Memory Positioning Switch: Description and Operation

Memory Buttons










The switch unit for memory retrieval and programming contains four buttons. Three memory buttons, "1", "2" and "3" and the memory store button "M".

Memory Retrieval

The seat position is programmed/stored as follows:
1. Set the seat to the required position using the adjustment switch.
2. Program the settings by simultaneously pressing the "M" button and one of the memory buttons 1, 2 or 3.
3. When the settings have been stored, SID gives an acoustic signal.

When settings are being stored in memory, the control module reads all Hall sensors and stores their values in an internal seat memory. The seat memory is non-volatile and retains the data even when the control module power is turned off.

Recalling memory setting

To activate the memory function, hold down the desired memory button until the seat has assumed the stored memory settings.

The control module reads all Hall sensors and controls the motors until the seat position corresponds to that stored in the seat memory or until the memory button is released. If the seat has not assumed the correct position within 1 minute, the control module interrupts the power supply to the motors.

If the control module detects a fault on any Hall sensors, the motor concerned will be stopped.

Diagnostics

If the memory buttons do not function correctly, their positions can be read with the diagnostic tool. No diagnostic trouble codes are generated.
