Removal and installation of components of system of anti-blocking of brakes

Hydraulic modulator

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Remove the tank of hydraulic liquid (see. Head Uniform hydraulic system).
3. Release clamps of fastening of a cover of the hydraulic modulator.

4. Release a clamp and disconnect electroconducting from ECU ABS.

5. Release shtutserny sockets and disconnect from the modulator three hydraulic tubes. Prepare for collecting spilled fuel. At once закупорьте the open ends of tubes and unions for the purpose of minimization of losses of hydraulic liquid and in order to avoid hit in dirt system.
6. Release a collar and disconnect from the modulator a hydraulic hose.

7. Give three fixing nuts and remove the modulator together with the electronic control unit (ECU).
And — Hydraulic tubes
In — the Hydraulic hose
With — Fixing nuts

Installation

Installation is made upside-down. Pay attention to the next moments:
   a) Use for fastening of a hydraulic hose by a new collar;
   b) Do not forget to replace sealing washers of shtutserny sockets at connection of hydraulic tubes;
   c) Installation of the tank of hydraulic liquid make according to the instructions provided in Head Uniform hydraulic system;
   d) In summary do not forget to pump over hydraulic system (see. Pumping of hydraulic system).

Sensors of frequency of rotation of forward wheels

At installation of a hairpin of fastening of wheel sensors it is necessary to grease with special hermetic for fixing of carving connections.

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Prop up protivootkatny boots back wheels, then поддомкратьте a front of the car and establish it on props. Remove the corresponding forward wheel.

3. Screw two fixing bolts and remove the thermofilter from stupichny assembly. Shift aside arms of fastening of a driving cable of the parking brake and sensor electroconducting.



4. Liberate electroconducting from basic arms.
5. Walk on wires from the sensor to the contact socket and disunite the last. Try to remember a route of laying of electroconducting.

6. Turn out a fixing hairpin and remove the wheel sensor.

Installation

 PERFORMANCE ORDER

Installation is made upside-down. Pay attention to the next moments:
   a) Track, that interfaced surfaces of the sensor and stupichny assembly were absolutely pure;

   b) Before a vvorachivaniye grease a carving of a fixing hairpin of the sensor with special hermetic;

   c) Track correctness of laying of electroconducting.

Sensors of frequency of rotation of back wheels

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
2. Cock the parking brake and prop up protivootkatny boots forward wheels. To Poddomkratta a car back also establish it on props. Remove the corresponding back wheel.

3. To Otboltita guard of the longitudinal lever of a suspension bracket.

4. Walk on electroconducting from the sensor to the contact socket and disunite the last.
5. Tie up a piece of a string by the end of a plait of electroconducting of the sensor.
6. Pass electroconducting through space between components of a suspension bracket and untie from it a string which at assembly will be used for dragging of wires on a former route.

7. Turn out a fixing bolt and remove the sensor about the filter.



Installation

Installation is made upside-down. Pay attention to the next moments:
   a) Track correctness of installation of the filter of the sensor;
   b) Before installation make sure of absoluteness of purity of interfaced surfaces of the sensor and the longitudinal lever of a suspension bracket;
   c) For an electroconducting prodevaniye between suspension bracket components on a former route use the string left at removal.

Electronic ABS control unit

Removal

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery. Remove the battery (see. Head engine Electric equipment).
2. In an impellent compartment uncover the assembly block of safety locks/relay.
3. Turn out a bolt and two nuts of fastening of the assembly block.
4. Release clamps and liberate an electroconducting plait from the assembly block. Shift the assembly block aside for the purpose of ensuring access to bolts of fastening of ECU.

5. Release a fixing clamp and disunite the contact socket of electroconducting from above on the control unit.

6. Turn out two bolts of fastening of ECU.

7. Under the control unit wring out a clamp of the electric socket, then pull ECU assembly forward, removing it from a socket block.

Installation

Installation is made upside-down. Try not to injure legs of the contact socket at the ECU installation on the block of the hydraulic modulator.
