FLASH CODE:
47
DDR DISPLAY:
FUEL PRESSURE HIGH
SAE J1587 CODE:
PID: 94 FMI: 0
Indicates that the Fuel Pressure Sensor (FPS) has detected that the engine fuel supply pressure has exceeded the
recommended safe operating range.
FLASH CODE:
48
DDR DISPLAY:
FUEL PRESSURE LOW
SAE J1587 CODE:
PID: 94 FMI: 1
Indicates that the Fuel Pressure Sensor (FPS) has detected that the engine fuel supply pressure has dropped below
the recommended safe operating range.
FLASH CODE:
52
DDR DISPLAY:
ECM A/D CONVERSION FAILURE
SAE J1587 CODE:
SID: 254 FMI: 12
Indicates that the DDEC III ECMs internal Analog to Digital (A/D) Convertor device has malfunctioned. Intermittant
diagnostic conditions of this type can be caused by faulty external electrical system.
FLASH CODE:
53
DDR DISPLAY:
NONVOLATILE MEMORY DATA INCORRECT
SAE J1587 CODE:
SID: 253 FMI: 2
Indicates that the ECM upon startup has been unable to read a valid copy of a engine data record (calibration, faults,
or accumulators) stored in nonvolatile memory.
FLASH CODE:
53
DDR DISPLAY:
NONVOLATILE MEMORY FAILURE
SAE J1587 CODE:
SID: 253 FMI: 12
Indicates that the ECM was unable to update an engine data record (calibration, faults, or accumulators) stored in
nonvolatile memory.
FLASH CODE:
54
DDR DISPLAY:
VEHICLE SPEED SENSOR FAILURE
SAE J1587 CODE:
SID: 084 FMI: 12
Indicates that during an ignition cycle the vehicle speed that is measured by the Vehicle Speed Sensor (VSS) is less
than the expected value for the current engine RPM. This diagnostic condition is typically:
(1)
open sensor signal circuit
FLASH CODE:
55
DDR DISPLAY:
PROPRIETARY DATA LINK FAIL (MASTER)
SAE J1587 CODE:
SID: 248 FMI: 8
Indicates that the Master ECM of a multi-ECM configuration (12, 16, or 20 cylinder engine) has stopped receiving
status information from one or both receiver ECMs.
FLASH CODE:
55
DDR DISPLAY:
PROPRIETARY DATA LINK FAIL (RECEIVER)
SAE J1587 CODE:
SID: 248 FMI: 9
Indicates that the Receiver ECM of a multi-ECM configuration (12, 16, or 20 cylinder engine) has stopped receiving
fueling information from the Mater ECM.
