I just completed my first differential oil change on my 2022 Mach 1 and I used a jumper wire on the thermal switch connector to cycle the oil cooler pump but nothing happens except an instrument panel warning to reduce speed. I've seen video's where this simple hack (I don't have ForScan) is used to activate the pump so now I'm concerned my pump isn't functional? Thank you for any guidance.
