Diagnostic Procedure
DIAGNOSTIC INFORMATION AND PROCEDURES CHART (LOSS OF IGNITION RUN ONLY)
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition on. Ensure the battery is fully charged.
NOTE:
For the purpose of this test, the AECM and ORC modules will be referred to as an ACM. SELECT ACTIVE : ACM - ACTIVE DTC Go To 2
NOTE:
When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.

| 2 | Turn the ignition off. Remove and inspect the Airbag Run circuit fuse. Is the Fuse open? Yes --> Go To 3 No --> Go To 6 |
All |
| 3 | Remove the Airbag Run fuse.
NOTE:
Check connectors - Clean and repair as necessary. Measure the resistance of the Fused Ignition Switch Output Run circuit between the Run Fuse and ground. Is the resistance below 10.0 ohms ? Yes --> Go To 4 No --> Replace the defective 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. Disconnect the Airbag Control Module connector.
NOTE:
Check connectors - Clean and repair as necessary. Measure the resistance of the Fused Ignition Switch Output Run circuit between the ACM connector and ground.Is the resistance below 10K ohms ?Yes --> Repair the Fused Ignition Switch Output Run circuit for a short to ground and replace Airbag Run Fuse.Perform AIRBAG VERIFICATION TEST - VER 1 .No --> Go To 5 |

| 5 |
WARNING:
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. If there are no possible causes remaining, view repair.RepairReplace the Airbag Control Module in accordance with Service Instructions and replace the Run Only Fuse.Perform AIRBAG VERIFICATION TEST - VER 1 . |
All |
| 6 | Turn the ignition on. Measure the voltage of the Ignition Switch Output Run circuit between the Airbag Run circuit fuse and ground. Is the voltage above approximately 4.5 volts? Yes --> Go To 7 No --> Repair the open Ignition Switch Output Run circuit. Perform AIRBAG VERIFICATION TEST - VER 1 . |

WARNING:
TO AVOID PERSONAL INJURY OR DEATH, TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING. Disconnect the Airbag Control Module connector.
NOTE:
Check connectors - Clean and repair as necessary.
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. Reinstall the airbag Run 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 circuit at the Airbag Control Module connector.Is the voltage above approximately 4.5 volts?Yes --> Go To 8No --> Repair the an open or high resistance in the Fused Ignition Switch Output Run circuit.Perform AIRBAG VERIFICATION TEST - VER 1 . |
