been a minute. so Ive put about 7500 km on my N12 to N16 swapped '07. the entire time the trifecta has been illuminated. as well the airbag / seatbelt light in the speedo. on that one, I did have the seats out when doing a deep clean. apparently you have to reset the codes after the seat electrical plug has been apart. looking for confirmation on this.

the trifecta lights. the scanner at my brothers work said it was a connection at the abs solenoid. I don't remember the code. I did have the front end including suspension removed for the motor swap. is there something I could have unplugged and replugged there that would have to be reset by the proper tool as well? Ive read some threads that said if your alignment is off it will set off the trifecta as well (yaw sensor). looking for some genuine help.

hope your all safe in these weird times

 

If the steering rack position sensor and steering wheel position sensor are not aligned, you will get those errors. I recently had my front end disassembled, and my steering wheel had spun around once before reassembly. I had to disconnect the steering u-join, spin the steering wheel around, and reconnect for the lights to go away. Alternately, the factory service guide say you need to reprogram the sensors for zero position alignment. It was easier for me to disconnect the steering joint and reposition.

 

+1 Check the connections and that steering rack sensor. If you get a bad abs sensor connection it can do this also.
