Conditions:
- number of faults = X
- engine temperature > XX°C (XX - Measured values group XXX field X)
- intake air temperature > X°C (XX - Measured values group XXX field X)
- catalyst temperature > XXX °C (XX - Measured values group XXX field X)
- on-board voltage > XXV (XX - Measured values group XXX field X)
- engine speed = X
- accelerator pedal - released (XX - Measured values group XXX field X)
connect with the control unit XX - engine
XX - Basic settings group XXX
activate default settings
wait
required values
field X = ADP-OK (may take several minutes)
back
Start the engine, engine speed = idling
XX - Measured values group XXX
required values
field X > XXX °C (temperature of exhaust gases)
XX - Measured values group XXX
required values
field X = XXXXX
field X = XXXXX
XX?XX = heating of lambda probe(s)
XXX?X = readiness for operation
XXXX? = lambda control
upon achievement of values - continue
XX - Basic settings group XXX
depress and hold - brake pedal + accelerator pedal
the control unit increases the engine speed
required values
field X = XXXX rpm
field X > XXX °C (catalyst temperature)
field X = RX-SX-OK (may take several minutes)
upon achievement of values - release - brake pedal + accelerator pedal
back
engine speed = idling
XX - Basic settings group XXX
depress and hold - brake pedal + accelerator pedal
the control unit increases the engine speed
required values
field X > XXX °C (catalyst temperature)
field X = RX-SX-OK (may take several minutes)
upon achievement of values - release - brake pedal + accelerator pedal
back
engine speed = idling
XX - Basic settings group XXX
depress and hold - brake pedal + accelerator pedal

required values
field X > XXX °C (catalyst temperature)
field X = CAT-RX-OK (may take several minutes)
upon achievement of values - release - brake pedal + accelerator pedal
back
XX - Basic settings group XXX
depress and hold - brake pedal + accelerator pedal
the control unit increases the engine speed
required values
field X = TEV-OK (may take several minutes)
upon achievement of values - release - brake pedal + accelerator pedal
XX – error memory
desired condition: number of faults = X
XX - Measured values group XXX
required values
field X = XXXXXXXX (readiness)
xxxxxxx? = catalyst
xxxxxx?x = heating of catalyst
