Engine Diagnostic Chart (cont.)

Rail pressure relief valve can’t be opened due to rail pressure; PRV error; rail pressure out of tolerance range; average rail pressure is outside the expected tolerance range

52347012

52355012

Rail pressure relief valve open; PRV forced to open; system reaction initiated, fault path indicating shutoff condition in case of open PRV; power reduction may result

Rail pressure relief valve open;PRV is open; PRV in rail is open; power reduction may result

Terminal 50: ECU receives a permanent signal; T50 start switch active for too long; Start information to starter T50 Switch erratic/defect

Internal Hardware Monitoring: the ECU detects a deviation of the target range of the power supply voltage of sensor output 3

Timeout Error of CAN-Receive-Frame TSC1AE; Traction Control

Timeout Error of CAN-Receive-Frame TSC1AR; Retarder 5236123

Reported supply over-voltage

Reported supply under-voltage 52361212

ECU Internal software error; power reduction may result.

Internal ECU monitoring detection reported error 52361214

Internal Hardware Monitoring: ECU CPU reset and cause is logged internally; no item created in error memory; software reset CPU, software visibility resets in DSM 5236130

Rail Pressure: fuel pressure in rail below target range dependant on engine speed; rail pressure disrupted, Positive governor deviation; maximum positive rail pressure deviation exceeded concerning set fuel flow; power reduction may result

Rail Pressure: fuel pressure in rail exceeds target range dependant on engine speed; rail pressure disrupted, maximum negative rail pressure deviation with metering unit on lower limit is exceeded
