DTC B0136/74 OPEN IN P/T SQUIB (LH) CIRCUIT
CIRCUIT DESCRIPTION
The P/T squib LH circuit consists of the airbag sensor assy center and the \
front seat outer belt assy LH (seat
belt pretensioner LH).
This circuit actuates the SRS to deploy when the SRS deployment conditio\
ns are fulfilled.
DTC B0136/74 is recorded when an open circuit is detected in the P/T squ\
ib LH circuit.
