My car has set these codes off a few times before, but I've reset them and it hasn't continued until now. After reseting them multiple times they keep reappearing along with the ABS light and Traction control light!
P1571 ASR Desired Torque
P1644 Delivered Torque Output Circuit
What could be the cause of these codes?!? THANKS!!!!
i have been told to check the connections and ground on the EBTCM which i believe is located behind your rear axle in the center of the car. hopefully some others will have incite also. mine also says 28 TCS No Comm.
