What does this fault code mean?
Although the code is named clutch actuator out of range, it applies when the clutch control for the electric rear axle (DCC) performs routines that the electric rear axle drive control module (IEM) has not requested. The clutch in the rear axle is a dog clutch that can mechanically disconnect the electric rear axle. The causes are an internal fault in the DCC, a damaged DCC, or a software fault in the IEM. Electric propulsion is then not possible.
Possible causes
- Internal fault in the clutch control for the electric rear axle (DCC)
- The clutch control for the electric rear axle (DCC) is damaged
- Software fault in the electric rear axle drive control module (IEM)
What you can do
- 1Have a workshop check the clutch control for the electric rear axle (DCC) and download new software to the IEM if needed. High voltage systems may only be handled by qualified personnel
- 2If you have a diagnostic tool: read the fault codes after the car has been started and see whether the code is set again
- 3Do not carry out any work on the clutch control or the electric rear axle yourself
- 4After the repair, check that the code is not stored again
