Hellraiser ( firstname.lastname@example.org) gurgled happily, sounding
much like they were saying :
Not normally, no.
I s'pose that Fiat might have put some wierd ABS system on that
incorporates a brake-light bulb failure warning, but... <shrug>
Still - for the amount of time it'll take to rule it out, it's got to be
worth a check.
Cheers all - thought I'd sorted it cos it went off yesterday, but came on
soon as I started moving, so I guess I got a dodgy wheel sensor. Any way to
find out which one, short of giving Fiat 30 folding for a diag check?
Basically the sensors are small magnets surrounded by a coil, so as the
toothed ABS sensor ring spins, a current is generated.
With a DVM, check each one for resistance. Dunno what the actual readings
should be for your car. They could be anything between 600 and 2000 ohms,
but obviously the two fronts should be the same, and the same for the rears.
Set the DVM for volts and spin the wheel. You should get a reading of 50-700
Check the contacts in the plug are clean, and also the sensor rings.
Excessive brake dust can also cause ABS faults to show. Metallic particles
can get stuck to the magnets in the sensors.
If all sensors check out, maybe it's time for a visit to the dealer as the
fault could possibly be in the ABS modulator.
Just a word of warning. Taking the wheels off may not help you much.
Normally the sensors come with a continuous lead and end plug, i.e. no plug
on the sensor end!
The plug/connector to the car witing loom is INBOARD of the vehicle. Trace
the wire from the sensor into the bodywork. If no connectors are found
enroute then the connecotr will be found just inside the car, normally
withing six inches of where the sensor cable enter the Bodywork. This will
almost always be in an expected dry area. Often one has to dig behind the
internal trim to find the connector.
Wow. Done nothing to this car for a fortnight (was gonna drop it in for a
diag when I got chance), hit a speedbump and the ABS light went out. Been
working fine ever since!
Who says speedbumps are bad :)
Me! Car passed it's MOT yesterday with 2 advisories (sp?).
Front shocker, and anti-rollbar bush split, drop link damage. You can
put is down to speed numps and potholes, both of which exist in large
quantities round where I live.
As an aside, anyone know why exactly Kwik-Fit aren't allowed to do the
front shockers on Bravas? (Not that I was going there, but wanted to
price it, so I could haggle with somewhere else).
Remove removes from address to remove anti-spam measures.
Presumably 'cos they might have to do some work to change them :) Avoid
Kwik Fit, they quoted me over 200 quid to sort out a duff brake hose on a
Punto, saying it would have caused the caliper to stick on (!), which would
have worn the pads and most likely the disks..... yeah right, 10 quid to
Fiat for a pipe and 20 mins work, sorted :) There's nothing unusual about
the shocks on a Bravo/a, go to someone with a clue :)
