2007 Toyota Sienna Parts Questions & Experts Answers

• Q: How to remove and install the Engine Control Module on 2007 Toyota Sienna?

  A: The first step for Engine Control Module (ECM) removal involves discharging the glove compartment door assembly through the right-side wall muscle followed by left-wall muscle to release stoppers before pulling the sub-assembly back. You must separate the 2 claws and 4 clips on the No. 2 instrument panel box for its successful removal. You should disconnect five ECM connectors before removing 2 nuts that allow you to extract the ECM. When dealing with vehicles that have 10 speakers systems, technicians must disconnect both the 5 ECM connectors and 2 stereo components amplifier connectors before removing the 4 nuts to extract the ECM with stereo components amplifier. Use the supplied 2 nuts to attach the ECM before tightening them to 5.5 Nm (56 kgf.cm, 49 in. lbs.) and then connect its 5 ECM connectors. For vehicles with a 10 speakers system the ECM installation requires 4 nuts to be torqued to 5.5 Nm (56 kgf.cm, 49 in. lbs.) then connection of 5 ECM connectors and 2 stereo components amplifier connectors. Begin by installing the instrument panel box number two before moving on to install the glove compartment door assembly by shoving it forward and attaching the right wall before the left wall to seat the stoppers. The process of replacing the ECM requires a step of performing distance control ECU recognition in ECM.
