Pinpoint Test Ca : DTC B1318: Notes

Pinpoint Test CA: DTC B1318 

Refer to Wiring Diagrams 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) - This DTC sets if the DSM detects voltage below 11 volts.

This pinpoint test is intended to diagnose the following: 

• Wiring, terminals or connectors
• High circuit resistance
• DSM
