Been driving around last 2 weeks, all 3 lights started coming on and also getting a buzzing sound from ABA ACUATOR. I plugged in and got

Code 1109 and Low Battery voltage in unit

Code1111 Abs pump..


Im thinking about replacing thr acuator itself, this part is 2000 with the Stealership, Im gonna get off of EBAY...

Has anyone gone thru this???????

Any help appreciated

 

Does the abs pump run when the car is off? I had the same problem and replacing the relay fixed it for me. Part number is 47605-C9900.

 

ehonda:

yes the pump still runs for awhile after I pull the key out, I have to unplug the battery or it will drain it out.
did u ever get any codes?? I got c1111-pump

 

Check your brake fluid, but its prob just a sensor/relay. Highly doubt you need a pump, but if your ready to drop $2000, just get the ABS sensor/relay for $200 and see if that cures it.

 

Don't remember the code, I had the problem last year. Ejgold's advice is what I did, check fluid, cleaned the master cylinder, bleed brakes. Still had the problem, so I swapped the relay.

 

UPDATE:

went and purchased the RELAY and slapped it in.

so far so good, no more lights and no sound coming from the acuator..

thanks fellas for saving me $$$$$

 

Even I had the same problem for my 2006 G35 4 door sedan. I disconnected the ABS relay during the bad weather with piles of snow. I was getting whurring noise from my car and the battery was dead. So, I replaced my battery with a new one and disconnected the ABS.
However, today I went to Infiniti Service Center to fix the ABS. He quoted a huge price just to fix this ABS. Here is the estimate which he provided. ABS Relay - $400 and Labour.
So, could you please let me know how I can fix it for less?
