Illegal software operation
After a system reset (e.g. using the ignition key), the system should work normally. • Check for available software updates/campaigns. • Check electrical installation in vehicle for non-certified third party equipment(*) and disconnect these. (*) 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 ESTA system might have been restarted/reset. • A short time (<1 s) of slightly rough tag axle steering is possible.
System reaction
No system-reaction text recorded.
Diagnostic depth
The ESTA ECU software has executed in an unexpected/illegal manner.
• Software flaws • Exposure to extensive electro-magnetic radiation • Non-certified third party equipment is installed (*) (*) 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.
