What does FMI 14 mean for Volvo Vecu?
FMI 14 The vehicle control unit (VECU) does not receive information from the adaptive cruise control unit (ACC) via the SAE J1939 data channel. Breaking or partial damage to the data channel. The ACC unit may be faulty.
What does FMI mean on a new car?
FMI 1 The vehicle control unit receives a signal from a sensor with a voltage below 3.1 V (corresponds to 9.7 bar) for the older version and below 2.6 V (corresponds to 8.0 bar) for a newer version. Air pressure below normal. Air leaks, clogged, damaged air lines or air suspension components.
What does FMI 4 mean on a Honda Accord?
FMI 4 The voltage of the signal to the control unit from the accelerator pedal sensor is less than 0.4 V. The break in the power or signal wire. Shorting the signal wire to ground. Defective or oxidized contacts in the connectors. Accelerator pedal position sensor may be faulty.
What does the PID stand for on a Volvo?
The PID consists of a number that designates a parameter (value) to which the fault code relates (oil pressure, for example). The same as the PID, but this is a Volvo-specific parameter.
When does a Volvo engine fault code become inactive?
Some fault codes become inactive when the engine is stopped. Start the engine to check whether the fault code is still inactive with the engine running. After an action with the connector. Put the connector back. Check if the fault code becomes inactive.
What is FMI for a Volvo LCM lamp?
FMI 3 LCM output voltage on the lamp is equal to or higher battery voltage. Shorting the wires between the LCM unit and the lamps at a higher voltage or faulty lamps. FMI 4 The output voltage from the LCM unit to a lamp is less than 2 V.
What is the fault code for a mid 128 engine?

How does the Diagnostic Code list module identifier ( mid ) work?
Module Identifier (MID) The module identifier (MID) identifies the electronic control module that detected the fault. Each electronic control module on the machine has a unique MID. Use the following chart in order to match the MID for each diagnostic code to a specific electronic control module.
How is the failure mode identifier ( FMI ) defined?
Failure Mode Identifier (FMI) The codes for the Failure Mode Identifier are defined by the SAE standards. The following list contains a CAT version of definitions. The diagram that follows will help you understand the use of FMI with sensors. Illustration 1 g00493694 Failure Mode Identifier and Message Center Displays FMI “Failure Description”
