That's not the case.. if it needs calibrating it won't show any DTCs and also if broke
The brake issue did not happen until the wires in the ass end got melted, shorted,
and that does not cause the brake pedal switch to suddenly get out of alignment ?
You really think the controllers are going to allow NO DTCs while the PCM sees the gas pedal engaged, the MPH going up, high RPMs,
higher engine loads, higher MAP readings, torque and brake lights ON non-stop as if that pedal switch was degraded with closed position ?
Suggest you look at the PIDs & DTCs for the EBTCM and the BCM and look at what trips "limp" mode
So in your thinking, the switch can be broken, EBTCM see the wheels speed sensors MPH going down, due to brake on and
just ignore it or the brakes on, but the same controller says MPH is increasing
Limp mode and DTCs were not designed for no reason much less ABS
