Code U017E Description

The U017E code indicates that the vehicle's onboard computer has lost communication with the Seatbelt Pretensioner Module 'A'. The Seatbelt Pretensioner Module is responsible for activating the seatbelt pretensioners in the event of a collision to tighten the seatbelt and reduce the risk of injury to the occupant. When communication with this module is lost, it can impact the vehicle's safety systems and potentially compromise the effectiveness of the seatbelt pretensioners in case of an accident. This issue can also trigger the vehicle's airbag warning light to illuminate on the dashboard.

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.
