Diagnostic depth
Detection
The supply voltage for the control unit is too low. The fault code is activated when the supply voltage falls below 8,5 V for more than 60 s. The control unit switches off when the supply voltage falls below 6 V (+/- 0.5 V).
Possible cause
The control unit is incorrectly connected to the 24 V supply voltage.
