Problem:
Tried to program 2023 Silverado 1500 today. It’s proximity fob. I cannot access the ecm. Using Autel KM100.
I had cable plugged in. I had WiFi. I tried auto vin and it pulled vin but couldn’t parse so had to manually do it. Tried the diagnostic scan. Tried hot function. Everything just keep saying it couldn’t access the even.
Solution:
You can only do up to 2022 on all after-market tools. 2023 IS SPS2!! KNIFE KEY!! Need OEM software for that one. or buy the pin code. sps2 is the easiest way.
You need a laptop, J2534 box, Sps2 software, a sps2 subscription.
The truck is CAN-FD and KM100 doesn’t support it.
You can always use the VCI200 from the KM100 with a USB cable and run GM’s Techline Connect. 45 USD subscription for that VIN and program keys at will.
