AIRBAG SYSTEM, Diagnostic DTC:B0130/63

DTC Code DTC Name
B0130/63 Short in Front Pretensioner Squib RH Circuit

DESCRIPTION

The P/T squib (RH) circuit consists of the airbag ECU assembly and seat belt pretensioner (RH).

It causes the SRS to deploy when the SRS deployment conditions are satisfied.

DTC B0130/63 is recorded when a short is detected in the P/T squib (RH) circuit.

INSPECTION PROCEDURE

PROCEDURE


  1. CHECK P/T SQUIB(RH) CIRCUIT (AIRBAG ECU ASSEMBLY-FRONT SEAT OUTER BELT ASSEMBLY RH)


    1. A01KHODE01
      Text in Illustration
      *1 P/T Squib (RH)
      *2 Airbag ECU Assembly

      Disconnect negative (-) terminal cable from the battery, and wait at least for 90 seconds.

    2. Disconnect the connector between the airbag ECU assembly and the seat belt pretensioner (RH).

    3. Release the airbag activation prevention mechanism of the connector (on the airbag ECU assembly side) between the airbag ECU assembly and the seat belt pretensioner (RH) Click here.

    4. For the connector (on the seat belt pretensioner side) between the seat belt pretensioner (RH) and the airbag ECU assembly, measure the resistance between PR+ and PR-.

      OK
      Resistance: 1 MΩ or Higher
