5. Reinstall the terminator resistor and reconnect the battery.
If the ECU diagnostic tool is available, use it to verify that the ECU is transmitting CAN data. Refer to the
ECU documentation to identify and correct the error.
If another panel is available for testing, replace the panel to determine if the error is in the panel.
6.5 Diagnostic Trouble Codes (DTC)
CAN Diagnostic Trouble Codes are a pair of numbers, the SPN (Suspect Parameter Number) and the FMI
(Failure Mode Indicator). The SPN indicates the faulting subsystem and the FMI identifies the type of failure.
6.5.1 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 the ECU
documentation for supported SPNs. Table 2 describes some example SPNs.
Table 2: Example SPN
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
6.5.2 FMI
FMI codes are defined by SAE J1939-71. Refer to the ECU documentation for correct interpretation of the FMI
codes for a specific SPN. Table 3 describes each FMI.
Table 3: FMI Descriptions
FMI Description
0 Data valid but above normal operational range
1 Data valid but below normal operational range
2 Data erratic, intermittent or incorrect
3 Voltage above normal or shorted high
4 Voltage below normal or shorted low
5 Current below normal or open circuit
6 Current above normal or grounded circuit
7 Mechanical system not responding properly
