Before changing a control module
|
It is our experience that the majority of electronic control modules returned to us for repair or replacement under warranty are in perfect working order. In these cases, fitting a new electronic control module has obviously not cured the fault. Therefore, go through all the following points carefully before changing the electronic control module:
|
1.
|
Check all grounding points and the power supply to the electronic control module.
|
|
2.
|
Using the diagnostic instrument, check that all readouts are plausible.
|
|
3.
|
Using the diagnostic instrument, check that all activation commands produce the correct results.
|
|
4.
|
If the fault persists, the electronic control module must be replaced.
|
|
5.
|
When handling the electronic control module, it is important to ground yourself by touching the engine for example. Avoid touching the pins of the electronic control module.
