Computer problem
1991 Porsche 911 6 cyl Two Wheel Drive Automatic 60000 miles

my anti lock brake light and rear spoiler warrning light come on intermittently while I am driving.

But after the car sat for one month with a trickle charge all these issues disappeared.

Is it posilbe that if the battery charge is low that I will get these intermittent on and off of these warning lights? How can I verify this?

Hi there,

Thank you for the donation,

This could well be a low voltage problem, I would confirm that there are no fault codes, and keep the battery fully charged, if there is a problem the lights will re set regardless of battery charge.
