What made you look at the YAW sensor feeds? 

Process of elimination. 
 

I worked my way through wiring diagram, then tested power supplies

The code was showing as yaw sensor failure which I doubted. 
 

Then I actually used chatgpt to work through my theory Got it to research what others had done. 
 

folks seemed to get to yaw sensor, discover the lack of 12v and just piggy back 12v from the obd. 
 

but I used the wiring diagrams to track to abs module. Checked it for output which it hadn’t and then replaced it. 
 

chatgpt was amazing as it confirmed everything I’d researched myself prior but took 3 seconds rather than hours I took trawling only forums and posts. 
 

Well 4 months later I got to the bottom of this. 
 

YAW sensor was not receiving 12v via the grey wire (orange in the US)

 checked all fuses and connections. 
 

then checked the ABS module under the steering column and pin 34 sends the 12v to the YAW sensor. 
 

no 12v outta the module so I replaced the module with another used one and away it went lol. 
 

now to rebuild the interior

This happened to my 350 before and I know it sounds silly but try a new set of pads - fixed it for me at least

thanks will do, will have a look, I know the rear pads and handbrake shoes will need sorting. front pads look like they have some life left

Sounds like the car thinks one wheel is continually slipping.  I'd stick a multimeter on the wheel speed sensors, first check they have battery voltage, then disconnect and check resistance across them.  If its not the same left to right or resistance is zero, its a fault with the wheel speed sensor / wiring.  If its not at battery voltage to begin with its a fault upstream, maybe in the ABS module.

thank you input and thoughts, if it was the ABS module would the ABS light also not be on?

Hi,every track day my ecu esp and tcs lights come on. Think gets overheated. Peddle dance or Ob gets rid of ecu and usually esp/tcs goes off after cooled down. At Cadwell my car started bogging and I struggled to get off. After cooled down it was ok. Think esp was so overheated it kept slowing the engine. Had a track day crash and afterwards,after a short distance the skid light would flicker and then both lights came full on   Steering wheel not central. Had car tracked and no lights since. Perhaps your stressful use has damaged a sensor. Suspect if my esp had been working i wouldn’t have crashed. Poor excuse. Good luck 

Jeff

thanks for the info, peddle dance hasn't shifted the esp and tcs lights and 3 months later they still come on with each drive.

in terms of overheating, im guessing you mean wheel speed sensors or perhaps yaw sensors? 

beginning to create a list of things to swap out/replace lol 

Ok I’ll have a look at that thanks. It’s not showing anything on basic obd code reader. Going to link it to a more sophisticated one asap. 
 

battery disconnect 12hrs didn’t do anything or the ecu pedal dance. 
 

all fuses seem ok. 
 

brakes where proper proper hot by end

could brake disc/pad/rear shoe issues cause a tcs and esp light but not abs?

Need help! 
 

Was at a Trackday yesterday and at end of the day when I started the car again to go home the esp and tsc lights came on and won’t go off. The ABS light isn’t on and throwing no codes with basic code reader. 

Tsc was enabled all day and working fine right until car was turned off, I’ve watched GoPro footage and the slip light was popping on and off coming out of bends etc. 

Fluids all ok
Brake light switch seems ok as rear brake lights come on when pedal pressed. 
 

Any ideas? Pedal dance for ecu reset didn’t sort it and battery out overnight didn’t fix it either. 

Any ideas??

Thanks

Car show looks sweet and Z33 flying the flag proudly for you still 👌 big plans coming up next then

yes I’m flip flopping between air for practicality and visual impact or FI for the banter and extra power the zed needs imo 

few updates recently 

New set of tires for the summer also re-tinted the drivers and passenger side windows a light smoked tint.

recently at Dubshed which is the largest car show in Northern Ireland, few photos below

Past the 7yr mark with it now... toying with either looking at air-ride as I've recently moved to countryside with some terrible large bumps/holes etc or finally chatting to H-dev and going FI

Comments welcome as always 

Where is best place to watch ?

Nothing new to report with the 350z. Serviced at start of the summer and running well. Will be treated to tires next summer I think and it’s getting to enjoy last few sunny days before being sorned for winter. 
 

jobs for winter 

dye the headliner black

rear indicator bulbs to silvertec

few more photos from various meets this summer 

as always thanks for reading 

Was snapped leaving cars n coffee other evening

7yrs in and still love this thing

Quick update here

last month I changed over the pcv valve. No visible damage/clogging etc but I’m sure it was the original one so no harm changing it

another cosmetic change was removing the old badly corroded wheel nuts and replacing them with Tarmac Sportz titanium ones

nice n light and also tie in with the titanium exhaust lol

some photos of before and afters

bear in mind the old wheel nuts where less than 3yr old and not really driven in salt and winter etc

Yeah I did Donegal last year haha! New rears on 😅

aw awesome. The zeds are still a pretty rare beast here in Northern Ireland and even more so in the south. 
 

you will be a bright yellow zed in a sea of is200, twincams (ae86’s to rest of the world) and diesel vags. If you are about Belfast I’ll keep an eye out for your car lol. I’ve my zed out most days in the summer

Awesome job on the headlights! Love the car! I am driving my Zed to Ireland for Donegal rally in a couple of weeks! Can't wait!

Have you been to the Donegal rally before??

bring spare tires 😂 

thanks yeah super pleased with headlights. Have them also booked in to be lacquered 

am I right in thinking for a rev-up, its just transfer over the ballasts/seals and away you go?

Impressed with the headlights. Nice work. Did you just leave the dispersion pieces out of the reassembly yeah?

Yup that’s exactly what I did. Then added silvertec indicator bulbs 

What a job….

For a long time the headlights had been really bothering me on the zed. Typically Japanese yellowing but also I could see a clear tab inside the light that helps disperse light had also went yellow causing the entire unit to look poorly. It really aged the car in my opinion

So to take the headlights out, the bumper needs to come off, which involves taking out approximately 1000 10mm bolts.

Also to access around 1/2 the 10mm bolts both wheels and arch liners needed to come out too.

Then headlights come out and whilst also removing approx 3mm of flesh from each knuckle

Then headlights into oven for 7minutes at 100 degrees and then split. All to remove the yellowing tab.

Then reverse the process inc adding silvertec bulbs etc.

Polish to finish

very happy with the results and freshened front end up nicely. 
 

tomorrow I’m wrapping them in a clear uv film to keep them minty clear etc

Best she's ever looked!! That single exit must sound so fruity ☺️

its literally like thunder on cold start lol

Well show season is upon us. 
 

few photos I’ve taken recently in prep and also for show applications

Welp a fortnight in and im loving the recaros and Coolerworx. The shifter is ‘just’ on the side of useable fast road/track car. Any shorter/stiffer it wouldn’t work except on the track. Love how it’s looking though

Big morning today

The seats arrived 2 weeks ago and quickly got shipped to my house with the custom low slider rails. 

Anyone who has ever tried to fit a sliding rail option to a zed for an aftermarket seat always comments how difficult it is to get the seat low and sliding. 

Jdmdistro offered a custom low slider rail option from Japan and honeslty it was an oem bolt in style installation. 

Sits slightly lower than oem and slider is easy to use

but seriously if you are needing an aftermarket base mount option for rails then really consider the Jdmdistro guys. 
 

the fit of the rails could not have been more perfect inc all new hardware etc
 

also using the guide on here did the resistor mod for the seat airbags. No reset etc required so total win. 

had them professionally steam cleaned before installation and they came up like new

few photos

Updates coming thick n fast

fitted my new Coolerworx shifter kit today. 
 

WHAT A DIFFERENCE IT MAKES!!!!

went oem+ look rather than usual exposer mechanism etc

Nice one pal, which seat brackets you looking to use? 

jdmdistro who imported them mate offer a bespoke custom service where you can get ultra low sliders made for different cars. 
 

they are made in Japan with the seats 

welp 2 months turned into 4 months lol but they are finally here!!

Currently in a dpd van coming from jdmdistro to my door with custom low rails. seats are in perfect order in terms of cloth, need a decent clean, but no rips or tears, and I have a bolster kit sitting in my eBay basket if needed lol 

have also fitted a coolerworx shifter kit (will get photos this weekend) and what a difference that makes lol!! Proper clunk when you shift and it's very much shortened the throw. Only thing I a doing is relocation the hazard switch. 

I will be keeping the oem hazard switch in its usual spot, but due to clearance issues, you can't have the plug in the back. So I have got a DE hazard switch and plan to extend the loom and have that switch hidden somewhere so, I still have hazards if needed without a big hole in the dash or cutting anything up too badly
