Cm 2350 dead batteries now check eng. Light

[Nilao]

When my batteries started to fail I had ABS Module failure-root cause unknown codes in my ecm....so I think having low voltage causes these issues. I would reset it after you get new batteries and see if it comes back.

As for the reason the batteries were dead...could be a dead cell draining all the others. At the very least get them checked individually, not as a bank.
