HCU was replaced today, and I haven’t seen the codes in the 4 minutes as I took it to drive back home.

I hit the road on Wednesday and have my fingers crossed that the ABS and TCS lights don’t come back.

Current miles are 17,600 on 18’ 3500; yes, miles are low.

I lived in Oahu for four years.

I’ll update this thread if it happens again.

The current plan is to use alpha OBD to read codes while I’m on the road if they pop back up.
