With the DRBIII
t, record and erase all DTC’s from all Airbag modules.
If equipped with Passenger Airbag On - Off switch, read the DTC’s in all switch
positions.
If any ACTIVE codes are present they must be resolved before diagnosing any stored
codes.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors.
Look for chaffed, pierced, pinched, or partially broken wires and broken, bent, pushed
out, spread, corroded, or contaminated terminals.
The following additional checks may assist you in identifying a possible intermittent
problem.
Reconnect any disconnected components and harness connector.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION ON, THEN RECONNECT THE BATTERY.
With the DRBIII
t monitor active codes as you work through the following steps.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, MAINTAIN A SAFE
DISTANCE FROM ALL AIRBAGS WHILE PERFORMING THE FOLLOWING
STEPS.
Wiggle the wiring harness and connectors of the related airbag circuit or component.
If codes are related to the Driver Airbag circuits, rotate the steering wheel from stop
to stop.
IF only stored codes return continue the test until the problem area has been isolated
In the previous steps you have attempted to recreate the conditions responsible for
setting active DTC in question.
Are any ACTIVE DTCs present?
All
Yes
→ Select appropriate symptom from Symptom List.
No
→ No problem found at this time. Erase all codes before returning
vehicle to customer.

Symptom List:
LEFT SIDE IMPACT SENSOR 3 INTERNAL 1
NO LEFT SIDE IMPACT SENSOR 3 COMMUNICATION
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be LEFT SIDE IMPACT SENSOR 3
INTERNAL 1.
When Monitored and Set Condition:
LEFT SIDE IMPACT SENSOR 3 INTERNAL 1
When Monitored:
At ignition on, the Left Side Impact Sensor 3 is equipped with onboard
diagnostics to monitor the sensors internal circuits. If a problem is identified the sensor
sends the Left Side Impact Sensor 1 internal 1 message to the ACM.
Set Condition:
The code will set, if the ACM receives an Impact Sensor Internal 3
message from the Left Side Impact Sensor 1.
NO LEFT SIDE IMPACT SENSOR 3 COMMUNICATION
When Monitored:
The ACM continuously communicates with the Left Side Impact
Sensor 3 over the sensor signal circuit. The sensor communication and onboard diagnostics
are powered by the ACM signal.
Set Condition:
The code will set, if the ACM and Left Side Impact Sensor 3 do not
establish and maintain valid data communications.
POSSIBLE CAUSES
SIGNAL CIRCUIT SHORTED TO BATTERY
SIGNAL CIRCUIT SHORT TO GROUND
LEFT SIDE SENSOR 3 CIRCUITS SHORTED TOGETHER
SIGNAL CIRCUIT OPEN
ACM, LEFT SIDE IMPACT SENSOR 3
REPAIR IS COMPLETE
STORED CODE OR INTERMITTENT CONDITION

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
Disconnect the Left Side Impact Sensor 3 connector.
Disconnect the Airbag Control Module connector.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION ON, THEN RECONNECT THE BATTERY.
Measure the voltage of the Left Side Impact Sensor 3 Signal circuit and sensor
ground at the Left Side Impact Sensor 3 connector.
Is there any voltage present?
All
Yes
→ Repair the Left Side Impact Sensor 3 Signal circuit shorted to
battery.
Perform __AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 3
3
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION
ON, THEN RECONNECT THE BATTERY.
Measure the resistance of the Left Side Impact Sensor 3 Signal circuit between the
Left Side Impact Sensor 3 connector and ground.
Is the resistance below 100K ohms?
All
Yes
→ Repair the Left Side Sense 3 Signal circuit shorted for a short to
ground.
Perform __AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 4
4
Measure the resistance between the Left Side Impact Sensor Signal and Sensor
Ground circuits at the Left Side Impact Sensor connector.
Is the resistance below 100K ohms?
All
Yes
→ Repair the Left Side Impact Sensor 3 circuits shorted together.
Perform __AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 5
5
Measure the resistance of the Left Side Impact Sensor 3 Signal circuit between the
Left Side Impact Sensor 3 connector and the Load Tool adaptor.
Is the resistance below 1 ohm?
All
Yes
→ Go To 6
No
→ Repair the Left Side Impact Sensor 3 Signal circuit open or high
resistance.
Perform __AIRBAG VERIFICATION TEST - VER 1.

Replace the Left Side Impact Sensor 3.
Reconnect the vehicle body harness to the impact sensor.
Remove any special tools or jumper wires and reconnect all previously disconnected
components - except the Battery.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION ON, THEN RECONNECT THE BATTERY.
Connect the DRB to the Data Link Connector - use the most current software
available.
Use the DRB III and erase the stored codes in all airbag system modules.
Turn the Ignition Off, and wait 15 seconds before turning the Ignition On.
Wait one minute, and read active codes and if there are none present read the stored
codes.
DID the active Left Side Impact Sensor 3 DTC return?
All
Yes
→ Go To 7
No
→ Repair is complete.
Perform __AIRBAG VERIFICATION TEST - VER 1.
