Action

Yes

Was the “SRS Diagnostic System Check" performed?

Go to Step 2

Go to the “SRS

Diagnostic System

Check."

1. Malfunctions within the “AIR BAG" warning lamp circuitry will

set this diagnostic trouble code.

2. These malfunctions are addressed in the “SRS Diagnostic

System Check" via Chart B and Chart C.

3. Failure to properly perform the “SRS Diagnostic System

Check" may result in misdiagnosis.

4. Ignition switch “ON."

5. Clear SRS diagnostic trouble codes.

Is DTC 61 SET?

DTC 71 Internal SDM Fault

D09RX002

Circuit Description:

Diagnostic Trouble Code (DTC) 71 is an indication of a
potential internal Sensing and Diagnostic Module
(SDM) malfunction and will set if any of the following
conditions are detected:
1) Deployment or microprocessor energy reserve
failure.
2) Electronically Erasable Programmable Read Only
Memory failure. (EEPROM).
3) Random Only Memory failure. (ROM).
4) Random Access Memory failure. (RAM).
5) Calibration check sum failure.
6) Deployment switch faults.
7) Accelerometer fault.
8) Arming sensor fault.
9) Diagnostic current faults.
10) DTC 19
11) DTC 25
12) DTC 51

13) DTC 53

DTC Will Set When:

Any of the above indicated malfunctions are detected by
the SDM. The malfunctions described above are
tested mainly during “Continuous Monitoring" and some
ones run each ignition cycle.

Action Taken:

SDM turns “ON" the “AIR BAG" warning lamp and sets
a diagnostic trouble code.

DTC Will Clear When:

A scan tool “Clear Codes" commanded is received by
the SDM. Some of the indicated malfunctions will only
allow the “AIR BAG" warning lamp to go out.
But when DTC 19, 25, 51, 53 are also set, SDM is
Replaced.

DTC 71 Internal SDM Fault

WARNING:  DURING SERVICE PROCEDURES. BE
VERY CAREFUL WHEN HANDLING A SENSING AND
DIAGNOSTIC MODULE (SDM).  NEVER STRIKE OR
JAR THE SDM.  NEVER POWER UP THE SRS WHEN
THE SDM IS NOT RIGIDLY  ATTACHED TO THE
VEHICLE. ALL SDM AND MOUNTING BRACKET
FASTENERS MUST BE CAREFULLY TORQUED
AND THE ARROW MUST BE POINTING TOWARD
THE FRONT OF THE VEHICLE TO ENSURE PROPER
OPERATION OF THE SRS. THE SDM COULD BE
ACTIVATED WHEN POWERED WHILE NOT RIGIDLY
ATTACHED TO THE VEHICLE WHICH COULD
CAUSE DEPLOYMENT AND RESULT IN PERSONAL

INJURY.

CAUTION: When Diagnostic Trouble Code (DTC) 19
or 25 or 51 or 53 has been set it is necessary to
Replace the SDM. Setting DTC 19 and 25 or 51 or 53
will also cause DTC 71 to set. When a scan tool
“CLEAR CODES" command is issued and the
malfunction is no longer present, DTC 51 or 53 and
DTC 71 will remain current. Ensure that the short to
voltage condition DTC 19, 25 is repaired prior to
installing a Replacement SDM to avoid damaging
the SDM.

Step

Action

Yes

Was the “SRS Diagnostic System Check" performed?

Go to Step 2

Go to the “SRS

Diagnostic System

Check."

Note SRS “Diagnostic System Check."
Is DTC 19 or 25 or 51 or 53 also set (current or history)? (Refer to
notice above).

Go to DTC 19 if

DTC 19 is set.

Go to DTC 25 if

DTC 25 is set.

Go to DTC 51 if

DTC 51 is set.

Go to DTC 53 if

Service Precaution

WARNING:  THIS VEHICLE HAS A SUPPLEMENTAL
RESTRAINT SYSTEM (SRS). REFER TO THE SRS
COMPONENT AND WIRING LOCATION VIEW IN
ORDER TO DETERMINE WHETHER YOU ARE
PERFORMING SERVICE ON OR NEAR THE SRS
COMPONENTS OR THE SRS WIRING.  WHEN YOU
ARE PERFORMING SERVICE ON OR NEAR THE
SRS COMPONENTS OR THE SRS WIRING, REFER
TO  THE SRS SERVICE INFORMATION.  FAILURE TO
FOLLOW WARNINGS COULD RESULT IN POSSIBLE
AIR BAG DEPLOYMENT, PERSONAL INJURY, OR
OTHERWISE UNNEEDED SRS SYSTEM REPAIRS.

CAUTION:  Always use the correct fastener in the
proper location. When you replace a fastener, use
ONLY the exact part number for that application.
ISUZU will call out those fasteners that require a
replacement after removal. ISUZU will also call out
the fasteners that require thread lockers or thread
sealant.  UNLESS OTHERWISE SPECIFIED, do not
use supplemental coatings (Paints, greases, or
other corrosion inhibitors) on threaded fasteners or
fastener joint interfaces. Generally, such coatings
adversely  affect the fastener torque and the joint
clamping force, and may damage the fastener.
When you install fasteners, use the correct
tightening sequence and specifications.  Following
these instructions can help you avoid damage to
parts and systems.
