Driver Anchor Pretensioner operates as well as Belt Pretensioner at the same time If it gets into its deploy condition after a collision. It is located at near anchor on driver seat and it is an equipment to make up for the existing short stroke. Driver Anchor Pretensioner is supported by two cable and it is an auxiliary equipment to prevent a driver from breaking away doubly as seat belt is being pulled toward achor side after a collision.
Never measure resistance of Anchor Pretensioner front-Driver directly, Current of measuring device may cause unexpected airbag depoy.
If you strike or spin the SRSCM at the IG "ON" state, the seat-belt pretensioner, curtain-airbag or side-airbag could be unfolded and bring on danger. Handle it with care.
The SRSCM sets DTC B1733 if there is a short to power in Anchor Pretensioner front-Driver harness.
*In this case, SRSCM checks if there's any fault in circuit by sending current for a while.
