Check operation, removal, installation and adjustment of the gauge-switch of stoplights

1. Make fires stoplights at squeezing the brake pedal.
2. If the brake lights do not light up when the squeezing of a pedal, check the fuse and signal lamps (Head System of an onboard electric equipment), then re-check the functioning of the gauge-switch.
3. If after patching brake lights still do not work, try to make adjustment of the gauge-switch. Again, repeat the test.
4. If the adjustment of the gauge-switch does not work, make sure there is a power switch terminals (see. Wiring diagrams at the end of the Head of System of an onboard electric equipment).
5. If power is present, check whether it has a place at the terminals of the mains wiring lamps of stoplights.
6. Replace the faulty switch. If a satisfactory response stoplights fails despite the fact that the sensor switch in order, try to find a short circuit or open circuit in the wiring between the switch and stop lamp.

1. First of all spend all external checks described in the previous section (fuses, lamps, power on the switch, the voltage between the switch and a lamp, etc.).
2. If you are still unable to failure, remove the gauge-switch of his disunite an electric socket, then set the switch in place (see. Below) and using an ohmmeter or continuity tester, check the continuity between terminals 5 and 6 of the connector, as follows:
   • At full length, remove the plug gauge-switch.
   • Connect the ohmmeter between said terminal and read the readings.
   • If there is no continuity, proceed to the next check. If there is, - replace the gauge-switch (in which there is a break or short circuit).

Driving identification terminal connector gauge-switch (models 1993 and 1994 issue.)

1 - Terminals 1 and 2 - circuit brake sensor 2 - Terminals 5 and 6 - the contour of stoplights 3 - Terminals 3 and 4 - loop speed sensor (VSS)

3. Using an ohmmeter or continuity tester, check the continuity between terminals 1 and 2, then 3 and 4:
   • Squeeze the plunger all the way to the sensor switch.
   • Connect the ohmmeter between terminals 1 and 2 of the connector and take a reading device.
   • If continuity is present, the circuit breaker is in order. If not - replace it (it holds an open or short circuit).
   • Repeat the test for the terminals 3 and 4.

1. Disconnect the negative wire from the battery.
2. Remove the lid and lower steering column trim panel under the dashboard (Section Body).

1. Disconnect an electric socket of the gauge-switch.
2. Remove the gauge-switch of the holder or, shaking up and down, pull back out of the holder.
3. Screw the new sensor switch, set him completely in the holder so that the plunger rested in the brake pedal.
4. Connect the electrical connector.
5. Make adjustment of the gauge-switch.

1. Until it stops depress the brake pedal.
2. Turn the sensor switch by about 30 ?� counterclockwise to release the latch, then pulling back, remove the switch from the bracket.
3. Disconnect the electrical connector and remove the sensor switch.
4. At full length, remove the plug from the gauge-switch.
5. Connect the electrical connector.
6. Depress the pedal until it stops and hold it in this position.
7. Align the stop tab gauge-switch of a return slot in the bracket and insert the switch into the bracket by turning the lock 30 ?� clockwise.
8. Release the brake pedal and pull it back completely. This will allow the gauge-switch plunger into the correct working position when pushed into the body of his pedal switch. In the course of automatic adjustment of the gauge-switch shall make the clicks.

1. Replace the trim panel and the cover of the steering column (head body).
2. Connect a wire to the negative terminal of the battery
3. Try the operation of the gauge-switch.

1. Manually move the brake pedal forward and check the functioning of the gauge-switch plunger (useful would use a flashlight and a small mirror). The plunger should be in the fully extended position when the free travel will be selected and will start braking the vehicle. The gap between the head and foot of the plunger at this point should be between 1.6 to 3.2 mm.
2. If the gap between the plunger and the gauge-switch pedal normally and brake lights are included properly, adjustment is not required.
3. If the plunger switch is not completely pulled out of the body, ie, the gap between the plunger and foot below normal, adjust, for which:
   • Grasp the brake pedal and pull it back until it stops.
   • The pedal should not touch the cylinder switch, push it back in the clamp and lock in the correct position.
   • Again measure the gap between the plunger and the pedal. If necessary, repeat the procedure
4. Try the operation of the gauge-switch.
