Memory Buttons

Memory Buttons

The switch for the memory retrieval and programming contains four buttons. Three memory buttons, "1," "2" and "3," and the programming button "M."
The memory buttons and programming button are common to two Systems: PSM and PMM. The PMM system stores the door mirror settings.

Programming
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 programming settings, 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.

Memory Retrieval
To activate the memory function, hold down the required 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 is stopped.

Diagnostics
If the memory button function is not correct, the memory button position can be read using the diagnostic tool. No diagnostic trouble codes are generated.
