Code B1038 Infiniti Description

The B1038 code in an Infiniti indicates a fault with the crash zone sensor. This sensor is a critical component of the vehicle's safety system, as it is responsible for detecting impacts and deploying airbags or other safety measures in the event of a collision. When this sensor malfunctions, it can compromise the overall safety of the vehicle and its occupants. The crash zone sensor is typically located in the front of the vehicle and uses accelerometers to detect sudden changes in velocity that indicate a crash.

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.
