Diagnostic Procedure

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
DIAGNOSTIC PROCEDURES - LOSS OF IGNITION RUN - START

TEST ACTION APPLICABILITY
1 Ensure the battery is fully charged.
Turn the ignition on.
NOTE: For the purpose of this test, the AECM and ORC modules will be referred to as an ACM.

DETERMINE ACTIVE OR STORED DTC:
ACM - ACTIVE DTC
Go To 2
ACM - STORED DTC
Go To 8
NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.
 All
2 Turn Ignition off.
Remove and inspect the Airbag Run - Start Fuse.
NOTE: Check connectors - Clean and repair as necessary.

Is the Fuse open?
Yes --> Go To 3
No --> Go To 5		 All
3 Measure the resistance of the Fused Ignition Switch Output Run-Start circuit between the Airbag Run - Start Fuse and ground.
Is the resistance below 10.0 ohms?
Yes --> Go To 4
No --> Replace Airbag Run - Start Fuse.
Perform AIRBAG VERIFICATION TEST - VER 1 .		 All
4
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND PERSONAL INJURY OR DEATH.
Disconnect the Airbag Control Module connector
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ACM Adaptor to the Airbag Control Module connector(s).Measure the resistance of the Fused Ignition Switch Output Run-Start circuit between the ACM Adaptor and ground.Is the resistance below 10K ohms?Yes --> Repair the Fused Ignition Switch Output Run - Start circuit short to ground.Perform AIRBAG VERIFICATION TEST - VER 1 .No --> Replace the Airbag Control Module in accordance with Service Instructions.Perform AIRBAG VERIFICATION TEST - VER 1 .		 All
5 Turn the ignition on.
Measure the voltage of the Ignition Switch Output circuit at the Airbag Run - Start fuse.
Is the voltage above approximately 6.0 volts?
Yes --> Go To 6
No --> Repair the open Ignition Switch Output Run - Start circuit.
Perform AIRBAG VERIFICATION TEST - VER 1 .
NOTE: Reinstall the fuse after performing this test.

WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND PERSONAL INJURY OR DEATH.
Disconnect the Airbag Control Module connector.
NOTE: Check connectors - Clean and repair as necessary.
Connect the appropriate Load Tool ACM Adaptor to the Airbag Control Module connector(s).Reinstall the previously removed Airbag Run-Start Fuse.
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION ON, THEN RECONNECT THE BATTERY.
Measure the voltage of the Fused Ignition Switch Output Run - Start Circuit at the ACM Adaptor.Is the voltage above approximately 6.0 volts?Yes --> Go To 7No --> Repair open Fused Ignition Switch Output Run-Start circuit.Perform AIRBAG VERIFICATION TEST - VER 1 .		 All
7
WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING.
WARNING: IF THE AIRBAG CONTROL MODULE IS DROPPED AT ANY TIME, IT MUST BE REPLACED. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND PERSONAL INJURY OR DEATH.
If there are no possible causes remaining, view repair.RepairReplace the Airbag Control Module in accordance with Service Instructions.Perform AIRBAG VERIFICATION TEST - VER 1 .		 All
8 With the DRBIII®, 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 IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE 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 IGNITION ON, THEN RECONNECT THE BATTERY.

With the DRBIII® 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?
Yes --> Select appropriate test.
No --> No problem found at this time. Erase all codes before returning vehicle to customer.		 All
