PASSENGER AIRBAG ON - OFF SWITCH OPEN - DIAGNOSTIC PROCEDURE

TEST	ACTION
1	NOTE: Ensure that 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. SELECT ACTIVE or STORED DTC: ACM - ACTIVE DTC Go To 2 ACM - STORED DTC Go To 5 NOTE: When reconnecting Airbag system components, the ignition must be turned off and the battery must be disconnected.
2	WARNING: TO AVOID PERSONAL INJURY OR DEATH, 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 PAB On-Off Switch resistance between terminals 1 and 2 in both switch positions.The switch resistance specifications are: ON position = 175.0 to 190.0 ohms and OFF position = 820.0 to 870.0 ohms.Is the resistance within range for both switch positions? Yes --> Go To 3 No --> Replace the Passenger Airbag ON-OFF Switch. Perform AIRBAG VERIFICATION TEST - VER 1 .
3	WARNING: IP 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. Measure the resistance of the PAB MUX Switch Sense between the ACM and the PAB On-Off Switch connector.Measure the resistance of the PAB MUX Switch Return circuit between the ACM and the PAB On-Off Switch connector.Is the resistance below 5.0 ohms on both circuits? Yes --> Go To 4 No --> Repair the open Passenger Airbag MUX Switch circuit. Perform AIRBAG VERIFICATION TEST - VER 1 .
4	WARNING: TO AVOID PERSONAL INJURY OR DEATH, TURN 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. Repair Replace the Airbag Control Module in accordance with Service Instructions. Perform AIRBAG VERIFICATION TEST - VER 1 .
5	NOTE: Ensure the battery is fully charged. With the DRBIII(R), record and erase all DTCs from all modules.All active codes must be resolved before diagnosing any stored codes.Maintain a safe distance from all airbags while performing the following steps.With the DRBIII(R) monitor active codes as you work through the system. NOTE: If equipped with Passenger Airbag On-Off switch, read the DTC's in all switch positions. Wiggle the wiring harness and connectors of the appropriate airbag system and rotate the steering wheel from stop to stop. NOTE: Check connectors - Clean and repair as necessary. You have just attempted to simulate the condition that initially set the trouble code message.The following additional checks may assist you in identifying a possible intermittent problem: Visually inspect related wire harness connectors. Look for broken, bent, pushed out, spread, corroded, or contaminated terminals. Visually inspect the related harnesses. Look for chafed, pierced, pinched or partially broken wire. Refer to SYSTEM WIRING DIAGRAMS and Technical Service Bulletins that may apply. Did the DTC become active ? Yes --> Select appropriate symptom from Symptom List. No --> No problem found at this time. Erase all codes before returning vehicle to customer.
