Circuit Description

WARNING: This page is about a different car, the 2000 Chevrolet Corvette. However, it is still accessible from the selected car via links, so may be relevant.

Seat Control Module (SCM) has 2 main power feeds (high and low) and one main ground. Low power feed (battery 1) is used to provide power for SCM logic and internal driver operation. High power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motor, lights, etc.). For most functions, SCM will operate properly when vehicle system voltage is 9.0-16.0 volts. SCM also monitors voltage level at battery 1 and battery 2 circuits, and can determine if voltage level received is out of range.

DTC B0846 will set if SCM detects battery 2 voltage range less 8.5 volts or more than 16.3 volts for more than 2 seconds. DTC B0846 will store as a history code in SCM memory. No driver warning will be displayed. DTC can only set as history even if malfunction is current.

Under all fault conditions, DTC B0846 will clear automatically when battery 2 voltage range is 8.5-16.3 volts for more than 2 seconds. Current and history DTCs can be cleared using scan tool or Instrument Panel Cluster (IPC) clearing DTCs feature.
