Customer Question

I have a 2012 Volvo 780 VNL-- just got a fault code of 5443 with a fm of 13. First event and last event are blank I know the fault code is for the Ecuador and that it is showing out of calibration I am in California going to Ohio with a very very tight run and then 4 days off. What, if any, risks will I incur to drive to Ohio and then get it repaired?

Hi my name is***** will be glad to help. It would be a coin toss as at some point the ECM will derate your engine forcing your to address this. As I am sure you know it will likely happen at 2 am when no one is available to work on it. Let me know if you need more help
