How to remove and install the Engine Control Module on 2007 Toyota Corolla?

Question

Accepted Answer

The Engine Control Module (Ecm) requires a battery negative terminal disconnection as the initial procedure for its removal. The glove compartment door assembly will be removed after unscrewing [A] from door stoppers and bending the upper assembly parts to free the stoppers [B] before lifting the assembly upward. You need a clip remover tool to remove the Ecm by executing the following steps: firstly disconnect the 2 clips with the tool before opening the cover and disconnecting the 4 Ecm connectors [B] and pulling the wire harness from the wire harness clamp [C] and eliminating the 2 screws [D] until you can extract the Ecm with the claw and clip. You must separate the Ecm cover from the Ecm at this time. Remove the 4 screws for Ecm bracket No. 1 when working with Delco made products whereas Denso made products require removal of 2 screws for each Ecm bracket No. 1, No. 2 and No. 3 successively. The first step for installation should be to secure Ecm Bracket No. 3 for Denso with two screws at a torque of 3.2 N.m (33 kgf.cm, 28 in.lbf), then move to Ecm Bracket No. 2 secured with two screws at the same torque before moving forward with Ecm Bracket No. 1 for Denso using two screws at 3.2 N.m (33 kgf.cm, 28 in.lbf), and finally securing Ecm Bracket No. 1 for Delco with four screws at the same torque. Secure the new Ecm cover onto the Ecm by tightening 2 screws to 3.0 N.m (31 kgf.cm, 27 in.lbf) torque before reattaching the 4 Ecm connectors and installing the clamp [C] followed by 2 clip closure. The glove compartment door assembly needs to be fitted before conducting a battery terminal tightness check to 5.4 N.m (55 kgf.cm, 48 in.lbf) followed by VIN registration.
