VDC stays on randomly
 

So I been having this issue for a long time with the Vehicle Dynamic Control, VDC light… Maybe if I can check the wheel sensors some how without taking them off or whatever ?

· Performed a ECU reset

· My brake fluid and brake pads are fine. I still have this issue.

· Tire pressure is good

· Fuses next to battery are good too ( VDC ABS and whatever the other one in there is )

· No other fault codes

· No other issues I can see

· I have Advanced LT is a plugin for Torque Pro

· My manuals https://rmccurdy.com/.scripts/downloaded/Q40/

· Past year I had to unscrew the break light switch to make it engage because I think when I was in a fender bender it got nocked down or something/somebody messed with it so when I lifted off the break it would think the break was still engaged and cruise control was not working. I fixed that. I did notice another switch next to the switch I fixed for cruise control not sure what that is for or if it needs to be adjusted.

· Its been doing it for a LONG time. I think even before I blew 3 fuses plugging in harness the wrong order when I made myself a AUX by hijacking the HD Radio input. https://www.myg37.com/forums/audio-v...rap-audio.html

· I don’t drive it hardly at all my wife drives and I work from home most the time 3-5 days a week

You may want to scan the ABS module for codes.
The least expensive way I know is OBD Fusion ($7) with the $14 Enhanced diagnostic add-on.
What is nice about this add-on, is it allows you to scan ALL the modules in the car AND if they have PIDs, you can view them in real time.

Here is a video on a G37 to show what is looks like

Herm looks like I did it right? Didn't see any fault codes. Or am I looking for ABS specific PIDs ?

Torque Pro with the Infiniti plug-ins ONLY show enhanced ECU PIDs/data, so that isn't going to help with ABS/VDC issues.

OBDFusion with the enhanced diagnostics can scan, clear and show LIVE data like individual wheel speeds and 40+ other ABS module related items.
