(b) Using a service wire, connect PL+ and PL± of the connec- tor ºCº.
NOTICE:
Do not forcibly insert a service wire into the terminal of the
connector when connecting.
(c) Connect the negative (±) terminal cable to the battery, and wait for at least 2 seconds.
(d) Turn the ignition switch to the ON position, and wait for at least 10 seconds.
(e)Clear the stored DTCs in the memory (See page
05±1184).
(f) Turn the ignition switch to the LOCK position.
(g) Turn the ignition switch to the ON position, and wait for at least 10 seconds.
(h)Check the DTCs (See page 05±1184).
OK:
DTC B0136/74 is not output.

DTC B0135/73 SHORT 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 conditions are fulfilled.
DTC B0135/73 is recorded when a short circuit is detected in the P/T squib LH circuit.
