Code B2860 Buick Description

The memory seat and telescoping steering column position settings are stored in the Left (LH) Seat Control Module (SCM). The SCM measures and stores the steering column position by using a position sensor, which is an internal part of the telescoping actuator. The SCM provides the position sensor with a 5 volt power supply, and ground. The SCM monitors the position sensor signal voltage, which ranges from 0.1-4.78 volts depending on the steering column position. The steering column position sensor becomes active only when the SCM detects a steering column switch input. The Diagnostic Trouble Code (DTC) sets when the steering column position sensor signal, to the SCM, is less than 0.1 volt or greater than 4.78 volts for 2 seconds or more.
