I've notice this a few times, but wanted to ask to see if its a problem or just normal. I have automatic.

When I get into the TL in the morning, put it in gear and start to accelerate down the street, I will feel a very short pulsation coming from the accelerator pedal. You will also hear a short hum or mechanical sound. That is the only time, but it usually happens upon getting into the car and driving away. Is this the ABS diagnostic/check or something that's making the short pulsation/noise?

 

no one has noticed this?....c'mon guys

 

My '01 CL-S did this every day I owned it. I think it is normal with the automatics for some reason. Sounds like a power steering groan or something like that, right (only not as loud)?

 

cycling on to provide pressure for system. should be same in stick cars, if that is what it is,

 

i have that sound every morning in all 3 legends that i have. still can't figure out what it is. sorta sounds like airplane landing gear or a mechanical buzzing noise.

 

It's the Anti Lock Brakes doing a self check. My 03 Type-S does it at 6 and 15 mph. It is totally normal...do not be alarmed!

 

I have it on my 04 TL also, and there is a thread on vtec.net on this.

03 accord owners have chimed in and said that it was discussed with them and it was found to be normal, ie, the ABS doing a self test.

My dealer has checked twice and found nothing, probably because what they are hearing is what they expect, the ABS unit.

I have droped it from my radar.
