What does this fault code mean?
The fault code for direction control of the dampers is set when the control module has detected fault CCM-0017 several times. It shows that the damper motor control is faulty. It is set after CCM-0017, so that is the code to deal with first.
Possible causes
- Faulty damper motor control
What you can do
- 1Deal with fault code CCM-0017 first, since CCM-0018 is set after it
- 2Clear the fault codes and test drive to see whether they return
- 3If the fault returns, have a workshop check the damper motor control
- 4If you have a diagnostic tool, follow the damper position in live data while turning the control and check that it changes smoothly
