Wrangler 2012 Evo All with Advanced Keys push to start starter P0513 immobiliser fault after starting

Question

There's a 2012 Wrangler, the Evo All works fine, the remote start and starting with Advanced Keys push to start,keyless entry works. But when I start the car with start button, check engine light comes on and the car is still running. The fault is P0513 (Incorrect immobiliser key). MUX wire not connected. A3-Key Bypass turned on. Can anybody help me how can I fix this fault?

Answer 1

What happens if you just start it noramlly with a programmed key? Does the fault still set?

Comments

If I clear DTC and start with key, it doesn't come. But next time I start the car with button the fault comes on again. If I don't clear DTC it's still set.

I was thinking that...I have seen that code before on european wranglers.

We have not tested our solution on EU built jeep wranglers. The computers are not programmed the same.
