So, I have a 2015 Freightliner Cascadia. It is an automatic. The check engine light comes on and off. Here recently so does the ABS and wheel spin light. They usually go away. Well now the ABS, HSA, and check engine light is on. I clicked the switch to try to turn the HSA back on but it won’t turn off. My dash looks like a Christmas tree right now. Can some one please advise me as what this could mean I have been with this company 2 months and this is already the third truck and many times…
