3. ERASURE OF TRANSPONDER KEY CODE
Do this operation to erase transponder key registration from the transponder key computer.
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.
*1: Insert the master cylinder into the key cylinder.
Turn the ignition switch to LOCK " ON 6 times within 15 seconds.
*2: Open and close driver's door 7 times and remove the master key within 20 seconds after completion of
the previous operation.
HINT:
When any operation time described above is over, registration mode completes.
When the next procedure is performed while the timer is working, the timer completes counting time,
then the next timer starts.
4. ECU COMMUNICATION ID REGISTRATION
NOTICE:
The ECU communication ID should be registered when the transponder key ECU and/or the
ECM is replaced, in order to match these ECM COMMUNICATION ID.
The engine cannot be started unless the ECM COMMUNICATION ID matches.
(a) Register the ECU communication ID.
(1) After the transponder key ECU and/or the ECM is replaced, turn the ignition switch ON (the en-
gine is not running).
(2) Short the Tc and CG terminals of the DLC3 and leave it as it is for 30 minutes.
(3) Check that the engine starts.

INSPECTION
1. INSPECTION TRANSPONDER KEY COIL CONTINU-
ITY
Check that there is continuity between terminals 1 and 2.
If continuity is not as specified, replace the coil.
2. INSPECT TRANSPONDER KEY ECU CIRCUIT
Connect the wire harness side connector to the ECU and in-
spect the wire harness side connector from the back side, as
shown in the table below.
ConditionTester connectionSpecified condition
Always6 ± 12Battery positive voltage
If the circuit is as specified, replace the ECU with a new one.
If the circuit is not as specified, inspect the circuit connected to
other parts.

Operation time:
Approx. 6 secs.
(b) Check for abnormal noise or binding during operation.
(c) With the sliding roof fully closed, check for water leakage.
(d) Check for a difference in level between the sliding roof

PRECAUTION
1. DO NOT HANDLE REFRIGERANT IN AN ENCLOSED
AREA OR NEAR AN OPEN FLAME
2. ALWAYS WEAR EYE PROTECTION
3. BE CAREFUL NOT TO GET LIQUID REFRIGERANT IN
YOUR EYES OR ON YOUR SKIN
If liquid refrigerant gets in your eyes or on your skin.
(a) Wash the area with lots of cool water.
CAUTION:
Do not rub your eyes or skin.
(b) Apply clean petroleum jelly to the skin.
(c) Go immediately to a physician or hospital for professional
treatment.
4. NEVER HEAT CONTAINER OR EXPOSE IT TO OPEN
FLAME
5. BE CAREFUL NOT TO DROP CONTAINER OR NOT TO
APPLY PHYSICAL SHOCKS TO IT
6. DO NOT OPERATE COMPRESSOR WITHOUT
ENOUGH REFRIGERANT IN REFRIGERATION SYS-
TEM
If there is not enough refrigerant in the refrigerant system, oil lu-
brication will be insufficient and compressor burnout may occur.
Necessary care should be taken to avoid this.
7. DO NOT OPEN PRESSURE MANIFOLD VALVE WHILE
COMPRESSOR IS OPERATING
If the high pressure valve is opened, refrigerant flows in the re-
verse direction and could cause the charging cylinder to rup-
ture, so open and close only the low pressure valve.
8. BE CAREFUL NOT TO OVERCHARGE SYSTEM WITH
REFRIGERANT
If refrigerant is overcharged, it causes problems such as insuffi-
cient cooling, poor fuel economy, engine overheating, etc.
