Default Brake light switch

After replacing speed control sensor in differential, replacing the complete ABS module (pump and circuit board located on the drivers side fender), I took it to a shop where a friend of mine worked that had a fancy Snapon scanner that supporte ABS trouble codes and it said BRAKE LIGHT SWITCH CLOSED. My brake lights still worked and it was hard for me to believe my brake light switch was bad but I replaced it anyway. When removing the switch mounted just over the brake pedal, I noticed there were 6 wires to the plug and the plunger seemed to have a broke spring internally because the plunger would not extend fully withou help. I bought a new one from Autozone and that fixed my problem. If I had done the scan in the beginning it would have saved me some big bucks and labor chasing the problem of "ABS AND BRAKE LIGHT ON". I'm not sure but the code stored in the ABS module may have to be erased also, but I changed my switch at my friends shop and erased the code after the installation of switch.
