What is the ESP on/off button in the dodge caravan?

Only way to tell is have a scan tool hooked up an check the DTC'S - diagnostic trouble codes . Most auto part stores will check these for free . Could be a simple wiring problem ,or a sensor of some kind or a brake control module . Don't know with out knowing what codes are stored .

Computr issue..disconnect batt or pull plug onit for a min..see if it clears. Or git car scand by a pro not a dealr

take it to a mechanic! the drive train is failing

Hi there is a fault in the electronic stability program or the ABS you will need it pluged in to determine the exact cause. Regards Jim...

Could be ABS sensor which is in wheel bearing.You have to replaced bearing to fix the problem.

There should be a button labeled ESP next to the hazard switch.

(Page 343 of your owners manual)
This mode is entered by momentarily depressing the ESP
OFF switch (located in the center switch bank, next to the
hazard flasher switch).
When in Partial OFF mode, the TCS portion of
ESP, except for the "limited slip" feature described
in the TCS section, has been disabled
and the ESP/TCS Indicator Light will be illuminated.
All other stability features of the ESP function
normally. This mode is intended to be used if the vehicle
is in deep snow, sand or gravel conditions and more
wheel spin than ESP would normally allow is required to
gain traction. To turn ESP on again, momentarily depress
the ESP OFF switch. This will restore the normal ESP ON
mode of operation.

To turn traction control off in a Dodge Grand caravan, you press and hold the "ESP OFF" button that is to the right of the hazard light button. See pictures

What are the rpm's showing at idle. They should be around 750. The idle might be a little low. When you turn it uses more power because of the power steering pump. Let me know how it works out

You have to rent the tool from autozone about 60 dollars refundable. The tool will reset the caliper by turning it in, the front you can use a C-clamp. Be very careful to turn the caliper in the correct way. Inquire clockwise or counter clockwise at the counter of autozone or rental auto supply store.

Fisrt, I don't recommend you try to find and remedy this problem. The vehicle is under warranty and even if it not under warranty it is still the rental campanies resposability. I would call the rental company and tell them thier vehicle is malfunctioning and you need to take it to a Dodge dealer to get fixed as it is a great inconvienience for you.

It sounds like a fuse has blown, but, why did it blow? If you replace the fuse that has gone bad you may damage other components and they may want tyou to then pay for said damage since you are not a certified technician blah, blah, blah, and so on.

So to protect yourself and your money leave it up to them, even if they have to tow it 500 miles to get it repaired, that is thier responsability to you as thier customer.
