Seat calibration, function - GF91.29-P-3005S

Models 215, 220 

Function requirements:

• Voltage not too high or too low
• Seat adjustment switch is not pressed.

Through normalization in the left front seat adjustment control module with memory (N32/1)/right front seat adjustment control module with memory (N32/2) the counter counts of the position recognitions of the adjustment motors are linked to the actual positions.

The normalization is a prerequisite for easy entry (model 215 only) and the Ergo function up to 31.5.01.

Performing normalization 

Separate normalization is required for each adjustment motor. Normalization occurs by approaching the respective mechanical stop. Actuation must be carried out in this position for a further 250 ms at least.

Once normalization has been carried out, the control module must be still supplied with voltage for at least 5 seconds in order to ensure a complete and faultless storage in the nonvolatile memory (EEPROM).

The mechanical stop relevant to the respective normalization:
