Re: Renault Modus-Braking Fault System
If 14.55v with car not running it's too high, but IF car IS running it's just on borderline but I would say acceptable
I was taught for alternators (this is before fancy electronics circa 1986-1988 lol) acceptable voltage charging rates are between 13.8v to 14.4v give or take +/-0.2 volts - obviously dropping when all electrics on (i.e heated rear windows/lights/blower) and at highest just after starting.
I'm sure it really is time to read any fault codes before replacing stuff willy nilly.
quite often I've had to clear codes 2-3 times until just the real error is left showing... also a fault sensor (i.e ABS) can have a knock on effect and may other items flag up too.
A good reasonable code reader is the icarsoft 907
