Fiat Software Fix
This bulletin applies to 2013 Fiat 500/Abarth vehicles equipped with a 1.4L engine and built on or before June 24, 2013.
A “small number” of customers may experience a MIL on. The technician may find the following DTCs set: P0456 (EVAP system small leak) and P0128 (thermostat rationality). Updating the PCM software with release 14.01 or higher will correct the condition.
Using a scan tool (wiTECH) with Smart Cable 410 and appropriate diagnostic procedures available in TechCONNECT, verify that all engine systems are functioning as designed. Record and address any other DTCs that may be present before programming.
