Refitting

- Deactivate the self-levelling suspension control system by simultaneously pressing the two adjustment buttons in the dashboard (for at least 5 secs.) and the LEDs in the buttons should both come on constantly.

- Position the vehicle on the lift.

- Turn the ignition key to the OFF position.

- Remove the battery cover.

Op. 5530B54

- Disconnect the negative battery terminal.

- Remove the control unit / compressor module guard.

1. Disconnect the electrical connectors (1a) and (1b) from the control unit using the anti-release safety slide (1c).

1. Slightly undo the connector (1a) for the (black) compressed air pipe (1b) to the accumulation reservoir until the pressure in the circuit is completely discharged then undo the connector completely.

2. Undo the connector (2a) for the red compressed air supply pipe (2b) to the right spring.

3. Undo the connector (3a) for the green compressed air supply pipe (3b) to the left spring.

1. Disconnect the compressor air inlet pipe (1a) using the rapid connector (1b).

1. Undo the nuts (1a) securing the mounting bracket (1b) for the control unit/compressor module and remove the module (1c) complete with bracket.

1. Remove the tapered inner seal (1b) from the air pipes (1a) disconnected previously from the control unit/compressor module and then release the rapid connector (1c).

The connector is ruined during the removal so it cannot be kept but must be replaced with a new one.

Removing

- Check that the control unit/compressor module is not damaged otherwise it must be replaced.

1. Tighten new rapid connectors (1a) with tapered inner seals (1b) on the control unit/compressor module.

During this operation take great care to fit the connector properly on the thread to prevent possible damage to the module.

1. Place the control unit/compressor module (1a) in position complete with mounting bracket (1b) then secure it tightening the nuts (1c) to the recommended torque.

1. Connect the compressor air inlet pipe (1a) using the rapid connector (1b).

1. There are two reference lines (1b) and (1c) at the ends of the air pipes (1a). Fit the air pipes about 20 mm into the rapid connectors for the control unit/compressor module or as far as necessary to leave only one line (1c) showing following the instructions for the colours given on the label (1e) on the module.

Once the pipe is fitted it cannot be removed without replacing the actual connector.

1. Connect the electrical connectors (1a) and (1b) to the control unit and fit the anti-release safety slide (1c).

- Position the control unit / compressor module guard.
