Test I: The Memory Seat Does Not Operate Correctly - Does Not Operate Using the Memory Set Switch, Early Production

PINPOINT TEST I: THE MEMORY SEAT DOES NOT OPERATE CORRECTLY - DOES NOT OPERATE USING THE MEMORY SET SWITCH, EARLY PRODUCTION

Normal Operation
The driver seat control switch is supplied battery voltage on circuit SBP12 (GN/RD) and is supplied ground on circuit GD179 (BK/VT). When pressed, the seat control switch supplies the voltage and ground to the applicable driver seat module (DSM) inputs. The DSM then supplies voltage and ground to the appropriate power seat track motor based on the inputs received from the seat control switch. When pressed in the opposite direction, the seat control switch reverses the polarity to the DSM inputs, and the DSM likewise reverses polarity of the appropriate power seat track motor circuits causing the seat to move in the opposite direction. There are 3 power seat track motors that combine to move the seat horizontally (forward/rearward) and vertically (front up/down and rear up/down). Battery voltage is supplied to DSM circuit SBB45 (GY/RD) and SBP12 (GN/RD). Ground is supplied to DSM circuits GD179 (BK/VT) and GD133 (BK). Each motor in the memory power seat track contains a Hall-effect position sensor. The DSM supplies a signal feed circuit to each position sensor and a shared reference signal return circuit. Each position sensor sends a signal voltage back to the DSM used to monitor the position of the power seat and seat backrest. The DSM uses this information to return the seat to a stored pre-programmed position when pressing the memory SET switch or a remote entry transmitter. For information on programming memory positions or recalling a stored memory position, refer to Memory Position Programming. Programming and Relearning

The following pinpoint test diagnoses a memory seat that does not operate correctly using the memory set switch or operates in one-second intervals. If the memory seat does not move in all directions using the seat control switch, GO to Pinpoint Test H. Test H: The Memory Seat Is Inoperative Does Not Operate Correctly - Does Not Operate Horizontally/Vertically, Early Production
