I have a 2012 wrangler 4 door with the 6 speed manual. The traction control light was coming on and would go into limp mode more more than 3000 RPM I would shut it off and restart and it would be good for a bit longer. Now its on all the time. Replaced all 4 wheel speed sensors and a cam shaft sensor that was throwing a code and still have the same issue. Took it to the Jeep dealer and they said it was the ECM and they couldn't connect to it so cant doing anything until I replaced it. It now has a new ECM and still in limp mode and the traction control light is still on.
codes it was showing.
P0345 camshaft sensor circuit bank 2 sensor 1
P0103 Mass air flow sensor A circuit high
C121C Torque Request signal denied
I really don't know what to do at this point. In Eastern Washington.

Did the shop that diagnosed it do the replacement?

When you swap the PCM is there a relearn procedure for odo and VIN? Also, OP, did you clear codes and re-scan after swaps?

No the dealer couldn’t get one and no time frame to get one. Ordered online with it programmed to my vin

How do I do that?

Should be plug and play. You can try disconnecting the battery cables to reset.

Maybe you got a bum unit.

No, as long as it is programmed for the correct vin, it should be plug and play. I ordered a replacement from allcomputerresources.com years ago and it was plug and play. They just ask for your vin at checkout.
