What do these CODES mean?
The P1571 is a Traction Control Torque Request Circuit. The EBCM (Electronic Brake Control Module) sends a torque signal to the PCM as part of the traction control system, and this code is set when the PCM does not receive the signal for 3 seconds.
The P0801 is a Reverse Inhibit Solenoid Control Circuit. This solenoid prevents you from putting the transmission into reverse when it's moving, and the code is set when the PCM detects that the commanded state of the solenoid and the actual state does not match. The reverse solenoid may have failed.
Since these circuits are on separate connectors at the PCM, you should first check the connectors at the component end (EBCM and Reverse Lockout Solenoid). Make sure the connectors are clean with no corrosion.

And, how to fix? These are both showing C and H on the DIC.....
