Thats what tune ecu is for I've never even tried my code reader on my bike its not like it can balance the throttle bodies or handle the ISCV it can't clear the adaptives. So it stays in the truck where its useful.
this vehicle should have an obd connecter
i bought a bosch reader has read codes ,clear codes and live data .
this may or may not read a tranny code but it might clear a tranny code cost was around $100 from orielly
or u can on this vehicle only u can remove 1 bat terminal and touch it to the other this may clear codes.
