Diagnostic Procedure
DIAGNOSTIC INFORMATION AND PROCEDURES - PASSENGER OFF INDICATOR CIRCUIT SHORT TO GROUND
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition on.
NOTE:
Ensure that 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 or STORED DTC: ACM - ACTIVE DTC Go To 2 ACM - STORED DTC Go To 10
NOTE:
When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.

| 2 | With the DRBIII®, read active Airbag Control Module DTC's. Does the DRBIII® display LOSS OF IGNITION RUN - START ? Yes --> Refer to symptom list for problems related to LOSS OF IGNITION RUN - START active diagnostic trouble code test. Perform __AIRBAG VERIFICATION TEST - VER 1 . No --> Go To 3 |
All |
| 3 | Is this vehicle equipped with a Passenger Airbag On - Off Switch? Yes --> Go To 4 No --> With the DRBIII® in MISCELLANEOUS, read the Configure for Airbag ON - OFF Switch current status. Enter the number 1 and press enter to re configure the ACM for NO AIRBAG ON/OFF SWITCH. Perform __AIRBAG VERIFICATION TEST - VER 1 . |
All |
| 4 | Gain access to the Passenger Airbag On - Off Switch connector. Is the Passenger Airbag On - Off Switch connected to the dash harness? Yes --> Go To 5 No --> Connect the Passenger Airbag On - Off switch to the dash harness connector. Perform __AIRBAG VERIFICATION TEST - VER 1 . |

WARNING:
TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING. Disconnect the Passenger On - Off Switch connector.
NOTE:
Check connectors - Clean and repair as necessary.
WARNING:
TO AVOID PERSONAL INJURY OR DEATH, TURN IGNITION ON, THEN RECONNECT THE BATTERY. Measure the voltage on the Fused Ignition Switch Output Run - Start circuit between the PAB On - Off Switch connector and ground.Is the voltage above 10.0 volts?Yes --> Go To 6No --> Repair the open Fused ignition Switch Output Run - Start circuit.Perform __AIRBAG VERIFICATION TEST - VER 1 . |

WARNING:
TURN THE IGNITION OFF, DISCONNECT THE BATTERY AND WAIT TWO MINUTES BEFORE PROCEEDING. Disconnect the Passenger Airbag On - Off Switch.
NOTE:
Check connectors - Clean and repair as necessary. Measure the resistance between PAB On - Off Switch terminals 3 and 4.Is the resistance approximately 14 ohms?Yes --> Go To 7No --> Replace the Passenger Airbag ON - OFF Switch in accordance with the service information.Perform __AIRBAG VERIFICATION TEST - VER 1 . |
All |
| 7 | 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. Connect the appropriate Load Tool ACM Adaptor to the Airbag Control Module connector(s). Measure the resistance of the PAB Indicator Driver circuit between the ACM and the PAB On - Off Switch connector. Is the resistance below 5.0 ohms? Yes --> Go To 8 No --> Repair the open Passenger Airbag Indicator Driver circuit. Perform __AIRBAG VERIFICATION TEST - VER 1 . |
All |
| 8 | Measure the resistance of the PAB Indicator Driver circuit between the PAB On - Off Switch connector and ground. Is the resistance below 10K ohms? Yes --> Repair the Passenger Airbag Indicator Driver circuit short to ground. Perform __AIRBAG VERIFICATION TEST - VER 1 . No --> Go To 9 |

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 . |

| 10 | 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 symptom from Symptom List. No --> No problem found at this time. Erase all codes before returning vehicle to customer. |
