The self-test system
How to check for faults codes
Operation 17-1
The self-test system should be fitted to every application, it can be used to find faults in the engine
management system.
The self-test system usually consists of a button, an orange lamp and a red lamp.
1 Set the start switch to the ‘ON’ position, but do not start the engine.
2 Press the self-test button once.
Notes:
l
If there are no ‘ACTIVE CODES’ retained in the memory of the ECM, the red lamp will flash once, then the
orange lamp will flash three times. For further information refer to "Flash codes" on page 246.
l
If there are any ‘ACTIVE CODES’ retained in the memory of the ECM, the red lamp will flash once. Then
the orange lamp will flash a code. If there is more than one code retained, there will be a short delay
between codes.
l
When all of the retained ‘ACTIVE CODES’ have been shown, the red lamp will flash twice. Then, if there
are any ‘INACTIVE CODES’ retained, the orange lamp will flash a code. If there is more than one code
retained, there will be a short delay or the red lamp will flash once, between codes.
l
When the test is complete, the red lamp will flash three times.
3 Make a note of any codes that are shown.
4 Set the start switch to the ‘OFF’ position.
How to test for an open circuit
Operation 17-2
This test will check the outputs for open circuit faults.
Note: Before this test is done, check for faults codes, see Operation 17-1. This will assist with fault diagnosis.
1 Set the start switch to the ‘OFF’ position.
2 Press and hold the self-test button. Set the start switch to the ‘ON’ position, but do not start the engine.
3 Release the self-test button.
4 Make a note of any codes that are shown.
Notes:
l
If there are any ‘ACTIVE CODES’ retained in the memory of the ECM, the red lamp will flash once. Then
the orange lamp will flash a code. If there is more than one code retained, there will be a short delay
between codes.

retained, there will be a short delay or the red lamp will flash once, between codes.
l
When the test is complete, the red lamp will flash three times.
5 Set the start switch to the ‘OFF’ position.
