Code B0680 2017 GMC Sierra Description

The passenger air bag ON/OFF indicators are used to notify the driver when the passenger presence system has enabled or disabled the passenger instrument panel air bag. When the Inflatable Restraint Sensing and Diagnostic Module (SDM) receives the appropriate serial data message from the passenger presence module (if equipped) the inflatable restraint sensing and diagnostic module will then provide voltage to the appropriate indicator. When air bag disable switch (if equipped) has been switched to either OFF or ON, the corresponding air bag indicator will be illuminated by the inflatable restraint sensing and diagnostic module. The Diagnostic Trouble Code (DTC) will be set when the Inflatable Restraint Sensing and Diagnostic Module detects improper voltage on the control circuit of the indicator.

Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.

Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
