Engine Control - Caution For Replacement Of ECM
April 17, 1998
PROCEDURE FOR REPLACEMENT OF ECM
'98 Camry, '98 Avalon
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 Immobilize" code to prevent permanent failure of the ECM.
In some instances the ECM is equipped the same in spite of the existence or nonexistence of the immobilizer system (see part numbers listed).
