Removing - refitting

Remove the control unit as follows:

• disconnect both connectors in two stages:
  A) turn the metal hook up to release the connection;
  B) pull away the connection;
• unscrew the control unit retaining bolts and remove.

Proceed as follows to refit the connector:

• move the connector into contact with the control unit;
• turn the metal hook until completely closed.
