SC400 You will find this ECM under floor on the passenger side. Lift the carpet back on the passenger side you will see a large plastic hump secured by two 10 mm nuts. Remove the 10 mm nuts and another 10 mm bolt on the other side. Note it is a tight fit and take notice of a bracket that is attaché to the ECM its orientation is unique so be careful how it slides out of the plastic cavity because if you do not place it back into the same position when you re-install the ECM the plastic cover will not secure tightly and possible moisture from snow or rain could enter into the cavity allowing a possible damage to the ECM.
