If start of the engine is carried out in any, excellent from stipulated, position of the lever of the selector, it is necessary to make sensor switch adjustment. Besides, the sensor switch of permission of start acts as the information sensor, informing the electronic control unit transmission inclusion of the provisions "R" and "N" AT.

CHECK

 PERFORMANCE ORDER

1. Disunite contact sockets of the sensor switch of permission of starts/fires of a backing and start performance of checks:

a) At the lever of the selector transferred to the position "R" conductivity between plugs 1 and 2 and 3 and 4 of sockets should take place;
b) Conductivity should be present at the position "R" of the lever between plugs 3 and 5;
c) In the situation "N" - between plugs 1 and 2 and 3 and 6;
d) In situation "D" - between plugs 3 and 7;
e) In situation "2" - between plugs 3 and 8;
f) In situation "1" - between plugs 3 and 9.

2. At negative results described above check disconnect a driving cable of management of gear shifting from the manual lever of switching, then repeat a checking procedure:

a) If this time the sensor switch starts to work regularly, restore initial connection of a cable, adjust it and repeat check;
b) If correctness of distribution of provodimost between plugs of sockets still remains broken, remove the sensor switch from transmission and make check it on a workbench;
c) If the sensor switch works at a workbench regularly, establish it on a place and adjust (see below);
d) The faulty sensor switch is subject to replacement.

ADJUSTMENT

 PERFORMANCE ORDER

Weaken screws of fastening of the sensor switch, transfer the manual lever to the situation "N" and pass a core in diameter of 3.9 mm through adjusting openings in the lever and the sensor switch.

2. Repeat check of distribution of provodimost (see above). At negative results of check replace the sensor switch.

REPLACEMENT

 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.

 If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for audiosystem input in action!

2. Switch transmission in the situation "N".
3. Disconnect from the sensor switch electroconducting.
4. Turn out fixing screws and remove the sensor switch.
5. At installation the final tightening of fixture is made after performance of adjustment of the sensor switch.
