LEFT CURTAIN OR SEAT SQUIB SHORT TO GROUND
When Monitored:
With the ignition on, the ACM monitors the resistance of the Left
Curtain or Seat Squib circuits.
Set Condition:
When the ACM detects a short to ground in either Left Curtain or Seat
Squib circuits.
POSSIBLE CAUSES
LEFT CURTAIN OR SEAT SQUIB SHORT TO GROUND
LEFT CURTAIN OR SEAT SQUIB LINE 1 OR LINE 2 SHORTED TO GROUND

FACE, THE AIRBAG WILL PROPEL INTO THE AIR IF ACCIDENTALLY
DEPLOYED.
Connect the appropriate Load Tool to the Left Curtain or Seat Airbag connector.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION
ON, THEN RECONNECT THE BATTERY.
With the DRBIII
t, read active Airbag Control Module DTC’s.
Does the DRBIII
t display LEFT CURTAIN OR SEAT SQUIB SHORT TO GROUND?
All
Yes
→ Go To 3
No
→ Replace the Left Curtain or Seat Airbag in accordance with
Service Instructions.
Perform __AIRBAG VERIFICATION TEST - VER 1.

Disconnect the Load Tool from the Left Curtain or Seat Airbag connector.
Disconnect the Airbag Control Module connector(s).
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ACM adaptor to the ACM connector(s).
Measure the resistance of the Left Curtain or Seat Squib Line 1 and Line 2 circuits
between the Left Curtain or Seat Airbag connector and ground.
Is the resistance below 10K ohms on either circuit?
All
Yes
→ Repair Left Curtain or Seat Squib Line 1 or Line 2 shorted to
ground.
Perform __AIRBAG VERIFICATION TEST - VER 1.
No
→ Go To 4

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNI-
TION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BE-
FORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY
TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRE-
CAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT
AND PERSONAL INJURY OR DEATH.
If there are no possible causes remaining, view repair.

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 FRONT IMPACT SENSOR INTERNAL 1
NO LEFT FRONT IMPACT SENSOR COMMUNICATION
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be LEFT FRONT IMPACT SENSOR
INTERNAL 1.
When Monitored and Set Condition:
LEFT FRONT IMPACT SENSOR INTERNAL 1
When Monitored:
The Left Front Impact sensors is equipped with onboard diagnostics to
monitor the sensors internal circuits. If a problem is identified the sensor sends the Left
Front Impact sensor internal 1 message to the ACM.
Set Condition:
The code will set if the ACM receives an internal 1 message from the Left
Front Impact Sensor.
NO LEFT FRONT IMPACT SENSOR COMMUNICATION
When Monitored:
The ACM continuously communicates with the Left Front Impact
Sensor 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 Front Sensor do not establish and
maintain valid data communications.
POSSIBLE CAUSES
SIGNAL CIRCUIT SHORTED TO BATTERY
SIGNAL CIRCUIT SHORT TO GROUND
LEFT FRONT SENSOR 1 CIRCUITS SHORTED TOGETHER
GROUND CIRCUIT OPEN
SIGNAL CIRCUIT OPEN
ACM, LEFT FRONT IMPACT SENSOR 1
REPAIR IS COMPLETE
