69 523912 1 7-2-2
Physical range check low for burner dosing valve (DV2) downstream
pressure; Shut off regeneration.
When burner injector is actuated, the measured pressure does not rise
above 1250mbar abs (expected: about 2400mbar).
72 523912 3 7-2-2
Sensor error burner dosing valve (DV2) downstream pressure sensor; Signal
range check high.
73 523912 4 7-2-2
For engines < 4l:
Throttle valve error, Open load or short cut to battery, blocked valve or wrong
control signal for valve.
For engines with Burner T4i:
Pressure Sensor error after valve (DV2), lower limit reached.
74 523913 3 7-2-1
Sensor error glow plug control diagnostic line voltage; Signal range check
high.
75 523913 4 7-2-1
Sensor error glow plug control diagnostic line voltage; Signal range check
low.
76 523914 5 7-2-1
Glow plug control; Open load.
Water pump control (PWM) only TTCD 6.1/7.8.
77 523914 12 7-2-1 Glow plug control; Powerstage over temperature.
78 523914 3 7-2-1 Glow plug control; Short circuit to battery. Water pump control (PWM).
79 523914 4 7-2-1 Glow plug control; Short circuit to ground. Water pump control (PWM).
82 1235 14 2-7-1
CAN-Bus 2 = CAN_C reports Bus-error (for engines <8L and CV52 it is the
engine-CAN@250kbaud)
CAN Bus error passive; warning CAN C - engine CAN.
83 16 0 2-7-1 No detail information.
84 639 14 2-7-1 CAN-Bus 0: "BusOff-Status"
85 1231 14 2-7-1 CAN-Bus 1: "BusOff-Status"
86 1235 14 2-7-1 CAN-Bus 2 = engine bus "BusOff-Status"
87 16 0 2-7-1 BusOff error CAN.
88 102 2 2-2-3 Charged air pressure above warning threshold.
89 102 2 2-2-3 Charged air pressure above shut off threshold.
90 110 2 2-2-5 Defect fault check for absolute plausibility test.
92 110 0 2-2-5 Physical range check high for coolant temperature.
93 110 1 2-2-5 Physical range check low for coolant temperature.
96 110 3 2-2-5 Sensor error coolant temperature; Signal range check high.
97 110 4 2-2-5 Sensor error coolant temperature; Signal range check low.
98 110 0 2-3-2 High coolant temperature; Warning threshold exceeded.
99 110 0 2-3-2 Coolant temperature; System reaction initiated.
101 111 1 2-3-5 Coolant level too low.
106 598 2 3-2-5 Plausibility check for clutch.
121 1109 2 3-4-1 Engine shut off demand ignored.
