I figured I would ask here, cause most of us turbo guys have had our steering shaft off a couple times.

Is there a way to get the VDC light to flash codes and tell you what it is unhappy about?

My VDC light comes on the moment I start to roll away from a stop after just starting the engine. More than likely, somewhere along the way I messed up the calibration of the steering shaft and/or steering wheel, having had both out a couple times.

What is interesting, is that the VDC actually engages for a moment before it turns the light on. So its trying to do something.

Its clear to me that the steering position sensor is not properly calibrated right now, and when I pull away straight it thinks my steering wheel is turned, and then the VDC computer is seeing all 4 tires going the same speed so it thinks that I am slipping - since all 4 tires should not be the same speed if it thinks the car is turning.

Thats my best guess anyway.

So anyone know how to either check for VDC codes, or how to recalibrate the steering wheel position sensor? Maybe I am blind, but I cant find it in the service manual.

BTW, my car is running again Dyno numbers coming soon

 

Have you tried unplugging the Fcon and just let the stock ecu run the car and scan for codes?

 

i can scan for codes anyway, but i dont think the VDC troubles will show up in a standard OBDII scan, I would need a Consult

 

re-align the steering column, and reset the code...

 

I would love to... but how do you know when you have the steering angle sensor centered/aligned?

 

PEACE OF CAKE

FROM THE SUB MENU OF THE CONSULT II SELECT ABS ,THEN GO TO ECU INPUT AND YOU ARE GOING TO SEE YOUR CURRENT ST ANGEL SENSOR READING,IT SHOULD BE @ -2 +2 DIGRESS WHEN THE ST WHEEL IS STRAIGHT ,IF YOUR ST WHEEL IS OFF THEN YOU SHOULD PUT THE CAR ON THE ALIGNMENT MACHINE CENTER YOUR ST WHEEL WITH WATCHING YOUR ST ANGEL READING ,OR JUST REMOVE AND REPOSITION THE COUPLER .

OR... take up the center console and take out the VDC like real men do !!!!

 

The dealership was able to recalibrate mine when the same thing happened.

 

Sam, killer! Now how much is it to rent your Consult for a couple days?

theres another idea! maybe when i get the race logic.

 

that was my next plan, but i just hate going there when i know i can do it myself - and i also fear i will end up with a tech that has no idea how to do it.

 

just find a cool tech, me, personaly when i deal with a nissan service BS, i always meet the tech, tell him WHAT NEEDS TO BE DONE, in a nice way, as to save him hours of troubleshooting, then i tip a him 20 bucks for lunch, and say thank you.

its sucks you gotta kiss ***, but if you kill them with kindness you cant lose...
