Ripple Count Recognition
When the seat is installed and the battery is connected, the ripple counter uses the initial position of the motors as the "Zero Position". Any movement from this point is counted as "+" or"-" pulses as the motors move in either direction.
The pulse position of the motors is stored in the seat module, in an EEPROM (of the PM-SM), before the ZKE goes into its "Sleep Mode".
This prevents the position recognition from being lost. If the battery is disconnected before the 16 minute sleep mode activation, the memory positions of the seat will be lost and reprogramming will be required.
