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

The installation process for 2GR-FE engine control system ECM starts by attaching 4 ECM brackets with 3.0 Nm (31 kgf-cm, 27 in-lbf) torques then using 3 nuts to fix the ECM to the body also with 8.0 Nm (82 kgf-cm, 71 in-lbf). Install the 2 ECM connectors while checking for any contamination between the connectors and other parts before securing the 2 levers. Install the ECM body using three nuts which should be torqued to 8.0 Nm (82 kgf-cm, 71 in-lbf). Install the cowl top panel outer then mount the windshield wiper motor and links followed by the cowl top ventilator louver sub-assembly and both right and left windshield wiper arm assemblies and blades. The cable must be connected to the negative battery terminal after completing these actions while some systems demand initialization during reconnection. The Service Bulletin requires the ECM communication ID registration for the immobiliser system when replacing the ECM. The initialization process begins with turning on the ignition switch (IG) and activating the cruise control main switch while depressing the brake pedal followed by pressing the cruise control main switch to RES/ACC three times within three seconds which produces buzzer sounds. The dimmer switch must not be enabled while conducting operations because incorrect optical axis configuration could occur so readjust the axis if the switch was accidentally turned on.

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.
