Code B1334 Hyundai Description

The detecting system for the front crash consists of the Supplemental Restraint System Control Module (SRSCM) and two Front Impact Sensors (FIS). The Front Impact Sensors are located at both sides of the front of the engine room. When FIS delivers collision signal to SRSCM, SRSCM checks if safing sensor located in SRSCM detects collusion, and if both FIS and the safing sensor detects collision simultaneously, SRSCM operates front airbag. The SRSCM sets the Diagnostic Trouble Code (DTC) (s) if it detects that any FIS is defective or there is a communication error between any FIS and the SRSCM.

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.
