Codes p1260:00-2B, p1622:00-2B, and b2900:E0, Anti-theft system mismatch?

Do you have the Autel MaxiIM IM608PROIIKPA, MaxiIM IM508S, and MaxiIM KM100? These are designed to program automotive keys and fobs.

P1260:00-2B - Theft Detected, Vehicle Immobilized
P1622:00-2B - Immobilizer ID Does Not Match
B2900:E0 - Vehicle Configuration Mismatch

Please let me know.

I have the Maxisys ms908p, have used it so many times in programming does.

My only worry is because my key tool max is bad, else I could sort exactly out the problem. Could I have a bad anti-theft antenna?

Because I used super to to configure the chip to 4d 63 id is this the correct transponder for this 2010 model?

I would do a hard system reboot and then try to program the keys again.

What was the original problem, lost keys? Please go over this guide and get back to us.

Yes, lost keys.

Okay, then here is what they say about the Maxisys ms908p.

It's important to note that key programming functions are not universally compatible across all vehicles.

I would try the hard reboot and try again.

I have tried the hard reboot. But I am sure the Immobilzer antenna is faulty, it’s a 4 wire pins, can you get the signals.

Also will think of replacing.

Good call, if the antenna wiring is broken the system will not receive the signal.

I wish I could test the wires.

Hi Ken, after close verification, the antenna anti-theft works very well.

May I have a diagram of the Anti-theft indication with modules like the PCM it runs through. I noticed it goes through the instrument cluster as well.

1FMCU9EG6BKA06593 This vin is the Chassis, on the left windscreen.

1FMCUOD76AKB86749 This Vin is the current ecu found in the car, meaning the previous technicians had replaced it.

In order to be on track, if I may have the immobilizer pin out for this 2 units I can verify where the mismatch is coming from.

It seems like the PATS transceiver module is bad. Here is the wiring diagrams for it. Check out the images (below).

I had double checked this, the transceiver is ok, actual problem is the main pcm has been replaced, the previous was a 2010 and the new is a 2011, I have an error code of VIN mismatch and key code mismatch.

I wonder if the change could be the problem.

Yep, that will do it, that would have been good info to have.

Hi Ken, please can you help me with the full network diagram for this car, so I can verify certain modules which are not on the network system. Please!
