DTC B0107/51 SHORT IN P SQUIB CIRCUIT (TO GROUND)
CIRCUIT DESCRIPTION
The P squib circuit consists of the airbag sensor assy center and the instr\
ument panel passenger airbag
assy.
This circuit actuates the SRS to deploy when the SRS deployment conditions a\
re fulfilled.
DTC B0107/51 is recorded when a short to ground is detected in the P squ\
ib circuit.

INSPECTION PROCEDURE
1 CHECK INSTRUMENT PANEL WIRE(P SQUIB 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 instrument panel passenger airbag assy.
(d) Measure the resistance between the body ground and P+ of the connector ºCº.
OK:
