I have a 2004 maxima, I started the car now slip, vdc, brake & check engine light stays on. Any suggestions!

Quit guessing and have ABS codes read. Symptoms would be indicative of a bad wheel sensor which often fail with hub/CV failures.

Is VDC switch turned on? If not check brake fluid level

See if the following information helpful:
1. Keep an eye on the dashboard for the indicators marked "SLIP" and "VDC Off" which will tell you the status of the computerized handling system if handling isn't normal. "SLIP" will blink when VDC is operating. "VDC OFF" means the system is off. Turn the VDC system back on if the Nissan's handling is poor by pressing the "VDC Off" button until the light goes out.

2. Adjust your driving if "SLIP" comes on. "SLIP" means the road conditions may be slippery. The VDC aids in steering and stopping, but be careful, even if VDC is engaged.

3. Remove any aftermarket suspension parts like enhanced shock absorbers if the "VDC Off" light comes on and handling is bad. The VDC system is geared for stock equipment and tires only. Use winter tires or snow chains on snow-covered roads. VDC won't substitute for the correct winter equipment.

4. Don't drive on very inclined corners with high banks and leave the VDC switch on if the handling is poor with VDC on. The system can't operate properly in that environment. Disengage VDC, or avoid those kinds of roads.

I think a trip to the nissan dealer may be needed. The Slip and VDC sytem is tied into the anti-lock brake system. Could be as simple as a vacuum leak or a bad check valve at the brake booster, or the ABS system could be malfunctioning.

VDC this is vehicle dynamic control, It works with the ABS (anti lock brakes) steering angle sensor and Yaw rate sensor. When this light comes on. it is due to a check engine light that has detected a problem with the powertrain,or a ABS fault code,To find the reason a enhance scan tool that communicates with you car is needed

Drives with not the same power cause the ECM goes into limp mode, you need to have the ECM scanned for codes and problem rectified.

air trapped in system. get flush & fill from shop with evac/fill equipment

Check brake fluid level, add fluid from sealed container if needed.

Also check for leaking rear axle seals. Look for oil on the inside of rear wheels.

All three lights came on at the same time while I was driving last month. The dealer said it was the sensors. Had them replaced for about $750

I would take the car to almost any auto parts store and ask them to check the ODB II computer for codes and to reset the "Check engine light". Get the code that they tell you and it should go a long way to pointing you in the right direction to fixing this problem. It might also be that when you pumped the brakes that you somehow set a code in the computer from the ABS system and now that you have the brakes pumped up and working correctly resetting the Check engine light might fix your problem.

Good luck! Write back with any code you get and I'll see if I can help you figure out what the problem might be.
