Fault diagnosis 17
General description
This chapter has information that will assist with the diagnosis of mechanical faults and electronic faults on the
engine, and its management system.
Two types of faults are found by the engine control module (ECM) and retained in its memory, they are active
faults and inactive faults. Active faults and inactive faults are shown on the diagnostic tool as “ACTIVE
CODES” and “INACTIVE CODES”.
l
An active fault is one that was found by the engine control module and has not been repaired. When an
active fault has been repaired, it becomes an inactive fault after 15 seconds.
l
An inactive fault is one that was an active fault at some time, but is not present now. This could be because
it was repaired, or it is an intermittent fault.
Some applications are fitted with a self-test system, which can be used to check for active faults and inactive
faults. It will also check all outputs for open circuit.
A special diagnostic tool is necessary to operate the full range of diagnostic tests on the engine management
system.
The two diagnostic tools available are: the Pro-link 9000 hand held tool, and a PC based system.
The following procedures are carried out using the Pro-link 9000 hand held tool.
