Anti lock light is on. is it because ive not bleed the abs nipples in the boot when i bleed my brakes?

I thought that light came on when any of the fluid levels where low... what does it say in the owners handbook?

Dont know yet been to busy to look.but fluids not low nor is there any leaks.must have air in there but cant get rid.

MMmmmmm, if that's the case, then, just keep bleeding, bleeding, bleeding.... :)

this is a misconception, the low level switch is connected to the lamp on the dash (!) it is not even wired to the ABS control module.

 

i recently had ABS lamp issues and did a LOT of fault finding. a few things off the top of my head bring the lamp on:

 

alternator voltage below 6v

any wheel sensor U/S

pump failure

actuator failure

relay O/C

 

the first thing to do is finish bleeding your brakes until you have a good pedal again.

then take the car for a drive its something like over 20mph for 1min to let the ABS do a self test and check the signal back from each wheel.

if the light doesnt go out, remove the panel from beside the drivers side rear seat and you will find the ABS control module. there is a small 5mm clear window on it.

take the car for another drive as above and if the ABS light doesnt go off, pull over (dont turn off the engine) and look into the window on the module and you should see a red flashing LED. make sure your head is looking through it squarely and be patient, there is a big gap between codes and its easy to miss a flash.

 

these codes will tell you what the ABS isnt happy about R/F, L/F, R/R, R/F sensor, pump, actuator, voltage etc....

 

there is a full and very comprehensive test procedure in the manual which describes what pins to measure at the control module plug. my control module LED didnt flash and it turned out to be the module its self.

 

see how you get on.

 

cheers,

here is my thread if its any use.

the level switch goes to the (P) lamp, not the (!).

i think its a case of bleeding to get all the air out as the amount of pipe that was replaced was pfoberly 75% so until im happy with the breaks im not pulling anything else out cas thats going to confuse the issue. when i start the car up no light then by the time i get to the end of the road its on and im still not happy with the performance of the brakes.

ye im pretty sure thats what i said too.

Thanks for the info thou thats always handy to know
