A control module reports that its non-volatile memory has been reset (lost adaptions, lost coding, lost trip counters). Often appears after battery disconnects, voltage drops below operating limit, or module reflashes.
Medium severity. Can I keep driving?It depends on which control module has dropped out. If it affects the engine, brakes, or steering, do not continue your trip: call for roadside assistance.
Symptoms
- Multiple warning lights may illuminate
- Affected modules may go into limp mode or shut down
- Specific functions inoperative depending on module
- Diagnostic tools may show communication faults
Most likely causes
- Battery disconnected or low voltage event
- Module reflash or coding change
- Gateway module routing CAN messages incorrectly
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: easy
What each character of U0600 means
- U: Communication network
- 0: Generic code: same on every make
- 6: Subsystem depends on the code range
- 00: Specific fault in that system
