Loader runs fine but the {!} is flashing on the instrument cluster as well as the monitor. Code came up for 2 different operators but, went away as soon as they brought it to us in the truckshop at the foundry I work for. Any ideas???
Are you sure you don't mean "DPF"...? If this is a TIER 4 machine it may have exhaust aftertreatment fitted so that would make sense. A Serial Number would be a good start.
