- P1260 code comes up and the only light on is airbag light. Nothing else, no mileage, no theft light, nothing and car will not start. I think I have tried every trick out there but think theres something else. Pats has me immobilized and key works for everything else except cranking car. Someone said I will have to get pcm/ecm flashed. The dealer is stupid because they want a lot of money and I have to get it towed. I don't understand why I shpuld have to pay for something I don't want in my car. I have always fixed all my vehicles and never had a problem like this. I used to love this car but now I hate it. Hopefully you can tell me how to fix this. Thanks
Well I attached the screenshot. But basically your vehicle thinks it's being stolen. So you have a problem with the anti-theft system. Now mechanics charge a fortune to do that and as you find out you're going to have to tow it somewhere so my advice would be to find a good locksmith many will work on those systems. And they will travel to your house and work on it there. Pray you can find a good locksmith in your area who can do that
Doesn't seem like the PATS because you say the odometer isn't working either and there isn't any Theft light.
Is the odometer showing dashes instead of the mileage or is it just not illuminating at all?
Dashes would point to the PCM not being able to communicate with the dash cluster.
Not illuminating at all would point to a power or ground issue to the dash (wiring or connections) or a faulty cluster.
Either one would set the PATS code because in both cases the PCM can't communicate with the cluster.
Either way, odometer dashes or no illumination at all can be caused by low battery voltage or a bad Ground Point connection where the negative battery cable is bolted to the body. So check your battery voltage, remove and clean up the negative battery cable Ground Point on the body, and maybe do some voltage drop tests on both the battery Positive cable and the battery negative cable.
