Pinpoint Test As : DTC B1317: Notes

Refer to Memory Seats , for schematic and connector information.

Normal Operation 

The Driver Seat Module (DSM) continuously monitors the input voltage for correct operation. If the DSM detects input voltage below 11 volts, it stores DTC B1318 in memory. If the DSM detects input voltage above 15 volts, it stores DTC B1317 in memory. If DTC B1317 or B1318 is set, the DSM disables the memory system outputs for the driver seat memory operation.

• DTC B1317 (Battery Voltage High) - a continuous memory DTC that sets when the DSM detects battery voltage above 15 volts.

This pinpoint test is intended to diagnose the following: 

• Charging system concern
• DSM
