Anyone know what these symbols mean on my dash monitor. SPN:0 and under it FM1:0 The symbols flash on and off..
Your display is showing you have a active fault code. SPN stands for Suspect Parameter Number and FMI stands for Failure Mode Identifer. Usually after the SPN you will have a three or four digit number and after the FMI it will be a one or two digit number. Once you have the numbers you could call your dealer and he can tell you what the fault is. Hope this helped.
