DTC 88 Open in Curtain Shield Airbag Squib (LH)
Circuit
CIRCUIT DESCRIPTION
The curtain shield airbag squib circuit (LH) consists of the airbag sensor assembly and curtain shield airbag
assembly (LH).
It causes the curtain shield airbag assembly (LH) to activate when the curtain shield airbag assembly (LH)
activation conditions are satisfied.
For details of the function of each component, see OPERATION on page RS–2.
DTC 88 is recorded when an open is detected in the curtain shield airbag squib (LH) circuit.

INSPECTION PROCEDURE
1 Prepare for inspection. (See step 1 on page DI–285 of Pub. No. RM599E)
2 Check curtain shield airbag squib (LH) circuit.
CHECK:
For the connector (on the curtain shield airbag assembly side)
between the curtain shield airbag assembly (LH) and the airbag
sensor assembly, measure the resistance between ICL+ and
ICL–.
OK:
Resistance: Below 1 Ω
NG Repair or replace harness or connector be-
tween curtain shield airbag assembly (LH) and
airbag sensor assembly.
