 PERFORMANCE ORDER

  1. Disunite the electric socket and compare conductivity on noted (see an illustration below) plugs to specification data. In case of discrepancy try to make adjustment of the sensor switch, then repeat check. If conductivity does not correspond to the table, replace the sensor switch.

The scheme of placement of plugs of the electric socket of the sensor switch of permission of start (above) and the table of connections (below) (only for transmissions of AW-4 of models of 1993 of the issue).

  1. If the sensor switch as it should be, again connect the electric socket and lower the car on the earth. If is not present, - you pass to performing procedures of item 1.

Transmissions 42RE and 42RH/46RH

 PERFORMANCE ORDER

  1. Make sure that the cable of switching of transmission is properly adjusted (Section Check of a State and Adjustment of a Cable of Switching).

The sensor switch will normally not function if adjustment of a cable is broken.

  1. Disunite the electric socket and check a continuity between the central plug of the sensor switch and a case of transmission. The continuity has to take place only in case of installation of transmission in situation "P" or "N".
  1. Check a continuity between the central plug and a case of transmission - it has to take place only at the transmission established in situation "P" or "N" (42RE and 42RH/46RH).
  1. Transfer transmission to position of the reverse gear (Reverse) and check a continuity on external plugs of the sensor switch. The continuity has to take place only in this provision of transmission (Reverse), at the same time there should not be a continuity between external plugs and a case of transmission.
  1. Transfer transmission to situation "Reverse" and check a continuity on external plugs of the sensor switch - it has to take place only in this provision of transmission, however there has to be no continuity between external plugs and a case of transmission.
  1. If the sensor switch as it should be, connect the electric socket and lower the car on the earth. If is not present, - you pass to performing procedures of item 1.

Replacement

AW-4

 PERFORMANCE ORDER

  1. The car also establish to Poddomkratta it on props.
  2. Disunite the electric socket of the sensor switch.
  3. Unbend uvulas of a lock washer and give a nut of fastening of the sensor switch. After a nut remove a lock washer.
  1. Unbend uvulas of a lock washer, then remove a nut of fastening of the sensor switch of permission of start and its lock washer (only AW-4 of models of 1993 of the issue).
  1. Give an adjusting bolt of the sensor switch.
  2. Remove the sensor switch from an axis.
  3. Disconnect a rod of draft of switching from the switching lever on the left side of transmission.
  4. Turn the lever handle against the stop back, then translate it through two fixed situation forward. Now the lever will fall into a state "N".
  5. Install the sensor switch on an axis of the manual valve and by hand tighten an adjusting bolt. Do not tighten a bolt finally yet.
  6. Establish a lock washer on an axis of the manual valve and fix the sensor switch by a nut. Tighten a nut with the required effort, however do not bend uvulas of a lock washer so far.
  7. Make sure that transmission is in situation "N" and turn the sensor switch until standard line of neutral provision of transmission on its case is not combined with a vertical flute in an axis of the manual valve.
  1. At the transmission established in situation "N" rotate the sensor switch of permission of start until standard line of neutral provision of transmission on the case of the sensor switch is not combined with a vertical flute in an axis of the manual valve (only AW-4 of models of 1993 of the issue).
  1. Tighten an adjusting bolt with the required effort and bend uvulas of a lock washer, законтрив a fixing nut of the sensor switch.
  2. Connect the electric socket and draft of switching, lower the car on the earth and check functioning of the sensor switch, having convinced that start of a starter is possible only provisions of transmission "Р" and "N". Before check do not forget to cock the parking brake reliably.
