    P/N WHC Over Can - Enable / Disable

    Can anybody tell me what this is for? I cannot find the acronym WHC anywhere.

    We are installing a Hellcat into a RAM 1500 and I still have a Skid light that remains on. It seems that it is picking up an ABS Code U0140E-00 (Implausible Vehicle Configuration Data Received) I have a feeling this setting might have something to do with this.

    Other than that we now have a Hellcat Ram with no MIL thanks to HP Tuners.

    Got the VIN number so I can look up that exact truck? a U0140 means lost communication with body control module. Can't find the exact code you have but I may not be looking at the right vehicle.

    Full Code was U140E-00 (Implausible Vehicle Configuration Data Received). Sorry I added a U0140E-00 by mistake.

    I found the problem... Pretty obvious actually. I found it after I just updated another Ram 1500 that we installed a 6.4 Engine into. I used a stock 6.4 Jeep SRT8 tune and copied all the differences over to the Ram ECU and that skid light also came on. I then realized its definitely something I changed.

    I noticed under the GENERAL tab on engine it has engine size and engine displacement and in both cases with the Hellcat and the 6.4 it obviously changed to a 6.4 or 6.2 instead of the 5.7 in the RAM. It also said that if you change this to anything but stock it will disable the traction control...

    So now the Hellcat powered RAM is running MIL free completely!!

    It disables it with no repercussions or does it trigger a light or fault? Regard to the traction control part.

    I'm very impressed. We have talked about doing this but haven't yet.
