Functioning check, removal, installation and adjustment of the sensor switch of stoplights

The sensor switch of stoplights is fixed on a flange on a basic arm of a pedal of a brake. The sensor switch which is subject to adjustment used on models of 1993 of the issue is fixed on an arm by means of a clip; the sensor switch with automatic adjustment installed on model since 1994 to the issue fastens in an arm by means of the built-in clamp.

Details of installation of the sensor switch of stoplights of models of 1993 of the issue.

Assembly the sensor switch of stoplights (model since 1994 of the issue).

Check

Models of 1993 of the issue.

 PERFORMANCE ORDER

  1. Make sure of operation of stoplights when squeezing a pedal of a brake.
  2. If stoplights do not light up when squeezing a pedal, check a condition of a safety lock and lamps of signals (The head Sistema of onboard electric equipment), then again check functioning of the sensor switch.
  3. If after introduction of corrections stoplights still do not work, try to make adjustment of the sensor switch. Again repeat check.
  4. If adjustment of the sensor switch did not help, make sure available on food switch plugs (see electric circuits at the end of the Head Sistem of onboard electric equipment).
  5. If food is present, check whether it takes place on plugs of the feeding conducting of lamps of stoplights.
  6. Replace the faulty switch. If it is not possible to achieve satisfactory operation of stoplights in spite of the fact that the sensor switch as it should be, try to find short circuit or break in conducting between the switch and lamps of stoplights.

Models since 1994 of the issue.

 PERFORMANCE ORDER

  1. First of all carry out all external inspections described in the previous subsection (a safety lock, lamps, food on the switch, tension between the switch and lamps, etc.).
  2. If it was not succeeded to eliminate refusal, remove the sensor switch, disunite its electric socket, then install the switch into place (see below) and by means of an ohmmeter or a tester of breaks check a continuity between socket plugs 5 and 6 for what:
    • At full length take a sensor switch plunger.
    • Connect ohmmeter wires between the mentioned plugs and consider instrument readings.
    • If the continuity is absent, pass to the following check. If takes place, - replace the sensor switch (in it the break or short circuit takes place).

Scheme of identification of plugs of the socket of the sensor switch (models 1993 and 1994 of of the issue)

1 — Plugs 1 and 2 - a contour of the brake sensor
2 — Plugs 5 and 6 - a contour of stoplights
3 — Plugs 3 and 4 - a contour of the sensor of the speed (VSS)

  1. By means of an ohmmeter or a tester of breaks check a continuity between plugs 1 and 2, then 3 and 4:
    • Against the stop press a plunger in the sensor switch.
    • Connect ohmmeter wires between plugs 1 and 2 of the socket and consider instrument readings.
    • If the continuity is present, the switch as it should be. If is not present, - replace it (in it the break or short circuit takes place).
    • Repeat check for plugs 3 and 4.

Replacement

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  2. Uncover a steering column and the lower panel of an upholstery under the dashboard (Head Kuzov).

Models of 1993 of the issue.

 PERFORMANCE ORDER

  1. Disunite the electric socket of the sensor switch.
  2. Turn out the sensor switch from the holder or, having shaken up-down, extend from the holder back.
  3. Screw the new sensor switch, having completely put it in the holder so that the plunger rested against a brake pedal.
  4. Connect the electric socket.
  5. Make adjustment of the sensor switch.

Models 1994 and 1995 of of the issue.

 PERFORMANCE ORDER

  1. Against the stop squeeze out a brake pedal.
  2. Turn the sensor switch approximately on 30 ° counterclockwise to a clamp otpuskaniye, then, having pulled back, take the switch from an arm.
  3. Disunite the electric socket and remove the sensor switch.
  4. At full length take a plunger from the sensor switch.
  5. Connect the electric socket.
  6. Squeeze out a pedal against the stop and hold it in this situation.
  7. Combine a lock uvula of the sensor switch with a reciprocal groove in an arm and insert the switch into an arm, having turned for fixing on 30 ° clockwise.
  8. Release a pedal of a brake and completely delay it back. It will allow a plunger of the sensor switch to reach the correct working position at pushing-in by its pedal in the switch case. During automatic adjustment the sensor switch has to publish clicks.

All models

 PERFORMANCE ORDER

  1. Install into place the panel of an upholstery and a cover of a steering column (Head Kuzov).
  2. Connect a wire to the negative plug of the battery
  3. Test functioning of the sensor switch.

Adjustment (only for models of 1993 of the issue)

 PERFORMANCE ORDER

  1. Manually translate a brake pedal forward and check functioning of a plunger of the sensor switch (useful will be an application of a pocket small lamp and small pocket mirror). The plunger has to remain in completely extended situation when the free wheeling of a pedal is braking of the car is chosen and will begin. The gap between a head of a plunger and a pedal in this point has to make from 1,6 to 3,2 mm.
  2. If the gap between a plunger of the sensor switch and a pedal is normal, and stoplights join regularly, adjustment is not required.
  3. If the plunger of the switch is not completely put forward from the case, i.e. the gap between a plunger and a pedal is lower than norm, make adjustment for what:
    • Grasp a pedal of a brake and delay it back against the stop.
    • The pedal has to concern the switch cylinder, push it back in a clip and record in the correct situation.
    • Again measure a gap between a plunger and a pedal. In case of need repeat the procedure
  4. Test functioning of the sensor switch.
