after it is repaired and the monitors are run, then the codes are cleared. if you clear it now, freeze frame data will be erased for the repair tech.

You can go to auto zone let them run the problem code for you OR unhook the battery both sides press the horn after you finish to drain all current. leave it overnite before you rehook. worked for me! At least overnite ok!
