ABS fault

[R dumolo]

Hi everyone

 

I'm new to this site, ive had my 350z fairlady for about 2 years and i now have the ABS and VDC lights appear on my dash when i brake fairly hard.

 

I've taken it to a garage they ran diagnostics and said it's coming up with brake switch, brake pressure sensor and main relay fault. He is unsure how to approach this. I hope some of you can shed some light on my situation.

 

Thanks in advance.

Brake light switch is the easiest to start with.

When mine went the brake lights would only light up dimly.

Cheap easy DIY fix.

If you can change a light bulb you can do it

Few easy fix to try....

1.) As Headphones stated, check the brake switch - You can easily get to it, its just behind the brake pedal. Before you buy a new one, try disconnect and reconnect it firmly. If this doesn't help, get some contact cleaner and reconnect. Finally, buy and replace with new switch.

2.) If no1, doesn't fix that, check all brake lighted up when pedal is pressed. If bulbs not working, you might want to check them (Assuming they are normal bulbs, there should be 2 filaments in it).

3.) Make sure brake fluid is topped up to max.

 

Not so easy + expensive fix

1.) ABS pump needs replacing. 2nd hand from Zmanalex is around £250 ish, then around £200 ish labour to replace + fluids.
