Removal and installation of the ABS and TCS components

Hydraulic modulator and block of electronic control (ECU)

Removal

 PERFORMANCE ORDER

  1. Remove the storage battery (see. Head engine Electric equipment).
  2. Disconnect two multicontact sockets from an arm of the assembly block of the relay.
  3. Uncover the assembly block, liberate the last from a basic arm and take him aside.
  4. Liberate from an arm electroconducting plaits.
  5. Give three fixing nuts and remove a basic arm of the assembly block of the relay.
  6. Remove the holder from brake tubes.
  7. Uncover the GTTs tank and pump out its all liquid by means of a syringe or a rubber pear.
  8. Mark brake tubes, release nuts of shtutserny sockets and disconnect tubes from the modulator, - for the purpose of rounding off prevention шлицов hardly tightened nuts use a cap natural a cutting head. Prepare for collecting spilled liquid, - enclose under shtutserny sockets connection rags. Also disconnect brake tubes from GTTs (see. Removal and installation of the main brake cylinder). At once закупорьте or stick with an opening adhesive tape in the modulator, the cylinder and tubes for the purpose of hit prevention in dirt system.
  1. Having released a clamp, disunite the special multicontact socket in the top part of the hydromodulator.
  1. Give fixing bolts / nuts, remove the modulator and the ABS control unit from a basic arm and take them from an impellent compartment, - try not to allow hits of brake liquid on the painted body surfaces.

For the purpose of minimization of losses of liquid do not overturn the modulator in the course of dismantle.

Installation

Installation is made as it should be, the return to an order of dismantle of components.

In summary pump over brake system (see. Pumping of brake system).

Wheel sensors

Replacement

Sensors are built in naves of wheels and in case of failure are subject to replacement complete with them (see. Head Suspension bracket and steering).

TCS switch

Removal

 PERFORMANCE ORDER

  1. Having accurately hooked a screw-driver, remove the sensor from the dashboard, - in order to avoid damage of the panel enclose under a screw-driver a piece of a cardboard or rags.

Installation

Installation is made as it should be, the return to an order of dismantle of components.

ABS control unit

Removal

 PERFORMANCE ORDER

  1. Remove the hydromodulator with collecting by the electronic ABS control unit (ECU) (see above).
  2. Disconnect electroconducting, in turn out fixing bolts and remove ECU ABS from the hydromodulator, - try not to damage the holder of the coil.
  3. Remove established between the holder of the coil and the control unit a sealing element.

Installation

 PERFORMANCE ORDER

  1. Lay a new sealing element, establish ECU on assembly of the hydromodulator and in some stages tighten new fixing bolts with demanded effort (see. The specification), - do not allow ECU deformation at installation it on the modulator. If bolts are wrapped hardly, it is necessary to replace the block assembled.

If at removal between the hydromodulator and the control unit the spring plate was established, to establish it into place does not follow.

  1. Further installation is made as it should be, the return to an order of dismantle of components.
