CAUTION:
If Engine Control Module (ECM) replacement is instructed in following test, always ensure ECM electrical connectors and ground circuits are okay. If either are defective, repair and repeat testing to confirm ECM malfunction. On models equipped with engine immobilizer, if ECM is replaced, ECM must be programmed with proper ignition key code for engine immobilizer system. For programming procedures, see COMPUTER RELEARN PROCEDURES - TOYOTA
article in GENERAL INFORMATION, or appropriate ENGINE IMMOBILIZER SYSTEMS article in ACCESSORIES & EQUIPMENT.
NOTE:
If DTCs related to IAT sensor, HO2S, TP control motor and sensor, ECT sensor and VP sensor are output simultaneously, the E2 sensor ground circuit at terminal No. 28 (Brown/White wire) at ECM connector E5 may be open. See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL. For ECM electrical connector terminal identification, see Figure. It may be necessary to check Brown/White wire between splice E10 and terminal No. 28 at ECM connector E5. See Figure.
