Hi I'm Wayne

I will help you with this

my first question is did you replace the V-ecu, (the one behind the seat?). If so then what type of I-ecu do you have? Does it have a digital readout with 4 buttons on the bottom

common issues with these are I-ecu circuit board corroding inside the unit, the wires on the auto manual switch become loose or break off, the harness shorts out under the fuse panel as the seat rides up and down, the bolts were to long and chewed through the harness, the V-ecu computer chip will become loose causing weird issues, and relays in the relay box failing causing engine issues. When you see the code 187 no signal it means the v ecu isn't receiving power or a ground

I hope this helped you
