Seat Memory Beeps or Fails to Recall

SYMPTOMS

When a seat position is recalled:

1. The seat memory beeps twenty times.

2. The seat does not move, or moves to the wrong position.

PROBABLE CAUSE

The number of pulses required to recall the seat position exceeded the control unit's memory capacity, causing it to lose the memorized position.
