Unfortunately, the ABS system has been disconnected on my car. I don't miss it except that it doesn't indicate if the OVP is working. I took the OVP apart and couldn't see anything wrong inside. The zener diode looks good, but I didn't test it. I likely will later. I am mostly concerned with how to get the car to the mechanic; both shops I go to are 40+ miles away. I should buy a trailer or tow bar with the number of times I have to move my family's dead cars.
