Open in Squib Circuit
DIAGNOSTIC CHARTDIAGNOSTIC CHART
The squib circuit consists of the center airbag sensor assembly, spiral cable and the steering wheel pad
(squib). It causes the airbag to deploy when the airbag deployment con\
ditions are satisfied.
For details of the function of each component, see FUNCTION OF COMPONENT\
S on page AB±5.
Diagnostic code 14 is recorded when an open is detected in the squib cir\
cuit.

INSPECTION PROCEDURE
(1) Disconnect battery negative (±) terminal cable, and wait at least 20 seconds.
(2) Remove steering wheel pad (See page AB±14).
Measure resistance between D+ and D± on spiral
cable side of connector between spiral cable and
steering wheel pad.
Preparation.
Resistance: Below 1
When storing steering wheel pad, keep upper sur-
face fo the pad facing upward.
Disconnect center airbag sensor assembly connec-
tor.

Diag. Code 15\
\
Open in Front Airbag Sensor Circuit
CIRCUIT DESCRIPTION
The front airbag sensor detects the deceleration force in a frontal collisi\
on and is located in the front fender
on the left and right sides.
For details of the function of each component, see FUNCTION OF COMPONENT\
S on page AB±5.
Diagnostic code 15 is recorded when an open is detected in the front air\
bag sensor circuit.
NOTICE: The front airbag sensor connector is equipped with an electrical connection \
check mechanism
for the purpose of detecting an open in the front airbag sensor (See page AB±7). This mechanism is
constructed so that when the terminals of the front airbag sensor have been connect\
ed (when the connec-
tor housing lock is in the locked condition), the connection detection \
pin on the wire harness side connects
with the terminals for diagnosis use on the sensor side. If the connector is\
not properly connected, the diag-
nosis system may detect only a malfunction code, even though the airbag syste\
m is functioning normally.
When connecting the front airbag sensor connector, make sure it is connected properly. If diagnostic code
15 is displayed after the front airbag sensor connector has been connect\
ed, check again that it is properly
connected.
Code No.
