ABS light on - checking the fuse

5th June 2018, 20:33

Hey guys, my abs light came on, so the first thing I wanted to do was to check the fuse to see if it is the cause of the problem.
Problem is, the original fuse - 30A - is 32v. All I can get my hands on are 12v fuses.
Changed the fuse to a new 12v one, light did not dissapear. I inspected the fuse I just installed, it wasn't blown. So either it is not a problem that it is 12v, and I need to disconnect the battery for a moment to check if the light dissapears or it's not the fuse.
Is it worth taking the time to disconnect the battery? Or would the light dissapear just from changing a faulty fuse?
Didnt actually check the original fuse. I put it back instead of the new 12v one for the time being, as I have a hard time not losing stuff and I figured it might be useful for reference later

Don't laugh I don't have a gauge lying around where Im at now and the old fuse is not transparent.

you need to plug it in to see where the fault is.
you could jet wash the wheels,around the sensors.see if that clears the fault.

Thank you mate, didn't think about this, wheels are kinda dirty. Still kinda new to all these things, trying to figure out.
That would be another thing that costs nothing to check.
Where are the sensors located? Behind the brake disc somewhere?

There is probably just a sensor that has failed.

You can test this with a multimeter. each sensor should be between 900 and 1200 ohms across the terminals. All the sensors should read about the same.

It is not a fuse problem. when the fuse blows, the "handbrake" light AND the ABS light come on at the same time.

i also have a c2 that as a dodgy front abs wheel bearing.
when the light comes on i just use a bit of brake cleaner and tissue and clean
round the inside of the magnetic bearing where the drive shaft goes in .one day i might get round to putting a new bearing in.

Been to my mechanic yesterday and had him scan the error, says there is a break in front left sensor. Error couldn't be erased, does that mean that it's the sensor for sure? I guess it might also be wiring and not the sensor itself. Gonna see a car electrician soon.

Yep you need a new sensor mate.

try cleaning the inner bearing

This is a different system to a C2. These have a toothed ring on the driveshaft.

If it was dirty/rusty it would give an intermittent signal, not 0 signal.

Saxos have a toothed ring or c2's?
Anyways, do all the kinds of saxos have the same abs in the front? Or do these with VTR/S front discs have something else?
Are there two separate braking force regulators for front/back?
Need to finally change my rear beam to one with discs to match the engine. Might not even make a big difference with the way im driving the car most often, but having drums in the back with a 1.6 fucks with my mind somehow

. Apart from the handbrake cable, the master cylinder would be on it's way out too in that case right?
Had to change the drums some time ago because tire change place twisted treads on them, turns out they are a different kind of drums for euro 1.4 vts setup.
Anyways, UK 8V models and 1.4s didnt have ABS, right? Seems like citroen dropped VTR range for the mk2 in the continental saxos and all these sporty ones were marked VTS.

Saxos have toothed rings on the driveshaft for the ABS sensor.

There is one variable brake force valve on the rear axle as standard. The system still works without it.

ABS was always an available option on nearly all spec of Saxo and 106 in the UK.

Drums ABS setup doesn't have a brake force regulator. It has difference slave cylinders in the drums which give less pressure. I think they're larger diameter too, non ABS drums are 180mm and ABS drums are 200mm.

That's all I know

Is changing a sensor a parking lot + jack job?
Car is already at a shop, but might try to do it myself if another one fails.
My father is an electrician (not a car one at all thought) so he might be able to help me with wiring if something else goes to shit.

14th June 2018, 19:25

you just need to take the wheel off and maybe the wheel arch liner to get to the other end of the sensor lead.
then just plug a new one in.

It's fairly straight forward as long as the bolts aren't too rusty.

Jack up, wheel off, there's 2 10mm bolts to undo.

The sensor sits in a metal block, sometimes they're really hard to remove. I had to smash mine out and then remove the old sensor case.

Slot in the new sensor with plenty grease and re-fit.

The plug is on the bulkhead at the chassis leg "inside" the engine bay. You'll get it from underneath. There's no need to remove the wheel arch liner.

Thanks mate, seems simple indeed. Need to start tinkering with it if something breaks again so I can actually learn stuff. Also because dealing with repair shops gets annoying there if you own a saxo of that kind. I've been asked a couple times already if it is a xsara, or c3. For some reason they don't have this problem with regular saxos. Is it the VT bodykit?
Only managed to find one guy who understands what Im telling him, but his shop is kinda far away and I have to wait long to fix simple stuff. 60% of cars there are oldish VAG's so there you go I guess.
Had a bit more luck with rally workshops, they know what it is right away, but every time I call them they try to sell me a roll cage

. Honest to god its that ridiculous.
On the other hand, if anything ever breaks on it its cheap to fix and relatively simple.
Does anyone use VTRs/VTS as an everyday car in the UK anymore?

Yes people use them regularly here as every day cars. Less and less though as they get old and rusty

Europe has different specs.

UK specs = VTR 1.6 8v, VTS 1.6 16v, Furio 1.4 8v. Any other spec is either a 1.1 or a 1.4 8v.

Euro specs you can get VTS and VTR with just about any engine.
Peugeot were the same. In Europe you can get a 1.1 litre that is identical to a GTi (except the engine obviously).

VTR and VTS is basically a body kit and different suspension. That's it.

So maybe your garage is just idiots hahaha!
