Anyone ever had this problem -- intermitent airbag light
You know the idiot/diagnostic light that shows an airbag symbol (right under the fasten seatbelt)? Sometime mine will illuminate randomly while driving. It goes on/off sporadically. No check engine light or anything.
Any thoughts as to what it is? Have it scheduled to go in April 2nd. Beside the airbag light my only other complaint is the squeaky hatch. |

In my C6 Convertible I've been stuck with that problem off and on since I got the car. They have changed the seat belts and that fixed it for awhile then they said was a wiring harness problem and that again fixed it for awhile. Just had them look at it again so time will tell. Got 68K on the speedo |

Seatbelts? That sounds like a dog chasing it's own tail! I wonder if GM switched the design or manufacturer of electrical connectors -- seems to be a fair amount of electrical gremlins in the C6.
As for the observation about electrical gremlins, you've obviously never owned a BMW or Mercedes.:lol: As all cars get more complex with more on-board computers and sensors, the gremlin issue is becoming more and more common across the board. Actually the C6 generation seems to be doing better than industry average among cars with similar complex electronics. |

Foosh -- I don't think this is a result of the complexity of the car, but just an honest something wasn't put in right. A bad connection or sensor somewhere. Hey the car still runs and I'm still enjoying it. Furthermore, I'm not going to knock GM for this. However, doesn't mean it's still not an annoyance. |

My other comment regarding complexity was in response to your statement that the C6 seems to be plagued by many electrical gremlins. I've seen many other makes far worse, than the C6 experience thus far. |
With Recaros replacing the stock seats I have this idiot light all the time. Does your car have the 2LZ option with seat mounted side air bags? If so you might try wiggling around the connectors under both seats. Always try the easy stuff first, sometimes you get lucky! :thumbs:

There are a few factors to consider WRT the SIR system, and the idiot light. Having been through this with an unsuccessful seat swap in my Z06, I'm unfortunately all too familiar with it. Some of the things that can cause the SIR MIL:
1. Connectors aren't connected properly. 2. BCM is malfunctioning. 3. Seat position sensors (driver and/or passenger) aren't reading proper electric current. 4. Passenger Presence Sensor (butt-sensor in passenger seat) isn't working, or isn't connected. 5. Seat belt pre-tensioners (driver or passenger) are malfunctioning. Any of these failures will cause the SIR MIL to come on, and completely disable the entire system. It'll take a Tech-2 to get the codes from the BCM. Once you have those codes, it'll be real easy to figure out what's going wrong. Good luck. jas |

Regardless, this is an excellent idea! Are these the standard wires under the seats? I'm guessing there is a connector somewhere along the way -- will scope it out. |

The pax airbag light stays off, so I am thinking it is not #4
and the seat belt light goes out so it's probablly not #5. jas |

Don't be too sure. Have someone sit in the passenger seat and watch the rear-view mirror. Does the message change to indicate the airbag is armed?

Again, don't be too sure. Seat belt pretensioner codes don't illuminate the seat belt light. They illuminate the SIR MIL. I speak from direct experience on that one.
jas Unfortunately I am limited to checking for any obviously lose connectors, and will have to see what the Tech II says when I bring it into the dealer. Too bad the dealer**** could not just hook it up to the scanner when I stopped in Friday and see where the error was. Stay tuned I guess. |
Mine does the same thing. Although, over the past week, it hasn't come on at all. Sometimes it will stay lit for 5 minutes straight before going back out. I'm worried that the air bags may randomly deploy while I'm driving!

The results of that investigation revealed that a freak pebble had scored a direct, bulls-eye impact on the chassis-mounted sensor. Thus, the system did "see an impact." It did what it was supposed to do, but obviously, that was an early design flaw based on sensor location. I believe the sensors are now better shielded. Bottom line from my research on this, is that the airbags can only deploy when the sensor records an impact of a certain force. If the airbag light is on, they are disabled and cannot deploy. The sensor system is pretty much industry-standard, varying only with sensor location in a particular model. |
Well the code was B0041 so the dealer is going to dig around and hopefully have a resolution.

Terry DTC B0040, B0041, or B0045 Circuit Description The driver side deployment loop consists of the following components: An inflatable restraint side impact module - LF The inflatable restraint side impact module wiring harness The side impact module - LF high circuits The side impact module - LF low circuits A shorting bar is used within the side impact module - LF connector. The shorting bar will short together the side impact module - LF high circuit, and the side impact module - LF low circuit when the connector is disconnected. This helps prevent unwanted deployment of the inflator module during servicing. During a side or frontal crash of sufficient force, the inflatable restraint sensing and diagnostic module (SDM) will allow current to flow through the deployment loop. This flow of current will deploy the side impact module - LF. The SDM performs continuous diagnostic tests on the deployment loops to check for proper circuit continuity and for shorts to ground or voltage. If a malfunction is detected, a DTC will be stored in memory. DTC Descriptors This diagnostic procedure supports the following DTCs: DTC B0040 Left Front Side Deployment Loop Resistance Low DTC B0041 Left Front Side Deployment Loop Open DTC B0045 Left Front Side Deployment Loop Voltage Out of Range Conditions for Running the DTC Ignition 1 voltage is within the normal operating voltage range. Conditions for Setting the DTC DTC B0040 will set when the side impact module - LF deployment loop resistance is less than 1.3 ohms for 500 milliseconds. DTC B0041 will set when one of the following conditions occurs: Side impact module - LF high circuit is less than 2.4 volts and the side impact module - LF deployment loop is more than 6 ohms for 500 milliseconds. Side impact module - LF deployment loop resistance is more than 4.8 ohms for 500 milliseconds. DTC B0045 will set when one of the following conditions occur: Side impact module - LF high and/or low circuits is short to ground or short to voltage for 500 milliseconds. Side impact module - LF high circuit is less than 2.4 volts and side impact module - LF deployment loop resistance is less than 6 ohms for 500 milliseconds. Action Taken When the DTC Sets The SDM commands the AIR BAG indicator ON via class 2 serial data. Conditions for Clearing the DTC The condition responsible for setting the DTC no longer exists and the scan tool Clear DTCs function is used. A history DTC will clear once 255 malfunction-free ignition cycles have occurred. Diagnostic Aids The following are possible causes of the malfunction: A short between the side impact module - LF high and low circuits An open or a high resistance in the side impact module - LF high or low circuits A short to ground or a short to voltage in the side impact module - LF high or low circuits The side impact module - LF connector The SDM connector A malfunctioning side impact module - LF A malfunctioning SDM Thoroughly inspect the wiring and the connectors. An incomplete inspection of the wiring and the connectors may result in a misdiagnosis, causing a part replacement with the reappearance of the malfunction. If an intermittent malfunction exists, refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems. Test Description The numbers below refer to the step numbers on the diagnostic table. This step tests to see if the malfunction is caused by the side impact module - LF or by the side impact module - LF wiring harness. This step tests to see what DTCs are present. If DTC B0040 s present, test the side impact module - LF for a short between high and low circuits. If DTC B0041 is present, test the side impact module - LF high and low circuits for an open and for high resistance.

Mine did this took it in and the plug under the seat was not seated all the way.

anyone have a solution to seat changes and airbag lights and so on. I'd love to get a nice race seat in for the track then switch it back out w/o all kinds of dummy lights going on
