Do as follows to read off the fault code:

1 Press the diagnostics button.

2 Release the diagnostics button and note down the fault that is flashed out.

3 Repeat items 1–2. A new fault code will be flashed out if more faults are stored. Repeat until the first fault code reappears.

NOTICE! When the first fault code reappears, all fault codes have been read off.

If the diagnostics button is pressed after the fault has been rectified and the fault codes have been erased, code 1.1 “No fault” will be displayed.
