How to pull ABS codes?
I did a search and for some reason, most of the threads seemed completely unrelated.
My ABS light came on this morning after driving about 2 miles. Turn off the car, the light is out when I restart but comes back on after driving a mile or so. I noticed the last restart, that just before the ABS light came on, my speedometer was reading 20 mph and I know I was going faster than that. When the ABS light came on, the speedometer returned to the actual speed I was going, which was 40 mph.
I just had the axle, hub and wheel bearing replaced on Monday and this problem started today (Thursday). I've driven about 200 miles since the work was done. Wet and cold today, so all I have done was look at the front wheel area to make sure the ABS sensor isn't just hanging down. Other than making sure the sensor bolt is tight, what else should I be looking at?

Did you replace the parts previously? If not, did you talk to your mechanic?
Sounds like a bad sensor. They typically damage the wiring/sensor when removing all the surrounding parts.
Might want to check resistance in the wiring. You have the ESM? Check page BR-62 for reference.

Found the problem...the shop didn't tighten the bolt for the ABS sensor. I figured I'd pull the sensor out, thinking maybe they got grease on it. Put the 12mm socket on the bolt and it wasn't even tight. Still removed the sensor to make sure it was clean. Took a lot more turns of the ratchet to tighten it back down than to remove it.

Anyways, if it was just a loose sensor than that was an easy fix.
You can read the ABS codes with other scan tools besides the Nissan Consult tool, just not with your regular code reader.

More than likely a Modis, Solus, etc high end diagnostic tool can read the codes. Most likely found in the higher end shops, not your typical mom and pop type places due to extreme cost.
But a CONSULT-II is easier to find, and is guaranteed to read them.
Actually, IIRC Cipher can read the ABS codes as well.

my abs light is on as well. just started happening on Tuesday...I was driving home from work sitting at a red light, and i felt the pulsation of the ABS engaging/disengaging FOLLOWED by the amber "ABS" light in my dash
(arrrrgh another damn problem with the max *sigh*)
So at this point i cut the car off, and start it back up....ABS light is OFF.......I then drive for two blocks and it comes back on
Today it goes out and I drive for like 75 miles without it coming on, now its back on and going on/off....
When i put the car in accessory mode, the ABS light stays on and i can hear the ABS disengaging/engaging as i go from Ignition off, to Ignition on
Would this be sensor related or would it be the ABS pump/actuator?
Since consult II is the next best thing and the ABS light is on, based on what im reading the best thing to do is to take it into the STEALERSHIP since i dont know any one local with a consult II

If you clearly saw that you need a diagnostic machine to check, as you said above, then why are you asking for a method that doesn't exist?

That may work for prior models, but the A33B FSM specifically states that they can only be pulled via a diagnostic scanner. No mention of grounding the OBD-II connector at all.

Just because it isn't in the manual, doesn't mean it doesn't exist!
It appears that either pin 7 or 9 is the magic one. Hmm.

*sighs*THANKS VQPOWER.Im sick of the Max right about now
I just dumped 3500 dollars into it to get the throttle body replaced, ECU, IACV, New Mirror/Painted, New Tires, and wheel hub/bearing
Im sick of it......im not putting another 2 grand into it..........
G35 here i come

Are you speaking from experience? Or....what?
Has anyone compared the wiring differences (if any) between the 5 and 5.5 gens ABS systems?
I'm just wondering if the only diffferences is in the FSM, with people following the original "ground pin 8" erronious information...so they just decided to take the self diagnosis out all together.

Figured I'd dig this up instead of creating a new thread...
I just replaced the right rear ABS sensor on my 2002 and the ABS light is still on, based on Scottwax's solution just tightening the bolt turned the light off. When I went to replace the sensor the bolt was so corroded that the head broke clean off, the new sensor took quite a bit of effort to even seat all the way so I figured not having the bolt would be fine as it doesn't seem like it will go anywhere...will this really not turn the light off?

Getting ABS codes thru ABS light
Now i have no idea what to do with the codes cuz they're not on the OBDII list I have....
#29
Hey VQPwr: I definitely got the ABS light to blink some codes in my 03 Max by grounding the #9 pin (top right on wider side of OBDII connect) to the #5 pin (count right 2 left on lower row starting directly under #9)
Now i have no idea what to do with the codes cuz they're not on the OBDII list I have....

The rear sensors are to be found on the rear door side of the axle with 1 bolt holding it in place, if you remove the rotor you'll see the reluctor that the sensor magnet picks up it's signal from. The fronts are located in the cv joint.
#36
Just a heads up to anyone pulling out an ABS sensor to inspect and clean, where corrosion is an issue (salted roads), if the retaining bolt head snaps don't try prying out the sensor without a good soaking in penetrating oil (I like Castle Thrust) and working it free; it's plastic and will snap. Once its soaked for a bit try light taps to break it free and it pulls straight out.

I had to replace my ABS sensor last winter. Got an OEM part from Advance Auto only to find out the connector wasn't right!!! What a pain, anyways ended up getting the part from the dealer and my TCS SLIP ABS lights all went off!
My local dealer checked the code without charging me and cut me a good deal on the ABS sensor so it worked out alright.

now what
so I pulled the code - it's 35 - rear left sensor open circuit.... that means the sensor is dead, right?
so I tried to loosen the bolt and I gave it a good soak of WD-40 and it still snapped (
now what - time to bring it to the shop?
thanks.
btw - mine is 5th gen and the 'grounding method' does work to pull the code.

An open circuit code means just that, the computer is not receiving any input from that sensor. This could mean a sensor failure, or a circuit failure (as it says right in the code description).
Follow the diagnostic procedure starting at BR-62.
Personally I would start off with making sure everything was plugged in and scoping the sensor, if that checked out then verifying circuit integrity from the LR up to the ABS control unit.

My rear right has been held in by friction for three years now, no issue.
