On certain vehicles equipped with a 1ZZ-FE engine and a two-wheel drive transmission, the Engine Control Module (ECM) may have been improperly manufactured. There is a possibility that a crack may develop at certain solder points or on varistors on the circuit board. In most cases, if a crack occurs at certain points or on certain varistors, the engine warning lamp could be illuminated, harsh shifting could result, or the engine may not start. In limited instances, if cracking occurs on particular solder points or varistors, the engine could stop while the vehicle is being driven, increasing the risk of a crash causing personal injury. Correction: Dealers will inspect and, if necessary, replace the ECM.
