INSPECTION
1. GLASS PRINTED ANTENNA INSPECTION PROCE-
DURE
NOTICE:

When cleaning the glass, use soft dry cloth, and wipe
the glass in the direction of the wire.
Take care not to damage the wires.

Do not use detergents or glass cleaners with abrasive
ingredients.
NOTICE:
In order not to damage the glass printed antenna, wrap up
the tip of the tester stick with aluminum foil as shown in the
illustration and check by holding the aluminum foil with a
finger.
By placing and moving the tester stick along the glass printed
antenna, check if continuity exists.
HINT:
Matching module is built in the bus bar of the glass printed an-
tenna (main terminal side) of CAMRY and no continuity exists
between the terminal and the antenna. Therefore, for the conti-
nuity checking of the glass printed antenna on the main anten-
na side of CAMRY, place one probe of the tester on the position
beside the bus bar (position shown in the illustration) and check
by making the other probe of the tester move along.
2. GLASS PRINTED ANTENNA REPAIR PROCEDURE
(a) Clean the broken wire tips with grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire for
repair.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).

REGISTRATION PROCEDURE
1. KEY REGISTRATION IN AUTOMATIC REGISTRATION MODE
(a) Registration of a new transponder key.
HINT:

This must be done when you have installed a new ECM.

The new ECM is in the automatic key code registration mode. The already fixed number of key codes
for this ECM can be registered.
On this type of vehicle, up to 4 key codes can be registered.

In the automatic registration mode, the last key registered becomes sub±key.
