ABS control unit (models up to 09.1998 issue.)
1. Remove the lower section of finishing of a ware box.
2. Turn out bolts of fastening, shift the block of management down so that it was possible to separate a socket of electroconducting of the block and remove it.
ABS/ASC T/DSC control unit (models from 09.1998 y.)
After installing a new control unit, it must be programmed, and on models with the DSC system, it is additionally necessary to coordinate the steering wheel position sensor. These procedures require a diagnostic scanner.
1. Disconnect the connector (1), by sliding the latch in the direction (2), and remove the connector by pulling it in the direction (3) (vertically up).
When installing, in order to avoid damage to the contacts, insert the connector plug into the control unit, keeping it strictly perpendicular.
2. Remove the screws (1) and disconnect the electronic control unit (2) from the hydraulic modulator.
Use new screws when installing.
3. Visually check the sealing surface of the hydraulic modulator for damage and clean it.
Do not use sharp-edged tools or aggressive cleaning agents. Check the connector pins for corrosion and damage. If defects in the sealing surface or contacts are found, replace the hydraulic modulator.
4. Carefully fit the control unit onto the hydraulic modulator, avoiding distortion of the excitation coils. The edge of the control unit housing should slide along the protrusion of the hydraulic modulator.
5. Press the control unit against the hydraulic modulator and screw in the fixing bolts (1 and 2), without tightening them until the body of the control unit is evenly adjacent to the hydraulic modulator. Screw in bolts 1 to 6 until the contact surfaces are in contact, and then with the required torque in sequence from 1 to 6.
