PROCEDURE FOR REPLACEMENT OF ECM
Model(s): 1998 Toyota Camry, Avalon
Section: Electrical
Bulletin No.: EL003-98
Date: April 17, 1998
INTRODUCTION
On some non-immobilizer equipped 1998 Camry and Avalon models, the ECM used is the same as for immobilizer equipped vehicles. For these models, it is necessary to register a "without engine immobilizer" code to prevent permanent failure of the ECM.
NOTE:
In some instances the ECM is equipped the same in spite of the existence or nonexistence of the immobilizer system (see part numbers listed below).
