Inconsistent long term RAM data
• Check electrical installation in vehicle for non-certified third party equipment(*) and disconnect these. • Check for available software updates/campaigns. (*) The sensitivity, for equipment with high EMC radiation, is increased in an EMC emitting environment. This could for example be radar stations (airport/military), electric distribution plants, electrical switch towers, transformer stations, steel works, "electric" welding, etc.
What you'll see
• When the fault occured the EST system might have been restarted/reset. • A short time (<1 s) of slightly rough tag axle steering is possible.
System reaction
• System reset
