ECU hardware memory failure in program- or calibration flash, internal RAM, external RAM, EEPROM
1. Check electrical installation in vehicle for non-certified third party equipment(*) and disconnect these. 2. Check for available software updates/campaigns. 3. If the problem remains (the DTC reappears after erase), after the above actions, replace the ECU. (*) 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
The DAS system will stop sending CAN messages and will not engage discrete outputs for solenoids.
