I still can't believe I connected battery backwards. Car is V6. Blew 100 amp fuse in under hood fuse box. Replaced this and now ABS, TCS, Brake and E-Brake warning lights stay on while car is running. Car runs and drives fine but ABS is definitely not working. As well ABS module was clicking while battery terminals were reversed. Checked all other related fuses in under hood fuse box and they are fine. Is there something else I can test before taking her in to the stealership?

Hi Lobster63. My daughter just did the same thing and has the same problem with the lights. I had to replace the ABS module.
