WITHDRAWN)
lAccessory power supply
lSignal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-182.

How to Read Harness Layout
Example:
G2E1B/6: ASCD ACTUATOR
Connector color / Cavity
Connector number
Grid reference
The following Harness Layouts use a map style grid to help locate connectors on the drawings:
lMain Harness (Instrument Panel, Engine Compartment)
lEngine Room Harness
lEngine Control Harness
To use the grid reference
1) Find the desired connector number on the connector list.
2) Find the grid reference.
3) On the drawing, find the crossing of the grid reference letter column and number row.
4) Find the connector number in the crossing zone.
5) Follow the line (if used) to the connector.
CONNECTOR SYMBOL
Main symbols of connector (in Harness Layout) are indicated in the below.
Connector typeWater proof type Standard type
Male Female Male Female
lCavity: Less than 4
lRelay connector
lCavity: From 5 to 8
lCavity: More than 9
