The videos below show you the best way to remove and replace your ABS actuator. It is very important that you use the SAME EXACT part number as your old one to avoid any issues. You can find them used on eBay or junkyard. I was getting code C1111 NISSAN – ABS Pump Motor. I used an ABS code reader to get the codes.

I picked up a working used ABS actuator from a friend for $100 bucks. It took me about 2 1/2 hours to get the job done. I removed the windshield wipers and the plastic/metal window cowl. This provided better access. Make sure you use a 10MM Flare Wrench to avoid stripping any of the lines. It not a very difficult job. In my opinion, the most time consuming part was having to re-bleed all the brakes again.

My Symptoms:

  • ABS Light came on
  • Trouble Code: C1111 NISSAN – ABS Pump Motor
  • ABS Actuator stayed on after the car is off for a few minutes
  • ABS was activating under normal regular driving

This is what it looks like when you remove the Window Cowl.

And there is goes.

Notes (From Member alchemist.zim):

  1. Find someone with an ABS scanner, and get ALL ABS CODES. There is no point in replacing just the pump if any of your sensors are bad as well
  2. If you do think you need to replace the ABS pump relay make sure you get the correct part number which can be found on the top of the part.
  3. A brand new one from Nissan is gonna run you $1000+. Junkyard prices start at $100 on eBay. If you decide to get a used part make sure it comes with a warranty.
  4. Have plenty of time to devote to the actual repair work. Its gonna take a minimum of 4 hours to do
  5. Unless you plan on dropping the engine, your gonna have to remove the intake manifold. The ABS pump is located on the passenger side firewall, and there is virtually no room to work in there
  6. Take pictures of where all of the lines, and sensors go. Everything becomes a blur when your all done, but you have 1 line loose, and you don’t know where it goes.
  7. BE EXTRA CAREFUL WITH ALL HARD LINES NEAR THE PUMP. You may think they are sturdy, but they really aren’t meant to be moved to much. If something breaks you in for a bad time

ABS Fuse (In the event the ABS Actuator is draining your battery and you cannot fix it right away, this is the fuse you need to remove)

As I’ve stated, before this my ABS pump would stay on as long as the fuse was in place. I removed the ABS fuse located next to the battery to prevent the pump from draining my battery.

!!!WARNING!!! This fuse also controls you power locks, windows, sunroof, trunk lock and turn signals from what I tell. It is a red combination fuse with 3 different fuses in it, with a clear plastic cover on top.
