By the way, you can actually read the DTCs using just a jumper wire:
With the ignition off, jump the CG and TC pins on the OBD connector:
Attachment 39321
Turn the ignition on and watch the ABS light. If there are stored DTCs, It will flash in a pattern to indicate the code (71 for example will be shown as 7 quick flashes, a short pause, and then one quick flash).
