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.

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.

General Description

The cruise control keeps the vehicle running at a fixed
speed until a signal canceling this fixed speed is received.
When the main switch “AUTO CRUISE” is turned on with
the vehicle in the running mode, the battery voltage is
applied to the PCM.  When a signal from the control
switch is input to the PCM while the vehicle is in this state,
the cruise control system is activated.  Also, while the
system is operating, the “AUTO CRUISE” indicator light in
the meter assembly lights up.

1 . SET/COAST Switch Function

1. Set Function: When the SET/COAST switch is

pressed and released with the main switch on, the
speed at which the vehicle is running at that moment
is stored in the memory, and the vehicle automatically
runs at the speed stored.

2. Coast–Down Function: When the SET/COAST

switch is keep on while the vehicle is running, the
vehicle decelerates during that time.  The speed at
which vehicle is running when the control switch is
turned off is stored in the memory, and the vehicle
automatically returns to the stored speed.

3. Tap–Down Function: When the SET/COAST

switch is turned on and off instantaneously while the
vehicle is running, the vehicle decelerates for each
on/off operation.  The vehicle speed at which the
vehicle was running when the SET/COAST was
turned off last is stored in the memory, and the vehicle
automatically returns to this stored speed.

2 . RESUME/ACCEL Switch Function

1. Resume Function: When the RESUME, ACCEL

switch is turned on/off after the system is temporarily
deactivated by pressing the brake or clutch pedal
while the vehicle is running, the vehicle resumes,  the
speed stored before the system was released.

2. Accelerate Function: When the RESUME/ACCEL

switch is keep on after the system is released
completely, the vehicle accelerates its speed during
that time.  The vehicle speed at which the vehicle was
running when the switch was turned off is stored in the
memory, and the vehicle automatically returns to this
speed.

3. Tap–Up Function: When the RESUME/ACCEL

switch is turned on and off instantaneously while the
vehicle is running, the vehicle accelerates a mile for
each on/off operation.  The vehicle speed at which the
vehicle was running when the switch was turned off
last is stored in the memory, and the vehicle
automatically returns to this stored speed.

3 . CANCEL Function

1. Temporary Cancellation: 

D

When the cancel switch is turned on.

D

When the brake pedal is pressed.

D

When the clutch pedal is pressed. (M/T)

D

When the select lever is shifted to any position other
than “D”, “3”, “2” or “L”. (A/T)

D

When the vehicle speed has decreased about 20
km/h or more than the stored speed.

D

When the vehicle speed gets lower than 32 km/h.

2. Complete Cancellation: 

D

When the starter switch or the main switch is turned
off.

D

When the failsafe function is activated.

Brake Switch

Removal and Installation

Refer to Brake Pedal Replacement in Brake section.

Adjustment

1. Check that the brake pedal (3) is fully returned by

pedal return spring.

2. Disconnect the switch connector.
3. Loosen the lock nut (2).
4. Rotate the brake switch (1) by hand until push rod

disappears from brake switch tip (4).

5. Return the brake switch by a half turn.
6. Tighten the lock nut.
7. Connect the switch connector.
