The control module has registered an internal fault. Try a new control module.

NOTE:

New control modules are delivered with pre-programmed values from the factory. The control module must be programmed with the relevant data for the market, body type etc. in order for it to function correctly after replacement.

The programmed values must therefore be read from the existing control module and noted.
