air bag light??

Can't say why you have a light other than some fault. Worst case in ignoring it would be that the air bags don't deploy in an accident.

 

Jerry, did this include not disconnecting the plugs on the instrument binnacle? The airbag system also knows if the airbag warning light is not connected. If the binnacle plugs are not connected and you turn on the ignition at some point during your refurbishment, the airbag warning light will come on later (when the car is back together again).

 

Do we know this 100%? I recall Grant mentioning it. Jerry - you need a Ferari SD or Leonardo to reset an airbag fault. But, you also want to diagnose the fault. Maybe I should unplug my instrument cluster under power and see if I get a fault. Given I have an SD it's no issue.

 

Yes this is true.
Pain in the butt but still true

 

Just to clarify... Are you saying it stayed illuminated after startup, but not appeared half way through a trip? If it came on half way through a trip, we may have to offer other theories.

 

Jerry, the best tool is a factory SD. A Leonardo may work. That's the only options.

 

@Dave rocks can you here me test test beep beep of the tag feature

 

I saw the post Tim but no other notification

 

cool just chaecking the tag option put @ then the username to notify that person

 

Jerry, it all depends. If the fault was triggered due to an electrical connection being disconnected under power, then yes. But, if you have some other issue sending the fault signal, that will need to be connected. Here are some screen shots of the airbag ECU taken via my SD2. Thake a look at the first error page - it shows "LAMP" as an error. That maybe the lamp in the instrument cluster Grant is talking about and if you scan yours for errors and "lamp" is lite, that may confirm the fault. I'm just too busy now or I would unplug mine and check.

Well, you need the SD X to check the fault. If it was juts because the dash pod was disconnected, and it is now connected, then a reset should do it. If there is another fault you will need to correct it.

edit: Dave, you beat me to it.

And yes, the lamp error is generally the dash light. It's telling you the light circuit is open, as in burnt out bulb or disconnected. You will find a similar fault for the CEL.

 

Maybe this is a dumb question, but if the dash light is burnt out how would it light up to warn the operator of the vehicle?

 

Well, I guess I'm trying to understand what fault will be recorded for disconnecting the instrument cluster under power. Based on you post, "Lamp" would mean a blown bulb, not a disconnection.

 

No theres plan b

Send it to your fchat buddy Dave and for a nominal fee he can reset it.
Then when you do your stickies hes your man.

Or ship it to a dealer they charge 100 bucks

 

I guess i should read first
Maybe not the problem??

 

Actually, Jerry - Grant is correct. If you ship me your ECU, I'll read and clear the faults by installing it in my car. You just need to give me time as I'm very busy.

 

I would expect that the ECU looks at the lamp circuit and expects to see a current draw when the lamp is supposed to be on, like at start up. Disconnected or burnt out lamp, either way, when the lamp is supposed to be illuminated, but the circuit is open, the ECU will not see a current draw triggering a lamp error.

 

Hey Dave, you could do the same thing for my HVAC ECU, no? I think you need another 355 that you can use just for testing/resetting air bag and HCAV ECUs, and maybe ABS ECUs too, and maybe main engine ECUs. People can pull their ECU and sent them to you. You can install them in one of your (working) cars (you need both 2.7 and 5.2), read the codes, reset them and send them back with a list of the trouble codes found. You can call it ECU Rx RRR service: Remote Read and Reset service. (I want 15%)

 

Hey John - I sincerely have a better idea:

You are retired, bored and nursing that bady toe - how about you design me a test rig so I can power up these ECU's on a bench? I think the biggest issue would be sending all the proper inputs to not cause other faults.

 

It ends right there...
