DTC report AHC C1718 & C1776, ABS C1223 & C1241 (1 Viewer)

What is the slee override? isn't that if you remove the AHC stuff?

I get a stored air bag code whenever I unplug/plug the one under the passenger seat for removal. I don't remember which one exactly though. Yours is the circuit itself indicating a short I believe. You notice the x in the history column for SRS code.

• The center airbag sensor assembly receives a line short signal, open signal, short to ground signal or B+ short signal in the passenger airbag ON/OFF indicator circuit for 2 seconds. • Passenger airbag ON/OFF indicator malfunction • Center airbag sensor assembly malfunction

install a new battery and drive a while, re read codes again. if he'll let you. Sounds like a few sensors and a battery. But I know nothing of AHC.

I personally start my truck and then hook up TS and do live data checks. I've only driven with techstream hooked up one time, while I was looking at fuel and AFR stuff.

This one sounds like it's right up your alley. Hopefully he wants to ditch it for the trouble is has?

C1223 and C1241 codes..... Somewhere along the line the C1241 code set and this code means that there was low-voltage to the ABS actuator motor. This could be due to a low state of charge in the battery or the alternator not correctly putting out enough power or the battery simply being run low at some point. By default then the C1223 code sets in the traction control computer detecting a malfunction in the ABS control computer which makes sense because of the C1241 code.

I found these two when I bought mine, I had to go back and look to male sure. Then I found the above, copied from online.
So new battery might/should fix three of them.

c1718, maybe this pic helps you.

c1776 thread here, Height sensor dead in 05LX

So that one might be crummy one to deal with looks like. If he thought the accumulators were bad maybe that's why he went with the override thing.

if you need anything I have all the 06 books

you shouldn't get a code at 12.7 Mine sits at 12.8 right now after sitting for three days. I find that the new stock battery likes to sit there, even for two weeks without a battery tender on it.
I would imagine, at one point yours was dead and set the code, then recharged. Unless you have a new battery that the guy put in for you.
Personally I don't mess around with batteries, if they look old or of unknown age and don't measure up I get a new one.
For me it makes it easier to determine the starter and alt condition afterward on used cars I buy.

I did find that cleaning and swapping ground straps to 4 gauge wire improved my circuit. I bet yours would benefit from cleaning all those stock lugs. Since you're going to resell it I bet it's worth trying to save that battery also.

Looks like you hit the nail on the head here.

After cleaning & greasing the very dry battery post, I gave it a full charge. Subsequently I cleared all the DTC's and they did not returned. Interesting DTC stores as a current without a CEL, and continued to show current even after full charge and multiple starts & stops. But as I said. they've not returned so I'm happy.

Let me know how that works for you

Looks like the boots are good, so I'll probably just re-banding. IIRC the NAPA bands are crimp so I my yet get to try the banding crimp tool on this restoration project.

The only thing I'm still getting is a "Engine and ECT: Monitor Status; Inc, Calibration; 36065200" I'm new to using TechStream, so please excuse my ignorance, what is this?

I don't know what that is either. I have it also. I think it relates to the controller or the OBD2 port.

or session ID. IDK!!

New toy is here

I could've used that last weekend. My old boot clamp tool, which has worked great on a handful of VWs and Audis, wasn't up for the task. Those yellow clamps are d@mn strong.

You need access to the TIS site to see what that is specifically. You'll always see that code as the calibration update has been applied.

I'm not a subscriber, and didn't know if I could update with one of these $30 Chinese cables.

So what will this do for me?

To bad you're not in my Colorado, you could of used mine.

Inc = Incomplete? In the System Selection menu what color is the Engine & ECT box: Yellow- White-
see pic.

Boot clamps: If you dont mind, could you take some width measurements on the Napa bands: mm width measurement compared to the OEM bands- curious to know if they are the same width. Could you post a pic or part # of the NAPA band clamp as well?

I believe it was white on all Health checks, but not in my save. I'll make sure to note next hook up.

Thanks for the links, I'll read thought before next hook up.

I'll will post the NAPA (if I use) sizes in Swony's thread as work progress.
