When you have problems with your EZGO PDS golf cart, you know, the ones with the forward/reverse switch on the dash, you can enter the golf cart into diagnostics mode to help find out what is wrong with it.
To enter PDS diagnostics mode turn the key switch off, move the run/tow switch to run, move the direction switch from neutral to reverse 5 times. Your cart will beep to confirm you are in diagnostics mode. Soon after, the carts diagnostics code will beep out your code if there is a problem. After receiving your beep code move the run/tow switch to tow.
