Code B1495 Hyundai Description

The B1495 code for Hyundai vehicles indicates a belt tension sensor defect. The belt tension sensor is a crucial component in the vehicle's engine system, responsible for monitoring the tension of the belts that drive various engine components such as the alternator, water pump, and power steering pump. When the sensor detects abnormal tension in the belts, it sends a signal to the engine control module (ECM) to adjust the tension accordingly. A malfunctioning belt tension sensor can lead to incorrect tension adjustments, potentially causing the belts to slip or break, resulting in engine performance issues and possible damage to other components.

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.
