2. REPLACE DOOR CONTROL RECEIVER AND TRANS-
MITTER
NOTICE:
When replacing the door control receiver and transmitter,
registration of recognition code is necessary because they
are provided as single components.
(a) Select which operation mode should be performed from
the following modes.
Add mode
Rewrite mode
Prohibition mode
Confirmation mode
HINT:
The add mode is used to retain codes already registered
while you register new recognition codes. This mode is
used when adding a transmitter. However, if the number
of registered codes exceeds 4 codes, previously regis-
tered codes are correspondingly erased in order, starting
from the first registered code.
The rewrite mode is used to erase all previously regis-
tered codes and register only new recognition codes.
The prohibition mode is used to erase all registered codes
and cancels the wireless door lock function. Use this
mode when the transmitter is lost.
The confirmation mode is for confirming how many recog-
nition codes are already registered before you register
additional recognition codes.
(b) Follow the chart on the following pages to register the
transmitter recognition code at the wireless door lock con-
trol receiver.
HINT:
When procedure is out of the specified, the operation re-
turns to normal operation.
Maximum 4 recognition codes can be registered.

9. ERASURE OF TRANSPONDER KEY CODE
(a) Do this operation to erase transponder key registration from the transponder key ECU.
HINT:
Delete all other master and sub±key codes leaving the master key code to use the operation. When using
the key which was used before deletion, it is necessary to register the code again.
(b) Initial condition: All doors closed, not key in cylinder.

PRE±CHECK
1. TRANSPONDER KEY ECU INPUT CONDITION DIS-
PLAY READ CODE
(a) Connect the positive (+) lead from the volt meter (Analog
Type) to OP1 of the check connector and the negative (±)
lead to E1 of the check connector.
(b) Insert the ignition key in the key cylinder.
(c) Read the code from the movement of the tester needle.
If no code is output, turn the ignition switch ON.
If a code is now output, check if the DOME fuse is blown.
HINT:

The code can be read using a luminous diode (Recom-
mend activation current 10 ± 20 mA) instead of a tester.

A digital tester can also be used.
Display condition:

When there are multiple codes, they are output in order
staring from the lowest code.

After all the codes are output, Lo is displayed for 4.5
secs., then all the code are output again starting from the
lowest code.

If the situation changes during code output, Lo is output
for 4.5 secs. after output of the current code ceases, then
the codes are output again starting from the lowest code.
E.g. while 11 (out of 11 and 21) is being output, conditions
change and 12 is added. So after 11 is output, Lo is output
for 4.5 secs., then 11, 12 and 21 are output.
