DIAGNOSIS
DIAGNOSTIC TROUBLE CODE (DTC)
When the sensing and diagnostic module (SDM) detects
any problem it illuminates the airbag warning indicator and
stores the diagnostic trouble codes (DTCs).
The supplemental inflatable restraints (SIR) diagnostic
system check must be always the starting point for any
SIR diagnosis. The diagnostic system check reveals diag-
nostic trouble codes (DTCs) through the use of scan tool.
It also checks for proper airbag warning lamp operation.
The two types of DTCs that may be recorded are as fol-lows :
1. Active DTCs represent malfunction being detected
during the current ignition cycle. Active DTCs are
stored in random access memory (RAM).
2. Historic DTCs represent malfunctions detected sin-
cethe last time the historic memory was cleared.
Historic DTCs are stored in the electrically erasable
programmable read–only memory (EPROM).

SIR DIAGNOSTIC SYSTEM CHECK
Notice : If the vehicle interior has been exposed to exten-
sive water intrusion such as water leaks, driving through
high water, flooding, or other causes, the sensing and
diagnostic module(SDM) and SDM connector may need
to be replaced. With ignition OFF, inspect the area around
the SDM, including the carpet. If any significant soaking or
evidence of previous soaking is detected, the water must
be removed, water damage repaired, and the SDM and
the SDM connector must be replaced. Before attempting
any of these repairs, the supplemental inflatable re-
straints(SIR) must be disabled. Refer to ”Disabling the
SIR” and ”Sensing and Diagnostic Module(SDM)” in this
section for instructions on how to disable the SIR and re-
place the SDM.
The SIR Diagnostic System Check must always be the
starting point for any SIR diagnosis. The Diagnostic Sys-
tem Check reveals diagnostic trouble codes(DTCs)
through the use of scan tool. The diagnostic procedures
used in this section are designed to find any repair SIR
conditions. To get the best results, it is important to use the
diagnostic charts and follow the sequence listed below.
1. Perform the SIR Diagnostic System Check, which
reveal diagnostic trouble codes(DTCs) through theuse of scan tool.. It also checks for proper airbag
indicator operation.
2. Refer to the proper diagnostic chart as directed by
SIR Diagnostic System Check. Bypassing these
procedures may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replace-
ment.
3. Repeat the SIR Diagnostic System Check after any
repair or diagnostic procedures have been per-
formed to ensure that the repair has been made
correctly and that no other malfunction exists.
Circiut Description
When the ignition switch is first turned to ON, ignition volt-
age is supplied from airbag fuse to find the SDM at input
terminal A1. The SDM responds by flashing the airbag in-
dicator seven times and then turning it off while the SDM
performs tests on the SIR.
Diagnostic Aids
The order in which DTCs are diagnosed is very important.
Failure to diagnose the DTCs in the order specified may
result in extended diagnostic time, incorrect diagnosis,
and incorrect parts replacement.
SIR Diagnostic System Check
CAUTION : The sensing and the diagnosis module
(SDM) can maintain surfficient voltage to deploy the
airbags and pretensioners for 1 minute after the igni-
tion is OFF and the fuse has been removed. If the air-
bags and pretensioners are not disconnected, do not
begin service until one minute has been passed after
disconnecting power to the SDM. Otherwise, injury
could result.
CAUTION : During service procedure, be very careful
when handling the SDM. Never strike or jar the SDM.Never power the supplemental inflatable re-
straints(SIR) when the SDM is not rigidly attached to
the vehicle. All SDM mounting bolts must be carefully
tightened , and the arrow on the SDM must be point
toward the front of the vehicle to ensure proper op-
eration of the SIR. The SDM could be activated if it is
powered when it is not rigidly attached to the vehicle,
resulting in unexpected deployment and possible in-
jury.
Step
ActionValue(s)YesNo
11. Turn the ignition switch ON.
2. Observe the airbag indicator as the ignition is
being turned ON. Does the indicator flash
seven times?–System OKGo to Step 2
21. Turn the ignition to LOCK and remove the key.
2. Connect the scan tool to the data link connec-
tor(DLC). Follow the directions given in the
scan tool manual.
3. Are any DTCs displayed on the scan tool?–Go to the
DTC check
procedureGo to Step 3
3Check the fuse F1 in the interior fuse box.
Is the fuse F1 blown?–Go to Step 4Go to Step 5
4Replace the fuse F1.–––
51. Disconnect the connector C207.
2. Check the wiring shortage between the fuse F1
and the terminal 1 of the connector C207.
3. Is the wiring shorted? Then, repair the wiring.––Go to Step 6
