Bump,
Once I localize the issue in a circuit via parasitic draw testing through yanking fuses or disconnecting equipment I'll run a voltage drop test after I make sure it's getting power, and OHm's out right.
The time scale for it to drop is odd, it's immediately 110 then drops down to eventually 49 but it isn't slow enough to watch etc.
It seems to drop steady when the BCM fuse is pulled or if it's installed, so I don't think it it's the BCM. There isn't a immediate difference.
Lights in the...
Yeah so it was pulling 110mA immediately when connecting leads but slowly drops to about 60 then eventually through out pulling fuses (to hopefully see an immediate difference in draw and pinpoint AT LEAST the affected system/circuit)
It eventually settles in between 49-48mA
KOEO of course.
Battery was replaced in January, 12.3 was my reading but this is not after a charge. It was when I showed up on site. Guy said the battery charged and tested fine at the local parts store prior.
lack of the 2nd battery in what appears to be a battery location on the driver side by the front apron seems it may have had one at one time but It doesn't any longer. I'll double check for the wiring but I didn't immediately notice any disconnected battery cables in the vicinity. The main...
Thanks for the response,
We did do a amperage draw test while the vehicle was off, I posted that above in the post but maybe I didn't explain well. In summary It was about 110.0 and slowly dropped to about 49.3 throughout the whole process. However we never saw a drastic change or difference...
Back at it again, this time with a GMT900!
I have a buddy that owns a 2013 Z71 Tahoe 4x4, it is pretty much loaded. It was however outfitted as a PPV vehicle. He is the 2nd owner.
I appears to have the whole 9 besides the rear seat delete for suspect containment. However it has a partial...
Gentlemen, I found what I believe is the issue.
EBCM Solution Video
Long story short, the ignition cylinder was shot, we replaced it with a cheap Dorman model, that came with two keys and a fob.
Well after replacing the turn signal stock I discovered that the ignition cylinder gets stuck and...
10-4 just ordered the MDI2 clone linked above, I think I'm gonna hit some Goodwill's for a cheap laptop today. Should be here Monday so I'll probably get back with you when If I can't get it programmed.
I'll write up a summary in this thread too that way 5 years from now someone can find the...
I'm gonna pick up the eBay right now, but I may look into that Autel maxiflash for myself eventually, does that one operate the same as this MDI2 clone?
I'm going to pickup a laptop specifically for this kind of stuff, probably a cheap Thinkpad with windows 10.
All I need to do is download...
I'm going to check the grounds on the driver side body mount tomorrow and clean them off, apparently that's where the EBCM grounds itself. I'm still thinking either this EBCM is faulty internally or it needs to be programmed.
Alright, 30 minute ride and all speed sensors functioning fine, no drop in speed, lack of data etc. check their connections and wiggled them a good bit to see if a code set, nothing.
Removed the EBCM connector and cleaned it out with some contact cleaner. All pins and everything looks fine. No...
Going to paste here all the "Conditions required to set " according to Alldata
P0856
The PCM receives an invalid requested torque signal for 3 seconds
P1689
The PCM detects open or shorted delivered torque signal voltage as being less than 4.75 volts or greater than 5.25 volts.

I live in Georgia.
Lights came on, pulled codes.
Researching now.
side note, windshield wiper functions fine Key on Engine off, then intermittent function while on, but that's for a later date to solve lol.
I currently have a Autel MaxiCheck MX900, it's relatively inexpensive and it's been amazing for diagnostic work etc.
What exactly were you going to say? I'm basically waiting for the codes to re-appear to capture them if that's what you're wondering.
Hmm, I'm gonna search Alldata and try to find out if they are infact separate. I was thinking the might share a signal together via like a CANBUS to the same module because I only every have INOP wipers when I have INOP cruise and those illuminated lights. Cannot repeat the issue otherwise.
I'm...
Understood,
Found one single listing on eBay with a new Module for $450
Seems like that specific part # is very slim pickins. EBCM on Ebay
However I cannot verify other than the listing, and I no longer have the original module either, I do however remember making sure the part numbers...
When the lights come back on I'll attempt to have my roommate leave it running and grab codes.
I'm more than willing to pay for a GM pass through device, do you have a model number or a link to that, plus the location /website for the subscription? I'd much rather pay for that setup and find...
Currently showing the following DTC's for reference. I'm researching via Alldata now.
DTC C0196 Yaw Rate Circuit
DTC C0283 Mode Switch Circuit Malfunction
DTC C0455 Front Steering Position Sensor Circuit
or
DTC C0455 Front Steering Position Sensor Circuit
It doesn't specify which one of the...
Running into a wall with the EBCM, but made another thread for that specific issue.
Going to recharge by weight this Wednesday when I get time and report back here. If she's all solved I'll try and detail out my procedure for future folks with the same issue
Alright gentlemen, this is my progress on my EBCM debacle and I'm grasping at straws now to find a solution, so hopefully someone can assist.
I have a 2005 Tahoe Z71 4x4 with the stablitrack / JL4 EBCM module.
We replaced the module due to no communication with the scan tool.
We had success...
