Code B2762 GMC Description

The memory seat switches are normally open and are wired to the Driver Door Switch Assembly (DDSA). When a memory recall switch is pressed, the switch pulls the 5 V signal circuit from the DDSA to ground. The DDSA senses that a memory recall signal was pulled low and a serial data message is sent to the Memory Seat Module (MSM) identifying the memory request. The MSM responds to the request by commanding the driver seat to move to the preset positions. The DDSA will set the Diagnostic Trouble Code (DTC) when a short to ground is detected on a switch signal circuit or if a memory recall switch is active for 30 seconds or more.
