Signal Name Description Condition Impact
Dual Power Pump (DPP) ECU was reset to factory mode due to memory version corruption.
DPP ECU reset to factory state due to memory version corruption
Steering assist may be affected
Dual Power Pump (DPP) ECU memory read or write error detected.
All data written to DPP ECU memory is immediately read back to ensure accuracy. If either the read or write operation is in error then a fault is declared
Steering assist may be affected
Dual Power Pump (DPP) flash write failure detected.
DPP double bits error correction code (ECC) error detected in data-flash or failure to write to data-flash/program-flash
Steering assist reduced
Dual Power Pump (DPP) ECU memory checksum fault detected during the Cyclic Redundancy Check (CRC).
DPP ECU data written to memory/Data-flash on previous cycles is checked against CRC and is not correct
Steering assist reduced
Dual Power Pump (DPP) power reduced due to loadshed active.
DPP loadshed level is any value other than DPP_LOADSHED_NONE_SNA
Steering assist reduced
Dual Power Pump (DPP) assist halted due to safety critical data being corrupted.
