Before Changing A Control Module
Before Changing A Control Module
It is our experience that the majority of control modules returned for repair or replacement under warranty are in perfect working order. In these cases,
fitting a new control module has obviously not cured the fault. Therefore, go through all the following points carefully before changing the control
module:
1. Check the latest edition of TIS2000 to see whether the problem can be solved with a control module software update (for control modules that can
be reprogrammed).
Important: Avoid SPS programming unless it is absolutely necessary. It is extremely important to follow the instructions for SPS programming
to avoid damaging the control module.
