hi.. randomly the antilock braking light shows up in my VZ.. not all the time tho..

is this due to the pads being sort of low.? also could it be time to change the brake fluid etc...

or will cleaning the sensors at the brakes fix this?

it has the abs unit in the front right of the engine bay and is 4 wheel abs

cheers

No, no and no.

Next time the light comes on, pull over and leave the ignition on.

Roll the drivers seat all the way forwards.

Under the carpet next to the sill is the ABS ECU. Lift the carpet flap so you can see the flashing LED.

Count the flashes.

I'll see if I can find the list of fault codes.

Mine was the same, but ever since I lowered it, the light hasn't come on again. I can only guess there's a damaged wheel speed sensor and lowering it has closed up the broken wire or something. ABS works fine anyway.

Bust out the multimeter and check the resistance of both front sensors. They should be around 1000 - 1200 Ohms. Unplug it at the first connector from the sensor and measure there. I think you'll find the RF sensor will be open circuit.

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
