Code B1C2E Jeep Description

The B1C2E diagnostic trouble code (DTC) indicates a fault in the airbag system, specifically relating to the right side seat thorax squib 1. The term "squib" refers to the small explosive device used to deploy the airbag in the event of a collision. When this code is triggered, it suggests that the squib circuit has shorted together, which means there is an unintended connection that could lead to improper airbag deployment or a failure to deploy altogether.

The total repair time may vary from 1 to 4 hours, depending on the complexity of the issue.

When is the Code Detected?

This Diagnostic Trouble Code (DTC) sets when the Occupant Restraint Controller (ORC) detects both circuits of the same squib are shorted together for more than 2.5 seconds. This DTC transitions from active to stored when the module sees a recovery from the shorted together condition for greater than 2.5 seconds.

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.
