Have you had an issue starting your Fiat 500? There is a new Fiat Technical Service Bulletin (Fiat TSB) that has been released announcing a software update that fixes starting issues for owners of 2012 - 2013 Fiat 500 and 500 Abarth models. The symptoms are an occasional cranking no start condition. Fiat 500 owners may also experience an engine that sounds like it is freewheeling or has no compression. In most situations, this is normally resolved by simply trying to restart the car.
Additionally, a small number of Fiat 500 owners may experience a Malfunction Indicator Lamp (MIL) illumination with a P2299 (Brake Pedal Position/ Accelerator Pedal Position Incompatible) code being set.
The fix involves reflashing the Fiat 500 Powertrain Control Module (PCM) with revised software. The reflash also enhances cold weather starting performance.
Note this is for 2012-2013 Fiat 500, 500T Turbo and Fiat 500 Abarth models equipped with the 1.4L MultiAir and MultiAir Turbo engines (sales code EAB or EAF).*
