possible Transmission Control Switch (TCS) problem
Hi,
I ran a test on my EECIV and it came up with a DTC concerning the Transmission Control Switch saying that it did not change state during the KOER test. I was wondering if there was a way to test this switch? Is it a common problem? I dont seem to be having any transmission problems at the moment, but i would like to find out why I'm getting this code. Thanks!!

I am not sure exactly what the transmission control switch is, but make sure you also state the year and some other specs that you know about your truck(year, engine size, type of tranny, f150, 250, etc.)

It can only change state if you switched it on and off during KOER... IE you needed to turn the wheel for PSPS switch if equipped, hit Brake lamp switch for BOO test, and toggle the trans overdrive switch off and on.
