The SVX ECM has a built-in logic which controls the vehicle acceleration from a standing start. The logic controls the power during light to medium acceleration. THIS CONDITION IS "NORMAL", and no repair attempts should be made to change it. This condition is sometimes mis-diagnosed as a hesitation.
If a customer complains of a hesitation and it is not the normal condition as described above, make sure the customer is using premium fuel. A check of all basic engine functions should be performed to make sure they are all normal. If all engine functions are found to be normal, follow the procedures below.
CAUTION: BEFORE WORKING ON THE ECM, REMOVE THE STATIC CHARGE FROM YOUR BODY BY MOMENTARILY TOUCHING AN EARTH GROUND, SUCH AS: A COLD WATER PIPE, METAL BUILDING SUPPORT BEAM OR A CLEAN, METAL AREA OF THE VEHICLE.
A modified ECM will be incorporated in production beginning with 94MY vehicles. Modified ECMs can be identified by a black dot next to the parts number label.
