filter upstream temperature sensor circuit is stored, check if it is in short circuit to the + 12 V or in open circuit
using this command.
Procedure:
– Run command AC239 Particle filter temperature sensor fault finding in the presence of the one of these
two faults DF999 Particle filter downstream temperature sensor circuit and/or DF1000 Particle filter
upstream temperature sensor circuit.
