Replacing the Control Module
Replace the located and damaged Damper motor module (DMM). After replacement, check that the customer symptom no longer remains.
If customer symptoms remain, check that the Climate control module (CCM) has the latest software. Check this by purchasing an upgrade for the Climate control module (CCM) and downloading it to the control module.
NOTE:
After downloading new software, all parameters are reset and further fault tracing becomes harder.
After downloading, check whether the customer symptoms remains.
The fault must now be detected and remedied. If this is not the case, the fault-tracing has failed. Exit symptom fault-tracing or try again.
