DTC B0137/71 SHORT IN P/T SQUIB (LH) CIRCUIT (TO GROUND)
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 B0137/71 is recorded when a short to ground is detected in the P/T s\
quib LH circuit.

INSPECTION PROCEDURE
1 CHECK FLOOR WIRE(P/T SQUIB LH CIRCUIT)
(a) Turn the ignition switch to the LOCK position.
(b) Disconnect the negative (±) terminal cable from the bat-
tery, and wait for at least 90 seconds.
(c) Disconnect the connectors from the airbag sensor assy center and the front seat outer belt assy LH.
(d) Measure the resistance between the body ground and PL+ of the connector ºCº.
OK:
Resistance: 1 M
or Higher
