Hesitation after bumpy road turns

[steveberger]

It's snowing today in Connecticut. I have been following this post and decided today, probably being the last snow day this season, would be a good time to try and make my RL hesitate. Sorry guys couldn't do it. Floored it from a dead stop on a slushy wet road and it accelerated straight and true. The VSA light did flash a bit, but there was no hesitation. Accellerated around a wide left turn and a sharp bumpy right turn - again the VSA light and the smallest bit of understeer, but no hesitation.

In the past I have felt some power reduction and slight loss of speed if I hit an especially slippery spot or large puddle with only one side of the vehicle, but I would not call it "engine hesitation". I think this is the proper response of the the VSA.

ACRidge, sounds like your Uncles RL acts more like mine. Hope you can get this fixed. The engine shouldn't "hesitate" or stall

Please watch video of Honda engineer trying to go up slick muddy hill, and then listen to his explanation. ALL Ridgelines can and will cut throttle depending on wheel spin conditions. ALL RIDGELINES can and will experience throttle cutout. All you have to do is get on slick hill (sorry Iowa and plains states) stop, and give it the gas. Your throttle will cutout and you WILL turn VSA off if you want to get to the top of the hill. Pea or loose gravels on level roads under hard acceleration from a stop will give you the same result. I'm sorry if you can't re-create this condition but every ridgeline truck can and will do it. It's the way they designed it.

Here is an explanation by Kodiak:
Answers to VSA questions:

1. The course that was shown in the video was pounded on by over 60 runs prior to the TOV demonstration. The course was torn up and in terrible shape. Due to the extensive use, the top surface was covered in loose sand and dirt. The VSA system limits wheel slip, which under certain conditions prevents you from maintaining forward momentum; this was one of those examples.
2. Disengaging VSA does not put the vehicle in front wheel drive. The VTM-4 system is automatic and is always active transferring power to the rear axle when appropriate. It is also predictive rather than reactive like the competitive systems. It always launches in 4wd. Disengaging VSA simply allows you to control wheel slip with the throttle rather than the computer over-riding your inputs. It generally always better to leave the system in automatic mode until it intervenes excessively due to the road conditions. All the previous runs during the day were conducted in full auto mode. Unfortunately, when this demonstration was done, the course condition had excessively deteriorated.
3. The vehicle was also placed in VTM-4 lock which sends the maximum amount of torque to the rear axle. In order for this to be engaged, the vehicle must be placed in 1st or 2nd gear and driven at speed under 15mph. During the second run both the VSA was shot off, and VTM-4 lock was engaged to allow maximum possible torque to be transmitted to the rear wheels. This was an excessively steep hill which is difficult to understand from the video (28 degrees). As for speed, in general, speed is not your friend when off-roading. It makes for great videos, but is not good for control or safety.
