This identifier indicates the type of failure that is associated with the component. The FMI has been adopted from the SAE practice of J1587 diagnostics. The FMI follows the parameter identifier (PID) in the descriptions of the fault code. The descriptions of the FMIs are in the following list:

0 - The data is valid but the data is above the normal operational range.

1 - The data is valid, but the data is below the normal operational range.

2 - The data is erratic, intermittent or incorrect.

3 - The voltage is above normal or the voltage is shorted high.

4 - The voltage is below normal or the voltage is shorted low.

5 - The current is below normal or circuit is open.

6 - The current is above normal or the circuit is grounded.

7 - The mechanical system is not responding properly.

8 - There is an abnormal frequency, an abnormal pulse width, or an abnormal time period.

9 - There has been an abnormal update.

10 - There is an abnormal rate of charge.

11 - The failure mode is not identifiable.

12 - The device or the component is damaged.

For example, in the diagnostic code: 110 - 3, the 110 is the CID, in this case, the coolant temperature sensor. The 3 is the Failure Mode Identifier (FMI), in this case, voltage high.


Assorted ceramic and electrolytic capacitorsThis is the unit of electrical capacitance, named after the physicist Michael Faraday. You can read more about Faraday here.

One farad is defined as the capacitance of a capacitor which, when charged with one coulomb of electricity, there is a potential difference of one volt across its terminals.

Another way of putting it is the capacitance which, when charged to a potential difference of one volt, carries a charge of one coulomb.

A coulomb is equal to the amount of charge (electrons) produced by a current of one ampere (A) flowing for one second.

You should note that a farad is a relatively huge amount of capacitance, and you will most likely never come across such a large capacitor in automotive engineering.

More commonly, you will encounter capacitors with values measured most commonly in microfarads, µF, (millionths of a farad, or 1x10-6).
For example, the capacitor used in the time delay circuit exercise in the Basic Electronics Learning Unit has a value of 2200µF.

Less commonly, you may encounter capacitors with values measured in nanofarads, nF,  (thousand millionths of a farad, or 1x10-9)

AG Block electronically managed engine showing bank of fault switchesIn the context of electronic engine management, the CP Fitters' section is equipped with bench mounted petrol and diesel electronically managed engines.

A lot of these engines are provided by AG Block, and, to assist with training, they are equipped with a bank of 10 switches which can be used to put faults into the electronic engine management system.

The fault switches are in the 'OFF' position when they are down (inactive and no faults in system).

They are active (putting a fault into the system) when they are up.


Feeler bladesMeasuring blades used by cp fitters to accurately measure small distances between components. For example, feeler blades are used when setting valve clearances in an engine:

A ferrite is a non-metallic material that has the ferromagnetic properties of iron.

A ferrite is a non-conducting, ceramic material - it is an insulator.

It is often used instead of iron in small transformers.

A metal containing iron. Examples are pig iron, wrought iron, cast iron and steel.

Field coils are used in motors. They are called field coils because they consist of a soft iron core, around which is wrapped coils of wire (coils). When electricity is passed through these coils of wire, a magnetic field is produced (field) - hence the term 'field coils'.

Starter motor field coils.


Alternator rotor.

In the context of alternators, field excitation is the act of passing electrical current through the windings on the rotor. The more current we pass through these windings, the stronger the magnet we produce, and the more electricity we generate. In order to regulate the voltage, we switch on and off this field circuit with a voltage regulator.
