WARNING: This page is about a different car, the 2016 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
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 B1318 (Battery Voltage Low) - a continuous memory DTC that sets when the DSM detects battery voltage below 10 volts.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
