DTC 87 Short in Curtain Shield Airbag Squib (LH)
Circuit
CIRCUIT DESCRIPTION
The curtain shield airbag squib (LH) circuit 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 87 is recorded when a short is detected in the curtain shield airbag squib (LH) circuit.

WIRING DIAGRAM
See page DI–21.
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.
PREPARATION:
Release airbag activation prevention mechanism of the con-
nector (on the airbag sensor assembly side) between the airbag
sensor assembly and curtain shield airbag assembly (LH).
(See page DI–1)
CHECK:
For the connector (on the curtain shield airbag assembly side)
between the curtain shield airbag assembly (LH) and airbag
sensor assembly, measure the resistance between ICL+ and
ICL–.
OK:
Resistance: 1 MΩ or Higher
NG Repair or replace harness or connector be-
tween curtain shield airbag assembly (LH) and
airbag sensor assembly.

2. DESCRIPTION OF DISPLAY AND BUTTONS
AF: Current Value Malfunction (Blinking at current failure)
Diag: DTC (Example: 064 Flame sensor break)
Mamory Clear button: Deletion of faulty memory (Press both buttons together for longer than 2 sec.)
> Button: Scroll up of faulty memory (The past 5 codes can be stored.)
< Button: Scroll down of faulty memory (The past 5 codes can be stored.)
3. FAULTY MEMORY
The ECU is able to store up to 5 pieces of faulty memory. If it is full, the new data is written over F5.
4. WIRING DIAGRAM
Wire colors are indicated by an alphabetical code.
B=Black W=White BR=Brown L=Blue R=Red G=Green Y=Yellow
The first letter insicates the basic wire color and the seconk letter indicates the color of the stripe.
