ECM
89661-02M31
Q: How to install the Engine Control Module on Toyota Corolla?
A:
The first step for 2ZR-FE engine control ECM installation requires attaching the 2 ECM brackets to the ECM unit using 4 screws tightened to 8.8 Nm (90 kgf-cm, 78 in-lbf). The installation requires securement of the ECM using 3 bolts tightened to 8.0 Nm (82 kgf-cm, 71 in-lbf). This step must include connecting both ECM connectors while maintaining a shield from dirt or water contamination. Lastly, lock the 2 levers securely. The installation process continues by adding the wire harness clamp to its place. The procedure requires installation of the air cleaner case sub-assembly followed by the air cleaner cap sub-assembly. Afterward connect a cable between the negative terminal of the battery. For initialization procedures avoid outright battery removal because a new start-up requires conducting the Reset Memory (AT initialization) upon ECM replacement and performing the Registration (VIN registration) according to protocol.
