CIRCUIT
| 25, 26, 27, 28 | The potentiometers of the motors are monitored as follows: |
· Potentiometer voltage (contact line) greater than approx. 4.7 V
(circuit interruption or short circuit to voltage)
· Potentiometer voltage (contact line) less than approx. 0.1 V
(short circuit to ground)
· The voltages of the contact lines are read and evaluated every 20 ms
Effects:
· The automatic adjuster for the motor with the faulty potentiometer is blocked
· If the fault occurs in the potentiometers for front and / or rear seat height, both corresponding motors are blocked for manual adjustment as well
· If the fault occurs in the vertical potentiometer of the right outside mirror, the parking aid mode is blocked
· The final stop of the affected motor is not monitored, i. e. the affected motor is not switched off when the programmed final stop is reached
· The position of the affected motor is not stored
The adjusting speed of the motors is monitored as follows:
· The adjusting speed is monitored to protect the motor against overload, blocking or wrong operating direction;
The direction - dependent change in the potentiometer voltage of each running motor is measured and evaluated per second
· The above test is performed during adjustment of a motor
Effect:
The affected motor is blocked for the current adjustment cycle (manual or automatic adjustment) until the relevant button is released again
