2025 Equinox 3K miles Ck Engine Light EMC + TCM

[MikeYESfan]

Help me..lol.... My Check engine light came on and the car is "making a crackling noise" by the all wheel drive buttons on left side of steering wheel under the dash.
My app told me to get car to dealer at 1st. Now app says all clear but "crackling noise is loud.

Dealer thinks it the radio Speaker? Let's see what happens

Radio speaker isn't going to throw a code.

To me, the takeaway here is the P2534 code:

"Diagnostic trouble code (DTC) P2534 stands for “Ignition Switch Run/Start Position Circuit Low.” The code is set once a module detects a voltage that's below the manufacturer-specified value. When you turn on your ignition, battery voltage is automatically sent to all the electrical systems in your vehicle."

Loose/bad connection? Low system voltage due to a weak battery? Like @ricklack said, this ain't a speaker problem.
