GROUP ‘A’ FAULT CODES
If a fault is detected by the system, a number will appear
under one or more of the four group headings A through
D. This number will correspond to one or more fault
diagnostic numbers. The meaning of these numbers can
be determined by looking at the appropriate code in the
fault interpretation table.
Group A fault codes relate to analog sensors. Each
sensor is allocated a number and this number is also the
number of the channel to which it is connected in the
system.

Each sensor is allocated a FAULT CODE and this is the
number that appears under the group heading in the fault
code display.

When there are no faults detected in the system, ‘000’
will appear under all group headings indicating that there
are no detected faults in the system. When there are
faults in only one sensor, the code will be one of the
codes listed above. When there are faults in more than
one sensor, the codes indicated will be the sum of the
fault codes.
