2013 Buick LaCrosse 3.6L (3 LFX) 6-spd (6T70)

C056D-3C

I got this 2013 Buick LaCrosse in with a few problem / DTC's and one being the Power Steering Control Module has a code C056D 3C. Can't find any problem with the Steering system. Codes cleared. Found a TSB {PI1294B} in SI for a Flash update. Once in TIS under the EPS it only shows configuration. But in SI it states there is no other action after Reprogramming. But yet you don't have a selection for programming. And if you click next it pulls up a popup for RPO {NJ1}. Per GDS2 mine is a RPO {NJ2}

There is also a selection for Variable Power Steering Control Module, it don't recognize the Part Numbers and i'm not sure if its even on this vehicle.

Am i Missing something or does this mean its up to date. I haven't done one on a GM before. Thanks

The cal with the green check mark is the latest calibration. Your current calibration "…" is several levels behind. Also, the latest calibration, "…" states that it addresses Code C056D

Brain you do have updated software available to address the error code. As Bob stated your current level is shown in the box to the right. You need continue with the "Next Button" do the software update then go back and do the module configuration.

Earlier on in the programming process, did you select “Replace and reprogram” or “Reprogram” ?

Brian, Just for future reference, it's usually best to always select "Replace and Reprogram" no matter what. I don't remember the technical reason why but as you found out, it's the only way it will work sometimes.

I hear you man. I have learned the same lesson over again more than once. Seems to happen more often the older I get. I just tell myself that it's because my hard drive is full so I keep overwriting old info with all the new info. :-)
