DTC Will Set when
SDM receives wrong ID (Part No.) signal from side-sensor.
DTC Troubleshooting1) Turn ignition switch OFF.
2) Replace driver or passenger side-sensor referr ing to “Side-Sensor Removal and Installation”.
3) Repeat “Air Bag Diagnostic System Check”.

• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

2 1) Disconnect service wire from “L11” or “L35” connector.
2) Measure voltage between “L29-46” terminal and body ground, “L29-47” terminal and body ground or “L29-44”
terminal and body ground, “L29-45” terminal and body
ground.
With ignition switch ON, is each measured value 1 V or less? Go to Step 3. DTC B1084: “WHT/
RED” circuit or “LT
GRN/BLK” circuit
shorted to power supply
circuit.
DTC B1094: “WHT/
GRN” circuit or “LT
GRN” circuit shorted to
power supply circuit.
3 1) Check side-sensor referring to “Side-Sensor Inspection”. Is it in good condition? Substitute a known-
good SDM and recheck.
Replace side-sensor
referring to “Side-
Sensor Removal and
Installation”. If DTC still
exists, substitute a
known-good SDM and
recheck.

Wiring Diagram
CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor Connections”.
• If there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The combined resistance of the side curtain-air bag (inflator) module (driver or passenger), harness wiring and
connector terminal contact is above a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in side curtain-air bag (inflator) module.
Step 2: Check side curtain-air bag initiator circuit.

Use of Special ToolsS7RS0B8208001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified. Do not use a non-powered probe
type tester.
Instructions must be followed carefully,
otherwise personal injury may result.

You should be familiar with the tools listed under the
heading “Special Tool”. You should be able to measure
voltage and resistance. You should be familiar with
proper use of a scan tool such as Air Bag Driver /
Passenger Load Tool, Connector Test Adapter Kit and
the Digital Multimeter.
Special tool
(A): 09932–76010 Connector Test Adapter Kit
This must be used whenever a diagnostic procedure
requests checking or probing a terminal.
Using the appropriate adapter in the special tool will
ensure that no damage to the terminal will occur from the
multimeter probe, such as spreading or bending.
