I know, most everyone hates this dreaded light. Trouble is, mine d/n come on ever...06 Charger SRT8. Trying to verify if system is working or not.
Car was in a wreck years ago and Drivers airbag was deployed...one of the things I found when I first got the car...Horn d/n work...deployed airbag was reinstalled instead of replaced. I replaced Airbag, Steering control module, clock spring, and column. Tried the gage cluster self test by pushing the odometer trip button, turning key on, then releasing trip button, all other lights test including gage needles...no airbag light.
No codes set except U0184 and U0186...which are no comms with Radio, no comms with Audio amp (has an aftermarket Pioneer stereo system installed). I verified good power to occupant restraint controller on C2 pins 16 and 24. Passenger side Switch bank works as advertised. Diagrams don't show the airbag signal that lights the light in the temp gage part of the cluster? Does show an Indicator Dimmer Signal coming from Switch bank pin-6 to Cluster-C3 pin-2, but that looks like its maybe a signal to decrease the light intensity of the pass side "Air Bag Off Light" for driving at night, or when you turn the cluster lights down. seems like I'm missing a diagram that shows the pin-out from OCC to gage cluster-Air bag light? I've looked through 8W-43-2 to 43-7 numerous times and only page -2 comes close, but shows passenger side interface.
I think system is ok, because the OCC is self testing the Passenger side seat sensor and works the pass side light on or off accordingly. light in the cluster could be burned out, as I have no SRS codes (U0184 and U0186 are SRS codes, but are for radio and amp?) Anyone know a way to verify the lite on the cluster? I took the rear cover off the cluster and its a circuit board...no old fashioned lights. Not even sure if it runs off 12v or a lower voltage. I hate to throw $75-$100 at a new cluster that may or may not fix the light.

Well, since they reinstalled the deployed airbag they must have disabled the light somehow otherwise it would have been on all the time.

Maybe you should turn around your thought process and start looking at how folks disable airbag lights when they do things like that. It might lead you to the answer.

 

[Mainiac1]

Good point. I asked the place that rebuilt the car that very question, but no one could answer the question...they didn't remember working on the car.

Came up with Zilch on how to permanently disable the airbag light. Still thinking the gage cluster light is out, but I read somewhere the airbag light is accompanied by a chime...and getting no chime, though I do from the TPM system? I hate to bring it to Dodge for them to throw parts at it till they really decide to troubleshoot, all at $125/hour. No SRS/gage cluster experts out there huh?

SERVICE AFTER AN AIRBAG DEPLOYMENT



DRIVER AIRBAG

After a Driver Airbag has been deployed due to a collision, the following MUST be replaced:


Driver Airbag
Clockspring Assembly
Steering Wheel
Complete Steering Column Assembly w/Lower Steering Column Coupler
All other airbag and vehicle components should be closely inspected following any airbag deployment, and should be replaced when visible damage is incurred.
WARNING: Do not connect the battery negative cable (Refer to 10 - Restraints - Diagnosis and Testing) . Personal injury or death may result if the system test is not performed first.


PASSENGER AIRBAG

After a Passenger Airbag has been deployed due to a collision. the following MUST be replaced:


Passenger Airbag
Instrument Panel Top Pad Assembly
All other airbag and vehicle components should be closely inspected following any airbag deployment, and should be replaced when visible damage is incurred.
WARNING: Do not connect the battery negative cable (Refer to 10 - Restraints - Diagnosis and Testing) . Personal injury or death may result if the system test is not performed first.


CURTAIN AIRBAG

After a Curtain Airbag has been deployed due to a collision, the following MUST be replaced:


Curtain Airbag Assembly
Headliner
A, B, and C-Pillar Trim on deployed side.
All other airbag and vehicle components should be closely inspected following any airbag deployment, and should be replaced when visible damage is incurred.
WARNING: Do not connect the battery negative cable (Refer to 10 - Restraints - Diagnosis and Testing) . Personal injury or death may result if the system test is not performed first.


OCCUPANT CLASSIFICATION SYSTEM (OCS)



NOTE: FOR ALL MARKETS: As of 12/23/2005, for cars without side airbags, and as of 01/05/2006 for cars with side airbags, the Passenger Airbag Disable (PAD) lamp is no longer functional. It is still present, but will not illuminate at any time.
After an impact event, either front, rear, or side, the OCS system components need to be inspected and replaced if found to be damaged.
This includes:


Occupant Classification Module (OCM)
Passenger Airbag Disabled Indicator
Seat Weight Sensor
WARNING: Never replace both the Occupant Restraint Controller (ORC) and the Occupant Classification Module (OCM) at the same time. If both require replacement, replace one, then perform the Airbag System test (Refer to 10 - Restraints - Diagnosis and Testing) before replacing the other. Both the ORC and the OCM store Occupant Classification System (OCS) calibration data, which they transfer to one another when one of them is replaced. If both are replaced at the same time, an irreversible fault will be set in both modules and the OCS may malfunction and result in personal injury or death .
Whether replaced or not, the OCS must be re-zeroed to make sure that the system in within proper parameters to sense the occupants weight correctly.
WARNING: Do not connect the battery negative cable (Refer to 10 - Restraints - Diagnosis and Testing) . Personal injury or death may result if the system test is not performed first.
WARNING: Following successful completion of the Airbag System test procedure, the Occupant Classification System Verification Test must be done using a scan tool and the appropriate diagnostic information. Personal injury or death may result if the system test is not performed.


SEAT BELTS AND TENSIONERS

After a frontal impact where an airbag has been deployed due to a collision, the following MUST be replaced:


Front Seat Belt and Retractor (driver and passenger) with integral Tensioners.
WARNING: Do not connect the battery negative cable (Refer to 10 - Restraints - Diagnosis and Testing) . Personal injury or death may result if the system test is not performed first.
All other seat belts should be closely inspected for cuts, tears, fraying, or damage in any way following any frontal impact or airbag deployment. The other seat belts are to be replaced when visible damage is incurred. Inspect the Lower Anchors and Tether for CHildren (LATCH) child restraint anchors for damage after an impact event and replace as needed.

Richd, thanks for the info. I had come across that info, probly in the service manual I have on my computer. The car was in a front impact that deployed the drivers airbag only I think. I did replace all the steering components as well as the drivers side seatbelt assy as that was setting a pre-tensioner code. The ORC and OCM appear to be fine and the only codes set are U0184 and U0186...Radio and radio amp because an aftermarket radio and amp are installed. While troubleshooting this problem (no airbag light) on Sat, I induced 2 codes when I disconnected the pass air bag switch bank to check continuity between the ORC and switch bank...B1206 and B1204...Pass airbag indicator circuit open and pass ind circuit Low....if the airbag light in the cluster was shorted or open, I should see the similar codes being set for it, which I don't. The harnesses going to ORC and cluster and pass airbag switch bank look factory taped/untampered with, and 12v and ground is getting to the ORC per diagram. The car is smart enough to detect a shorted or open bulb, but is not detecting such for the airbag light. Not sure which module does this this, so there is a slim chance the cluster module reports its own faults and is bad, not sure. Would be nice to see the input wire that drives the light, but don't see it on the diagrams. Its possible its a data signal that the cluster turns into a driver for the airbag indicator. Possible the ORC lamp output is bad, or ORC internal failure, but I should be getting a code for this, as the ORC is making the pass airbag switch light function normally. I am leary about Dodge throwing parts at it because when I asked them to look at the Tire Pressure Monitor System I've been trying to diagnose for months, they quoted replacing all 3 transponders for $640....the chances of all 3 transponders being bad is a very low, yet that's what they proposed as a 1st step. I don't think they even looked for codes on the system.

The thing is you dont know whoever replaced the airbag,did some shortcuts,& they couldnt get AirBag light to go out,& cut some wires.
