· The control unit recognizes a voltage
< 0.1 V at the "potentiometer nominal value" input (short
circuit to ground).
· The fault is stored after maximum 1 s.
Note: A
short circuit of the positive potentiometer voltage supply to the battery
voltage leads to the safety relay being switched off without the trouble code
being stored.
On fault recognition, the ETC function is switched off and
the ETC telltale is activated.
