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 subject to adjustment applied on models of 1993 вып. it is fixed on an arm by means of a clip; the sensor switch with the automatic adjustment, established on model since 1994 вып. fastens in an arm by means of the built-in clamp.

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

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

Check

Models of 1993 вып.

 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 pedal, check a condition of a safety lock and lamps of signals (Head System of onboard electric equipment), then again check sensor switch functioning.
  3. If after introduction of corrections stoplights on the former do not work, try to make sensor switch adjustment. Again repeat check.
  4. If adjustment of the sensor switch did not help, make sure available on plugs of the switch of a food (see electric circuits at the end of Head System of onboard electric equipment).
  5. If a food is present, whether check it takes a place on plugs of feeding conducting of lamps of stoplights.
  6. The faulty switch replace. If to achieve satisfactory operation of stoplights it is not possible despite 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 вып.

 PERFORMANCE ORDER

  1. First of all carry out all external checks described in the previous subsection (a safety lock, lamps, a food on the switch, tension between the switch and lamps, etc.).
  2. If to eliminate refusal it was not possible, remove the sensor switch, disunite its electric socket, then establish the switch on a 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:
    • For full length take a plunzher of the sensor switch.
    • 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 break or short circuit takes place).

Scheme of identification of plugs of the socket of the sensor switch (model 1993 and 1994 of вып.)

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 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 plunzher 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 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 bottom panel of an upholstery under the dashboard (Head the Body).

Models of 1993 вып.

 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 planted it in the holder so that the plunzher rested against a brake pedal.
  4. Connect the electric socket.
  5. Make sensor switch adjustment.

Models 1994 and 1995 of вып.

 PERFORMANCE ORDER

  1. Against the stop squeeze out a brake pedal.
  2. Turn the sensor switch approximately on 30 ° counter-clockwise 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. For full length take a plunzher from the sensor switch.
  5. Connect the electric socket.
  6. Squeeze out a pedal against the stop and hold her 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 plunzher of the sensor switch to occupy the correct working situation at a vtalkivaniye it a pedal in the switch case. During automatic adjustment the sensor switch should publish clicks.

All models

 PERFORMANCE ORDER

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

Adjustment (only for models of 1993 вып.)

 PERFORMANCE ORDER

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