A friend of mine bought an 02 4R a few months ago. The speedo and odo weren't working, and the VSC, trac, and ABS lights were lit. He replaced the ABS module with a unit he got from a junkyard, which got the speedo and odo working, but the lights remained lit, even after multiple attempts to perform a VSC calibration.
Today the speedo and odo quit working again. Does anyone have an idea for a fix for this? I find it odd that the replacement module would've went bad, unless there is another condition in the truck that is frying these modules. Any input or guidance would be appreciated!
