Freightliner Diagnostic SPN. MID, PID, SID, FMI - DTC (1)

What areSPNandFMIcodes?

FMIs are used in conjunction with SPNs to provide specific information that pertains to a Diagnostic Trouble Code(DTC). FMI may indicate that a problem has been detected with an electronic circuit or electronic component. FMI can also indicate that an abnormal operating condition has been detected.

J1939problems?

Switch off the ignition and disconnect the batteries. Set the multimeter to resistance and place the wires between CAN + (pin C) and CAN - (pin D).

CAN + and CAN - will be tested separately. Switch on the ignition and connect one test lead to ground and the other wire to CAN + (pin C) or CAN - (pin D).

PARAMETER IDENTIFIERS (PIDS)

Parameter IDs or PIDs are numbers and names used to identify the displayed data. So think if the PID is in terms of "readings" such as oil temperature, coolant level, distance traveled, engine rpm and so on. PID is a J1708 term and PID is 0 to 511.

FAILURE MODE ID (FMI)

Now that we have defined the MID (Component) and PID (Data Types), we can talk about Failure Mode Identifiers (FMI). Every diagnostic trouble code (DTC) found will have an FMI. This code is set by the ECM detecting various problems such as too high voltage, under voltage, incorrect resistance, etc. So, here is a list of possible FMI values:

0 = data valid but above normal operating range, most severe

1 = data valid but below normal operating range, most severe level

2 = data is inaccurate, intermittent, or incorrect (rationality)

3 = voltage above normal or short circuit to high voltage source

4 = voltage below normal or short circuit to high voltage source

5 = undercurrent or open circuit

6 = Above current or grounded circuit

7 = Mechanical system not responding or not adjusted

8 = abnormal frequency or pulse width or period

9 = Abnormal refresh rate

10 = Abnormal rate of change

11 = The fault code cannot be identified

12 = Bad smart device or component

13 = Calibration failed

14 = Special instructions

15 = Data Valid but Above Normal Range: Least Severe Level

16 = Data valid but above normal range: moderately severe

17 = Data Valid but Below Normal Range: Least Severe Level

18 = Data valid but below normal range: moderately severe

19 = Received network data in error: (multiplexed data)

20 = high data drift (high level of rationality)

21 = Low data drift (low level of rationality)

22 to 30 = Reserved for SAE Assignment

31 = Condition exists

SUBSYSTEM IDENTIFIERS (SIDS)

Now that we understand that MID is a component, for example an engine, it can be broken down into subsystems. Each subsystem has its own set of SIDs. For example, MID 128 (engine) might have SID 6 for injector number 6. However, SID 6 on Mid 136 (transmission) is for solenoid valve C6.

We have put together a PDF containing all the SIDs for J1708. It's broken down into MID, giving you this list:

Common SID

Engine Safety Identifiers (MID = 128, 175, 183, 184, 185, 186)

Transmission Security Identifiers (MID = 130)

Brake Safety Identifiers (MID = 136, 137, 138, 139, 246, 247)

We've also compiled a list of smaller subsystems, which includes:

Dashboard Security Identifiers (MID = 140, 234)

SID of vehicle management systems (MID = 142)

Fuel system SID (MID = 143)

Cab climate control safety identifiers (MID = 146, 200)

Suspension SID (MID = 150, 151, 152, 153)

Vehicle Security Identifiers (MID = 162, 191)

Vehicle Security Identifiers (MID = 163)

Tire Safety Identifiers (MID = 166, 167, 168, 169)

Special SID trap systems (MID = 177)

SID of refrigerant management systems (MID = 190)

SI for tractors / trailers (MID = 217, 218)

SID for collision avoidance radars (MID = 219)

Transmission Retarder Safety Identifiers (MID = 222)

Vehicle Sensors for Data Coverter Security Identifiers (MID = 178)

Restraint System Security Identifiers (MID = 232)

Road Image Forwarding Processor Security Identifiers (MID = 248).
