Code B2792 Lincoln Description

The B2792 diagnostic trouble code (DTC) for Lincoln vehicles indicates a cross link between firing loops. This code typically points to an issue with the communication between the engine control module (ECM) and the ignition system. In modern vehicles, the ECM controls the ignition timing and firing of the spark plugs to ensure proper combustion in the engine cylinders. A cross link between firing loops suggests that there is a communication error or interference that is disrupting the timing and coordination of the ignition system.

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.
