E350 SRS light intermittently solid

Hi, I have an 06 E350 6.0 that has a SRS light on. Ive researched this a bit and it seems everyone else with the same issue had a solid light until the issue was corrected. Mine does not seem to have any pattern to it but i noticed when its on if the vehicle is running and in park the seatbelt chime will still go off if the driver belt is not bucked and than if vehicle is in drive and its on I dont think the seatbelt chime will go off. Yesterday it started flashing 1+9 for a short time and that stopped aside from that when it comes on its always solid. The scanner i have(BAFX bluetooth with torque) shows no codes but I dont know if its supposed to show code related to this system. Does the fact the it comes and goes indicate a loose or bad connection somewhere?

Thanks

The clockspring behind the steering wheel is a common place for intermittent connections. But I would take it somewhere and see if they can read the codes. If your light is coming on, you should have a code.

So there could be a code that's independent of the flash code? Are there any consumer type scanners that can read the code?

Not sure about what scanner you would need. I found out a few years ago that yes, the government stepped in and made the OEM's abide by the OBDII standard. But the OBDII shoots straight down the middle, mainly for engine and emissions codes, and the OEM's took advantage of that and made all these other special codes just for transmissions, brakes, 4x4 systems, etc. So yes, you have to read the fine print on some of these scanners and what they will read and not read. Sorry I can't help you on which scanner you would need.

Is this a repair that a non dealer shop should be able to do?

Ask the shop if they have a scanner that can read the code. Another poster in another post said something about this software. Read about it carefully, you would think it could read all the codes a Ford would have. It looks like the software is free, you just need to buy the little box and cable to hook it up from another vendor.

https://www.forscan.org/

Sad when you have to become a computer expert to fix your car isn't it? You know these newer cars have the computing power to read the codes themselves and tell you what you need to do to fix it, but no way would the OEM'S ever let that happen.

I use forscan on my 2006 E350. I like it. I use it with this interface http://a.co/cr6ePCN

The BAFX interface is not capable of talking to the SRS module (different communications bus) and neither is the Torque app. The software and hardware mentioned by "another mike" is the minimum needed to get to the supplementary subsystems.

So there could be a code that's independent of the flash code?
No. They are equivalent. An LFC 19 on an 06 E350 indicates an open circuit in the driver's side airbag circuit.
Pinpoint Test O: LFC 19/DTC B1932 — Driver Air Bag Circuit Resistance High
Normal Operation
The restraints control module (RCM) monitors the resistance for the driver air bag ignitor by measuring the resistance at RCM C310a pins 1 and 2. If the RCM detects high resistance between these pins, it will store a diagnostic trouble code (DTC) B1932 in memory and flash lamp fault code (LFC) 19 (or higher priority code if one exist) on the air bag indicator.
Possible Causes
Driver air bag high resistance could be caused by:
  • a faulted clockspring.
  • faulted wiring, terminals or connectors.
  • a faulted driver air bag module.
  • a faulted RCM.
Does the fact the it comes and goes indicate a loose or bad connection somewhere?
Yes, although that intermittent may be internal to a component somewhere in the system.

I just tackled this exact issue this past weekend on a different vehicle, airbag light coming on and then going off at random times. It turned out to be a broken conductor in the ribbon cable inside the clockspring. As the steering wheel was moved back and forth even slightly the two broken ends of the conductor would make and break connection, in turn causing the intermittent SRS light. I replaced the clockspring and the problem is gone.

I brought it to a shop today and of course the light stayed off and they said there was nothing they could do. The issue shows itself in two forms either the light will remain solid or sometimes it will flash a code. Assuming I get a scanner that can do this and am able to scan it while the light is on, will I get anymore specific data?

I did not get that "1 + 9" thing in your first post, but apparently that is your code. A previous poster said what that code is already. The clockspring would be a good guess as to what is wrong with it.

That's lame of them since the SRS module stores all codes until they are cleared with an SRS scan tool. All they had to do was connect an SRS scan tool and it would have told them what happened.

All the scan tool would have done is reinforce what we already know, but just with a Bxxxx DTC, probably a B1932.
