The memory seat module (MSM) is supplied battery positive voltage (B+) at connector C4 cavity B (RED) from the seats circuit breaker in the left underhood fuse block. This battery positive voltage (B+) supply powers the seat motors.

CONDITIONS FOR SETTING THE DTC
The dirty battery positive voltage (B+) falls out of the range of 9.0-15.5 volts.

CONDITIONS FOR CLEARING THE DTC
The dirty battery positive voltage (B+) is within a valid operating range during the last monitoring cycle.

DIAGNOSTIC AIDS
1. Test the battery for proper voltage.
2. If the battery voltage is OK, test for an open in CKT 742 (RED) between S311 and the memory seat module (MSM).
