VDC and slip light on!
 

Need more clarification about "all my tranny fluids changed".

Who did the fluid change, if it was anyone other than the Nissan or Infiniti dealership then EXACTLY what fluid did they use? Was it a drain and fill or was it a powerflush?

You had the service work performed at the Nissan or Infiniti dealership correct? And they used 100% OEM coil packs?

What was the original reason for replacing all 6 coil packs?

Of course they did...

For the future there is absolutely no reason to change a coil pack unless it malfunctions. It's a component that's good for 300k+ miles or more with no moving pieces but they eventually fail randomly.

As for the transmission issue I suspect an electrical malfunction, clean the battery terminals, both ends of the negative cable, the engine to chassis jumper on the timing cover, both of the grounds on top of the timing cover, one of them is the transmission ground and the most common point of 5AT malfunction.

Looks like you have something wrong with the front two wheel speed sensors, those are definitely causing slip and VDC lights to come on.

I'd check for physical damage to the wiring, you just had the front brakes done and I'm betting the mechanic that did the work either strained the harness OR just didn't plug everything back in correctly. The chances of them both going out at the same time are incredibly slim, start by inspecting the front right wheel speed sensor since it's throwing the most codes.

FIRST HOWEVER I'd have that battery tested to see if that abnormal battery voltage code is true or not, also clean up the battery cables really good because you can have a cascade of DTC's from a low battery.

The EVAP leak might be causing all those codes related to the catalytic converter, O2 sensors, I would definitely fix the EVAP system first before troubleshooting too deeply into the rest of those problems.

MM switch is probably fried, common problem and won't affect normal driveability but you won't be able to do manual gear selection on the transmission.

Knock sensor is probably the sub harness, common failure point, usually requires removal of the upper/lower plenum and the lower collecter intake. Some folks have managed to replace it with a coathook and a lot of patience... ymmv but it's worth looking up a youtube video so you can see what that entails.

This morning my VDC off, ABS and SLIP lights came on when I started the car. In the past, if I shut the car off and restarted they would go off. Today they stayed on. I was at work for 8 hours and when I left and started the car they came on and stayed on all the way home. Car seems to be running fine, no performance issues. Any idea what they might mean?
Thanks!!

Those lights mean the ECM or TCM has detected something outside the normal operating parameters. If you have the vehicle scanned with an OBD2 scanner you can retrieve the Diagnostic Trouble Codes (DTC) which will tell you the sensors that are detecting problems. From that point you can use the power of the internet to reference possible causes and begin the troubleshooting process.

VDC, Slip and other lights on
 

VDC, Slip, Brake and Battery lights came on tonight. Recently installed a catback exhaust last week then noticed the VDC and Slip lights came on after I left the shop. Was thinking of also getting an OBDC II scanner soon as well. Any idea how to rectify it? Possibly reset the ECU?
