| Read out fault memory |
|
| Prerequisites: |
|
- Vehicle at standstill
- Turn system selector switch to EFR position (see electrical key)
- Switch drive switch off and on again (drive switch to step 2, drive position)
|
|
| Fault output via EFR fault lights (yellow): |
|
- Hold down check key (red) for at least two seconds. The fault is output as a Flashing code.
|
|
| Notes: |
The flashing code output is restricted to the most recent fault before "Drive switch on". This means: to read out a fault which occurs during the journey, the vehicle must be stopped as soon as possible at a suitable point, engine and drive switch off, to call up the Flashing code output as described above.
