Diagnostic Trouble Codes (DTC)
CANbus Diagnostic Trouble Codes are a pair of numbers; the Suspect Parameter Number (SPN) and Failure
Mode Identifier (FMI). The SPN indicates the faulting subsystem and the FMI identifies the type of failure.
Typical SPNs
Standard SPN codes are defined by SAE J1939-71. Not all standard codes are provided by ECUs.
Manufacturers may add additional SPN codes beyond the codes identified in J1939-71. Refer to ECU
documentation for supported SPNs.
SPN Description
51 Throttle Position
91 Accelerator Pedal Position
94 Fuel Delivery Pressure
98 Engine Oil Level
100 Engine Oil Pressure
110 Engine Coolant Temperature
111 Coolant Level
FMI
FMI codes are defined by SAE J1939-71. Refer to ECU documentation for correct interpretation of FMI
codes for a specific SPN.
