How to remove and replace the Engine Control Module (ECM) on 2007 Toyota Tundra?

You should disconnect the negative battery cable before starting Engine Control Module (ECM) replacement operations but wait for at least 90 seconds after turning off the ignition switch to allow the navigation system to record memory and settings. Before accessing the ECM you must first remove the 3 connector holder block bolts and move it to an unobstructed position. While utilizing the levers simultaneously push the locks so that the lock lever elevates to a 90-degree angle before disconnecting the two connectors to prevent damages. Begin by removing the 4 ECM attaching bolts followed by carefully removing the sponge gasket layer while treating the remaining tape with gasket remover or equivalent products and then covering the ECM connector with cloth. The use of a cutter knife to extract tape should be done carefully while maintaining the integrity of the ECM seal's surface. When ready to install, clean the ECM surface using non-residue solvent then apply a new gasket onto the ECM. Resecure the ECM with the 4 bolts to complete installation. Verify proper torque at 8.0 N.m (82 kgf.cm, 71 in.lbf) and check that the gasket remains unfolded and free of any folds. Secure the ECM connectors with careful motion that pushes each lock lever down but confirms the lock lever reaches 90 degrees before contact to stay safe from damage. The wire harness must not be twisted throughout setup operations. The connector holder block deserves reinstallation after tightening its bolts to 7.3 N.m (74 kgf.cm, 65 in.lbf). Once this step is complete, you can connect the negative battery cable. Some systems need post-reconnection initialization procedures.
