Does anyone know what this code is "U1301" It showed up on my hypertech today. I also get "B0229" which seems to be a common one because it showed up with the search function. Just curious. The SES light is not on.

Did you not get the code listing with your programmer?

[H2 Doberman]

No, was I suppose to get one.

[H2 Doberman]

Thanks phil! I don't think that it is anything terminal. Might just be something that the programmer caused with the battery.

What is HVAC actuator circuit? because I got the same code too.

B0229 means that at one time your HVAC recirculation door was out of calibration due to a misaligned door or linkage, broken linkage, missing seal, obstruction, or loose wiring connector. If it has corrected itself, the code will go away after 100 ignition cycles, or erased by a scan tool.
