Removing:

–	Disconnect battery → Electrical System; Rep. gr.27.

–	Release plug connection on wheel speed sensor and separate plug connector.

–	Unclip wheel speed sensor cable on rear axle and body.

–	Removing the seat bench → Body Work; Rep. gr.72.

–	Removing the entrance plate → Body Work; Rep. gr.68.

–	Fold back the floor covering around the seat bench.

–	Release the rubber grommet -1- and pull the wheel speed sensor cable -2- into the vehicle interior.

–	Separate the ABS speed sensor cable between crimp connection -arrow A- and sheathing -arrow B-.

Installing:

–	Draw in the new wheel speed sensor cable and attach the rubber grommet.

–	Insulate the two cable extremities with a 6...7 mm wire stripper.

–	Twist the two cable extremities.

Note

t	The insulation of the cable extremities must not be twisted.

t	Make sure the correct red crimp connector for 0.5 mm ² is selected.

–	Slide the crimp connector on the cable extremities and crimp together at both sides with the pliers.

Note

t	The crimp connector must be heated from the centre towards the outside until it is fully sealed and the adhesive flows out.

t	Set the hot-air blower to the relevant temperature according to the operating instructions.

t	When heating up the crimp connector, make sure the hot nozzle does not damage any other cables, plastic parts or insulating materials.

–	After pressing on, the crimp connector must be heated with the hot-air blower.

To do so use the hot-air blower from the wiring loom repair kit.

–	If the repair cable was initially insulated, this point must be rewrapped with yellow insulating tape, or if necessary the cable must be attached again with a cable strap.

Further installation occurs in reverse order.
