SECTION 3 - CHASSIS & TURNTABLE
Possible Cause
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- Urea Pump A04
2- SCR Heater A05
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- 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 run-
ning, diagnostic
Suspected components:Fan, Wiring harness
Battery voltage above warning threshold
(~38,9Volt), Short cut to battery possible.
Battery voltage below warning threshold,
Short cut to ground
If Batteryvoltage (Ubatt_U) > 17V or 31V for
mor than =0.5sec a warning is generated
Battery voltage above warning threshold
Action
Check wiring harness and connected loads on
pins A88, K57.
Check wiring harness and connected loads on
pins A04, A05.
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.
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 alternator.
Check wiring harness and connected alternator.
Check wiring harness and connected alternator.
