2015 Escalade Alarm sounding after remote start session ends and code P10E4

[AaronIROCZ]

Having issues with a 2015 Escalade we acquired recently. First it pops the engine code P10E4 randomly, usually right after startup. ( Ignition on/start circuit source bypass relay control performance ) I have researched the code and it states common issue is the headlight wiring suffering from water intrusion, I have checked multiple times and the plugs are dry and I even replaced the plugs with new pigtails and the code seems to persist. I had access to the GM service manual and not much was stated in it with that code. Here in Houston Texas it has been colder in the mornings (lower 20's) and it sat for 3 days without starting it and when I turned on the key the message battery low start engine came up when I was reading the codes. Battery was replaced on November. It started slower than normal but hasn't ever been completely dead yet. I have HP tuners but I don't want to just disable the code as it "seems" to be having a battery drain issue. I have also replaced the under hood fuse block with another used unit due to bent/corroded pins as well as a new ECM Relay and the problem still persists.

Problem 2, whenever the remote start completes a cycle, runs for 12 minutes and shuts off or doesn't start due to a check engine light 30 seconds goes by and the alarm siren/horn is triggered. Nobody touches the car or keys to set it off. Any ideas?

Is your rear defrost broken?

Yes both tabs to the glass are not attached. I tried resoldering them but couldn't get it to stick. Looking for a replacement rear glass.

That’s the cause of your alarm after remote start. I read somewhere that it’s tied into the alarm system somehow. I’ve had a broken tab up until this past summer. My alarm stopped going off after that was fixed

You can remote start, then unlock for the time being if you want to avoid the alarm blaring.

Also if you haven’t tried, I’ve heard frost fighters is really good for tab replacements.

For the battery drain,

Water in the headlamp and related wiring can cause that code.


Other things may cause it as well. The valvtronic junk is for BMW engines. On any other vehicle including GM its basically saying a accessory circuit that should be key on power is getting power when it should not be (bypassed). Could be water somewhere or a short or a relay. This one may take some chasing to find. Possibly either the wiring/circuit or the relay that control ECM startup is bad/flaky

any aftermarket accessory? Anything plugged into the OBD port?

I found this from another thread about that code first off. For problem number 2 it is definitely the rear defroster. My 2015 GMC Yukon XL and it was a specific glue to put the connectors on, not a solder. This is what I used: https://www.napaonline.com/en/p/PTX...mS-vqo5zOwuN7owkvbORa-NnO8YfZ7oYaAmN0EALw_wcB

Also noticed the buttons around the radio display screen are staying lit up after it is shut off. Checked it after it wasn't touched for 30 minutes and they were still lit up. The shock button that changes the ride settings doesn't work either. Could this be a failing bcm?
