DTC B0136/74 Open in P/T Squib (LH) Circuit
CIRCUIT DESCRIPTION
The P/T squib circuit (LH) consists of the airbag sensor assembly and seat belt pretensioner (LH).
It causes the SRS to deploy when the SRS deployment conditions are satisfied.
For details of the function of each component, see OPERATION on page RS±2.
DTC B0136/74 is recorded when an open is detected in the P/T squib (LH) circuit.
