System Description
FUNCTION
Multi-remote control system has the following function.
+Door lock (and set super lock)
+Door unlock (and release super lock)
+Hazard reminder
LOCK OPERATION
To lock door by multi-remote controller, the following two signals must be received.
+Key switch OFF (when ignition key is not in ignition key cylinder.)
+All 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
+through multi-remote control unit terminalj
10
+to super lock control unit terminalj2.
Then super lock control unit operates to lock doors and set super lock.
UNLOCK OPERATION
To unlock door by multi-remote controller, the following signal must be received.
+Key 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
+through multi-remote control unit terminalj
11
+to super lock control unit terminalj3.
Then super lock control unit operates to unlock doors and release super lock.
HAZARD REMINDER
When the doors are locked or unlocked by multi-remote controller, ground is supplied
+to terminalj
1of multi-remote control relay-1 and 2
+through multi-remote control unit terminalj
12.
Then the relays are energized and hazard warning lamp ¯ashes as follows
+Lock operation: Flash once
+Unlock 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.
+Driver side LOCKED signal (from driver side door unlock sensor)
+Door switch CLOSED signal
+Key switch signal (INSERTED/WITHDRAWN)
+Accessory power supply
+Signal from remote controller
For detailed procedure, refer to ``ID Code Entry Procedure'' in EL-239.

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:
+Main Harness
+Engine Room Harness (Engine Compartment)
To use the grid reference
1) Find the desired connector number on the connector list.
2) Find the grid reference.
3) On the drawing, ®nd 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
+Cavity: Less than 4
+Relay connector
+Cavity: From 5 to 8
+Cavity: More than 9
