Press switch (1) on the lower left side of the switch panel until the service codes are displayed. The service code will be shown in display window (2) when a diagnostic code has been detected.

There are three different types of service codes. The codes are identified on the following tables:

The Component Identifier (CID) is a diagnostic code which indicates the component or the system that is faulty.

Table 3
Failure Mode Identifier (FMI)
Code Number	Description
0	The data is valid but the operational range is above normal.
1	The data is valid but the operational range is below normal.
2	The data is erratic, intermittent, or incorrect.
3	The voltage is above normal or the circuit is shorted high.
4	The voltage is below normal or the circuit is shorted low.
5	The current is below normal or there is an open circuit.
6	The current is above normal or there is a grounded circuit.
7	A mechanical system is not responding properly.
8	The frequency, the pulse width, or the period is abnormal.
9	The update is abnormal.
10	The rate of change is abnormal.
11	The failure mode is not identifiable.
12	A device or a component is faulty.
13	Calibration is needed.
