Is anyone having a problem with the noisy as hell self check from the ABS pump. When the car gets up to 15 mph the pump self checks, and boy of boy is it noisy as hell. They tell me it is a known issue, and Nissan intends to do nothing about it.
For a new vehicle to make that kind of noise in my book is unacceptable.
And what moron decided to soild mount a pump to the body w/o isolating it.
If Nissan isnt going to do anything about this, I need to find a cure.
Prefer to get enough people to complain to Nissan about it.

Its not real loud, reminds me of something wrapped around the half shaft, slapping the body or frame.When it does self check it last maybe 10-15 seconds. to me regardless there should not be any noise/vibration from the pump. Had many other cars/trucks w ABS and never had this problem.

From the FSM:
ABS Function INFOID:0000000004307257
• The Anti-Lock Brake System detects wheel revolution while braking and improves handling stability during
sudden braking by electrically preventing wheel lockup. Maneuverability is also improved for avoiding obstacles during emergency braking.
• If the electrical system malfunctions, the Fail-Safe function is activated, the ABS becomes inoperative and
the ABS warning lamp turns on.
• The electrical system can be diagnosed using CONSULT-III.
• During ABS operation, the brake pedal may vibrate lightly and a mechanical noise may be heard. This is
normal.
• Just after starting the vehicle, the brake pedal may vibrate or motor operating noises may be heard from the
engine compartment. This is normal due to the self check operation.

They should have doen a much better job isolating the noise. Not acceptable in a 16-18k car.:smilejap:
