Warning: Only memory codes can be erased!

Bosch · OBD1300 Scan Tool

What does Only memory codes can be erased! mean?

This message appears when you attempt to erase codes. It informs you that only 'memory codes' (Continuous Memory Codes) can be cleared without repairing the fault. KOEO and KOER codes require the fault to be fixed first.

Common Causes

  • Attempting to erase codes that are not 'memory codes'.
  • The vehicle has active faults (KOEO or KOER codes) that cannot be erased until repaired.
