No start P1260-FF B2141-FF C1306
 

2007 RX8 GT with AKE (card key) system.
Parked the car last Tuesday and it had been fine, Friday I pushed it into the garage from the driveway (about 30 feet, didn't want to start it and worry about warming it up or shutting it off cold) to change coils, plugs and wires (since the car is new to me I have a record of them being done).
Then later in the day my switchblade key arrives and I make an attempt at programming it (via FORscan), wasn't able to but before heading inside I turn the key to the on position and check that the KEY light turns green and that nothing is screwed up, all good no problems.
I then push the car out of the garage (again not wanting to start it for a couple of seconds) leave it parked in the driveway for the weekend.
Today I push it around a bit more (need to shuffle some other cars into and out of the garage), come time to take it for a drive this afternoon, no start, no cranking, nothing.
Battery is new (and show no signs of a low battery, all lights, radio work).
KEY light is now flashing red, so is the security light (car symbol with the key in it), check engine light is on along with steering wheel light and DSC is flashing (I'm going to assume steering wheel and DSC is to do with the C1306). I have tried disconnecting the battery (currently I have it disconnect and on the charger just in case), I assume the C1306 is on due to maybe disconnecting the battery and not being able to start the car and turn the wheel lock to lock.
Card key (of which I only have the one) still functions 100%, remote on it works, AKE features (i.e. button on door handle works) and the ignition appears to recognize it (the ignition unlocks and can be turned also when doing so the light on the card flashes). I have tried with the emergency blade key and get the same problem.
I have also tried clearing both the codes in the PCM module and the RKE module, they appear to either not be clearing or come right back after a key cycle.

P1260-FF - Theft detected vehicle immobilized - I'm guessing something triggered the car to make it think it was being stolen - too much just rolling it around in the driveway?
B2141-FF - RKE could not receive PCM ID from PCM - Maybe since the PCM thinks the car is being stolen its locked down and wont pass along the ID?
C1306 - Steering wheel no center found during initialization - I'm assuming if I could get the car to start and turn lock to lock it might go away.

I have double checked all the fuses - they are all good, I currently have the battery disconnected and on a charger just in case, any other ideas?

So I checked the flash codes:
I get a solid security light for a min or so and then two quick flashes, pause, 2 quick flashes, pause and so on. I assume this is "Communication error between the keyless control module and the PCM (data transfer error)" I haven't touched any of the questions physically, so I don't know why all of sudden there would be a problem. I will double check all of the fuses again.
I was really expecting "∩∩__∩∩∩______ = ID number data in the PCM and the keyless control module do not match." but maybe that isn't the case.
So I either screwed something up and the RKE or PCM is somehow locked up and wont communicate with each other (though other programming functions for them work, i.e. I can toggle autolock on and off for the RKE module and run full self test diagnostics on the PCM), I have some weird coincidence connection issue or somehow I have blown a fuse or something.

I am facing the same problem. Could you resolve this issue? My car is not starting anymore.

I am facing the same exact issue.. Could you resolve this problem without towing the vehicle to the dealer?

Sadly no, full explanation was that somehow the security module had lost all its info and had to be reprogrammed (rebuilt) using factory defaults. I suspect if you had access to the correct diagnostic tool and subscription service you could do it at home.

Good news
At least you didn't have to replace it. I hope I will be the same case. I am worried about a unit malfunction.

Rx8 will nott start
 

can u tell me what was done to solve your problem???

Yes m having the same issue and need to get it fix

How did you start having the issue and what have you tried?

If you've used FORscan and reset the RKE module, you NEED to have two separate keys (physical key with chip in it) registered to be able to start the car. Same goes for AKE keys; you need two of them registered.

Car started having issues when we tried changing the plugs. We pushed car from one point to the next in the yard, then it was towed to a next spot

from there there is just not cranking
Remotes are working fine but keys won’t crank

what is FORSCAN ?
Is it a scan tool ??

also what are u saying ?? That I should programmed two new keys separately from what is there already ??

if yes should I delete those that are there ??

if u got what’s up u can message me at 767-245-4413


thank you

If you haven't used FORSCAN, then you shouldn't need to worry about it.
FORSCAN is a scanner tool and it has additional features allowing you to modify some modules in your car such as configuring/programming the remotes and keys.

Are you seeing the immobilizer light on your dash? is that just flashing regularly, and do you get a green KEY light when you turn your ignition key/knob? If all of that is true, you could have a dead starter motor. Try listening for any sounds coming from your car when your try to start your car.
