Diagnostic Fault Information

Circuit Description

The seat memory control module monitors the position of the seat motors by using hall effect position sensors which are an internal part of each

motor. The module supplies each sensor with a 12 V reference circuit and a low side signal circuit. During seat motor operation, the hall effect

position sensor provides a determined number of pulse signals for every revolution of the motor shaft. The scan tool displays these pulse signals as

counts that range from 0 - 65,535. The module counts the feedback pulses from each sensor to determine seat position and end of travel limits for

each of the seat motors. High scan tool count values indicate forward or upward seat positions while low count values indicate rearward or

downward seat positions.
