Check and adjustment of control system components AT
general information AT control system can be divided into three subgroups: the components that make up TCM input information (including ECM); Strictly control module (TCM) and actuators. Functional diagram of the control system of the AT  Identification card connector terminals for petrol models of SCI   Checks TCM Switch on the ignition - the engine does not start. Uncover pin TCM (driver's side) and check the distribution of voltage at its terminals, - the measurement is made between the respective terminal and ground If necessary, replace the control module.

Identification card connector terminals TCM diesel models  Solenoid valves For example, petrol models | - Disconnect the electrical wiring from the TCM and measure resistance between plugs ?��?�� 8, 7 and 22 of its connector, - the required value is 11 ÷ 15 ohms at 20 ?� C.
- Feeding on plugs ?��?�� 7, 8 and 22 voltage () battery, at the hearing make sure of serviceability of operation of the solenoid valves (clicks should be heard in the sump AT).

The gauge-switch of the selector lever position (PNP) Checks PNP plays the role of gauges-switches permit the launch and activation of lights reverse. | - Make sure of serviceability of activation of a starter in the "P" and ?�N?� of the selector lever in the other positions of the lever activating the starter should not be possible.
- Make sure of serviceability lights activated when reverse gear lever is in position ?�R?� (ignition must be included).
- Disconnect from the gauge-switch wiring and check the distribution of conductivity between terminals connector in different positions of the selector lever. If necessary, make the appropriate adjustments.
