How to replace the Engine Control Module (ECM) on Toyota Avalon?

The process of Engine Control Module (ECM) replacement starts with disconnecting the negative battery terminal connector. Start by taking out the front door scuff plate RH followed by cowl side trim sub-assembly RH and instrument panel under cover sub-assembly No.2 and finally glove compartment door assembly. The replacement process of ECM begins by disconnecting five connectors while unfastening two nuts and removing bolt and ECM before separating ECM bracket and ECM bracket No.2 with two screws each. The installation requires mounting the ECM bracket No.2 to the ECM using two screws before attaching the ECM bracket with additional two screws and securing the ECM with two nuts and one bolt tightened to 5.5 N.m (56 kgf.cm, 49 in.lbf). Reconnect the 5 connectors to the ECM before reating the negative cable terminal of the battery. The last steps entail replacing the glove compartment door assembly together with instrument panel under cover sub-assembly No.2 alongside cowl side trim sub-assembly RH as well as front door scuff plate RH. Some vehicles need a memory reset and initialization because disconnecting the battery terminal demands these procedures.
