*RCH = Passenger Compartment Heating Resistors
ET111SET NUMBER OF PASSENGER COMPARTMENT HEATING RESISTORS
STATUS DEFINITIONThis status indicates that the injection computer is blocking any change to the number
of passenger compartment air heating resistors active (active ones are not cut off, but
no more can be added). This freeze in the number of heating resistors is in response to
vehicle needs (availability of power, need for torque etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant temperature
> 80
°C
YESDepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required).
Status ET111 becomes YES when the number of activated passenger compartment
heating resistors is set by the injection computer.
NODepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer sets the number of activated passenger
compartment heating resistors (no more or no fewer than required). Status ET111
becomes NO if the number of passenger compartment heating resistors engaged can
be freely controlled by the UCH.

ET112PASSENGER COMPARTMENT HEATING RESISTOR CUT-OFF
STATUS DEFINITIONThis status indicates that the injection computer is blocking activation of all passenger
compartment air heating resistors due to vehicle needs (availability of power, need for
torque, injection defect mode or heating and ventilation etc.).
Conformity check: Engine stopped and ignition on, or engine running and engine coolant temperature
> 80
°C
YESDepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer cuts off the passenger compartment heating
resistors.
Status ET112 becomes YES when the passenger compartment heating resistors are cut
off by the injection computer.
NODepending on the requirements of the injection system (e.g. torque reduction, power
requirements), the injection computer cuts off the passenger compartment heating
resistors.
Status ET112 becomes NO when the passenger compartment heating resistors can be
freely controlled by the UCH.
