DIAGNOSTICS
WARNING: Accidental air bag deployment is possible. Personal injury may result.
Read and follow all WARNINGS and AIR BAG SAFETY PRECAUTIONS
before working on air bag system or related components.
Accidental air bag deployment is possible. Personal injury may result.
Use only digital multimeter with 10 milliamp or less output rating in
smallest ohmmeter range.
SELF-DIAGNOSTIC SYSTEM
SRS includes a self-diagnostic function that checks system for faults in SRS components and related wiring. A
fault exists if AIR BAG warning light on instrument cluster continues to glow more than 6 seconds after
ignition is turned on, or glows or flashes while vehicle is driven.
RETRIEVING DIAGNOSTIC TROUBLE CODE (DTC)
NOTE: Ensure battery is sufficiently charged prior to performing diagnostic
procedures. A dead or low-charged battery may cause inaccurate test values to
be obtained.
When AIR BAG warning light is on, read DTC by connecting a HDS tester to 16-pin data link connector, and
following tester prompts to read directly from HDS tester, or reading AIR BAG warning light flashes. If AIR
BAG warning light stays on or does not come on, or side air bag cutoff warning light stays on, go to

Retrieving DTC Using Hds Tester
Ensure ignition is off. Connect HDS tester to 16-pin Data Link Connector (DLC), located under left side of
instrument panel. Turn ignition on. Following manufacturers instructions, check DTCs. Turn ignition off and
wait at least 10 seconds. Disconnect HDS tester from DLC. Perform appropriate diagnostic test. See
DIAGNOSTIC TROUBLE CODE (DTC) CHART
Retrieving DTC Using AIR Bag Warning Light
table.
1. Turn ignition off. Connect HDS tester to 16-pin data link connector, located under left side of instrument
panel. Follow tester prompts in SCS menu.
2. Turn ignition on. AIR BAG warning light will come on for about 6 seconds and go off. DTC will be
indicated next. DTC consists of a main code and a sub-code. Including most recent malfunction, up to 3
different malfunctions can be indicated. If AIR BAG warning light does not come on, check for short to
ground or open in SCS circuit before troubleshooting SRS system.
3. In case of a continuous failure, DTC will be indicated repeatedly. In case of an intermittent failure, AIR
BAG warning light will indicate DTC once, then will stay on. If both a continuous and an intermittent
failure occur, both DTC's will be shown as continuous failure. If AIR BAG warning light comes on
continuously and no DTC is detected, SRS system malfunction may be present.
4. Retrieve DTC. If DTCs are retrieved, go to DTC chart to continue diagnostics. See DIAGNOSTIC
TROUBLE CODE (DTC) CHART table. Turn ignition switch to OFF position and wait 10 seconds.
Disconnect HDS tester from data link connector.
ERASING DIAGNOSTIC TROUBLE CODE MEMORY
Erase Diagnostic Trouble Code (DTC) memory with HDS tester connected to data link 16-pin connector, or by
connecting an SCS Service Connector (07PAZ-0010100) to Memory Erase Signal (MES) connector.
Erasing DTC Memory Using Hds Tester
Connect HDS tester to 16-pin Data Link Connector (DLC). Turn ignition switch to ON position. Select DTC
CLEAR in TEST MODE MENU on HDS tester. Turn ignition switch to OFF position and wait at least 10
seconds. Disconnect HDS tester from DLC.
NOTE: Do not use a jumper wire in place of SCS service connector. Jumper wire may
be difficult to connect and disconnect quickly enough.
Erasing DTC Memory Using SCS Service Connector
1. Turn ignition off. Connect SCS Service Connector (07PAZ-0010100) to Memory Erase Signal (MES)
connector. See Fig. 30
.
2. Turn ignition on. AIR BAG warning light will come on for about 6 seconds then go off.
3. Disconnect SCS service connector from MES connector within 4 seconds after AIR BAG warning light
goes off. AIR BAG warning light will come on again.

continues to fail to initialize, replace OPDS unit.
DEFEATING SHORT CONNECTOR
When SRS unit connector is disconnected, a short circuit is created in the connector to prevent air bag
deployment. In certain diagnostic test situations, the circuit will be required to be open. When SRS Short
Canceler (070AZ-SAA0100) is installed in specified connector cavities, short connector is defeated. See Fig.
31 . Observe the following precautions, when using SRS short canceler:
To prevent damage of the connector cavity, insert the SRS short canceler straight into the cavity, from the
terminal side of connector.
Before installing SRS short canceler, wash tool with neutral detergent, then blow-dry tool with air.
DO NOT use SRS short canceler, if it is damaged.
Ensure SRS short canceler is removed prior to reconnectin
connector.
