Table 3-16. Deutz Engine Fault Codes
Description
@ engines < 4l:
Throttle valve error, Open Load or Short cut
to Battery, blocked valve or wrong control
signal for valve.
@ engines with Burner T4i:
Pressure Sensor error after valve (DV2),
lower limit reached.
Overload at Pins O_V_RH2x: A01, K74,
K91. Components on A01, K74, K91 cannot
be activated.
Internal ECU power stage switched off.
Short circuit to battery error of actuator
relay
2. Components on Pin A88, K57 cannot be
activated.
Internal ECU power stage switched off.
Short circuit to ground actuator release 3
Overload at Pins O_V_RH3x: A88, K57
Short circuit to ground actuator release 4.
Overload at Pins O_V_PCV: A90
Short circuit to battery error of actuator
relay
2. Components on Pin A04, A05 cannot be
activated.
Internal ECU power stage switched off.
Possible Cause
The sensed raw voltage value is below the
mini- mum threshold.
Suspected components:
1- Pin K91:
Clutch switch, Brake switch, Engine brake
demand, Regeneration activation, Parking
brake, Gearbox N, Fan control 1
2- Pin K74:
Boost air cooler bypass or electrical fuel pump
relay, Fan control 2/fuel valve for flame
star
Suspected Components:
1- Lamps K57: Warn Ash Charge, Diagnostic,
Warn Coolant Temp/Level, Warn Oil,
Warn Boost Air, Warn Air Filter, Warn Water in
Fuel, SCR, Regeneration, Engine
Running.
2- Relay Preheat A88
3- Exhaust Flap A88
Suspected components:
1- Pin A88:
Preheat relay, Exhaust flap
2- Pin K 57:
- control lamps:
- OBD, preheat lamp, warning temp., warning
oil, maintenance lamp, regeneration
indicator, alternator management, engine
running, diagnostic
Suspected components: Fan, Wiring harness
Suspected Components:
1- Urea Pump A04
2- SCR Heater A05
Action
The sensed raw voltage value
DPM_uRawBrnDVDsP is above the minimum
threshold
DPM_SRCBrnDVDsP.uMin_C
@ CRT < 4l: check throttle valve
@ engines with Burner T4i: check back-
pressure valve
Threshold for error detection is an internal ECU
threshold.
Check wiring harness and connected loads on
pins A01, K74, K91 and/or reflash ECU.
If error is still present, exchange ECU.
Check wiring harness and connected loads on
pins A88, K57.
Threshold for error detection is an internal ECU
threshold.
Check wiring harness and connected loads on
pinsA88, K57.
If error is still present, exchange ECU.
Threshold for error detection is an internal ECU
threshold.
Check wiring harness and connected loads on
pin A90.
If error is still present, exchange ECU.
Check wiring harness and connected loads on
pins A04, A05.
