This happened to my 2002 A4 1.8T with 5 Speed:

1. Sounds foolish, but have you pressed the ESP button???

2. I had to take mine to a mechanic, the scanner showed a code (don't remember it), and a sensor had to be changed, wasn't an expensive fix. Both times that this happened I had gone over a bump at high speed.

The esp bas light is on my 2009 dodge 1500 and it won't start


An Electronic Stability Program (ESP)/Brake Assist System (BAS) indicator is standard equipment on all instrument clusters. The ESP/BAS indicator is serviced as a unit with the instrument cluster.
The ESP/BAS indicator gives an indication to the vehicle operator when the Electronic Stability Program (ESP)/Brake Assist System (BAS) has been activated. This indicator is controlled by a transistor on the instrument cluster circuit board based upon cluster programming and electronic messages received by the cluster from the Controller Antilock Brake (CAB) and the Transmission Control Module (TCM) over the Controller Area Network (CAN) data bus.
The ESP/BAS indicator Light Emitting Diode (LED) is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the LED will always be OFF when the ignition switch is in any position except ON or START. The LED only illuminates when it is provided a path to ground by the instrument cluster transistor. The instrument cluster will turn ON the ESP/BAS indicator for the following reasons:
  1. Bulb Test- Each time the ignition switch is turned to the ON position the ESP/BAS indicator is illuminated for about four seconds as a bulb test.
  2. ESP/BAS Indicator Lamp-On Message- Each time the cluster receives an electronic ESP/BAS indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been activated, the ESP/BAS indicator will be illuminated. The indicator remains illuminated until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  3. ESP Full Off Textual Message- Each time the cluster receives an electronic ESP Full OFF indicator lamp-ON message from the CAB indicating that the ESP/BAS system has been manually disabled, an ESP OFF textual message will appear within the cluster odometer display. The ESP OFF textual message remains displayed until the cluster receives a lamp-OFF message from the CAB, or until the ignition switch is turned to the OFF position, whichever occurs first.
  4. Actuator Test- Each time the cluster is put through the actuator test, the ESP/BAS indicator will be turned ON, then OFF again during the bulb check portion of the test to confirm the functionality of the LED and the cluster control circuitry.
The CAB continually monitors the ESP/BAS circuits and sensors to decide whether the system is in good operating condition and the proper outputs to the components of the system. The CAB then sends the proper lamp-ON or lamp-OFF message to the Electro Mechanical Instrument Cluster (EMIC) (also known as the Cab Compartment Node/CCN).
For proper diagnosis of the ESP/BAS system, the CAB, the TCM, the EMIC, the CAN data bus or the electronic communication related to the ESP/BAS indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.

Mercedes 2002 c180 classic abs and esp lights remain on dash is it electrical problem? or back disc pads need replacing


only an inspection can reveal which, have your brakes checked

  1. If the ESP light on a Mercedes Benz stays on, try holding the ESP button down for a few seconds. If holding ESP down for a few seconds doesn't reset the program, it's time to head to your local Mercedes dealership for a repair. More likely than not, there is some sort of error with the steering mechanism which causes the ESP light to remain on. You don't have to be alarmed but it's best to get it checked out as soon as you're able to. Most Mercedes have a four year, fifty thousand mile warranty which is, literally, bumper to bumper except for maintenance service. But if the ESP light stays on, this will almost certainly be covered.
  2. If your car goes into a spin and the ESP light does not come on, it's time to see that repair shop too. Your Mercedes electronic stability program is not working properly if the car does not take control when a spin is detected.

Esp driving


location not stated, or road conditions. nor if in 4low , nor if the ESP switch is off or on. Ask Suzuki for help (lol) or any ASE shop.

it's not magic, it can not give traction , if none.
on ice slow down. (esp can do that too. slow you,brake you and even
shift gears in the transmission)

are you in 4wd? or high 4Low, esp is inactive. (or limited)
read the operators guide. (if lost, get one now)
read the page on driving on ice.
chapters 5,6,7.
have you had any off these conditions , related to ESP, this a
is the ESP light acting wrong, or CEL check engine light running?
are all dash lamps (warning) showing correctly per the opr. guide?
ESP & ABS are vary complex, (not magic)


quote from the servise manual. (car battery dead or disconnected?)
ESP control module
When ESP control module is removed / installed, do
not use impact wrenches which generate shock or
impact to avoid damaging sensors in ESP control
module.
Note that Calibrate word here..!
When any of the following operation is done, calibrate
steering angle sensor, G sensor and master cylinder
pressure sensor (in ESP control module) referring to
"Sensor Calibration in Section 4F
- When battery or dome fuse is removed. (
a low battery or weak)
- When steering angle sensor is replaced.
- When ESP control module is removed.
- When yaw rate / G sensor assembly is removed.



read this, it covers this system well,

http://www.wkjeeps.com/wk_esp.htm

read page 7-2 here (the do not drive words)
http://www.autodealertools.com/quickQuote/manuals/2007/Grand%20Vitara.pdf

this car has no center differential. (read limits there of)
are you using chains on the tires?
oper guide page 4-6 , read that yet?

If the vehicle speed is greater thanapproximately 30 km/h (19 mph), the ESP systems (other than ABS) will turn
on automatically and the light will go out.
When the transfer switch (if equipped) is
turned to the "4L LOCK" position, the

ESP systems (other than ABS) will be canceled automatically. The light will come on and stay on.
• If the ESP systems operate continu-ously such as when driving on slippery roads, the traction control functions of the ESP systems may be canceled temporarily to avoid overheating the brake pads, and the light will come on. After a short period of time, the ESP.

(this latter cut out happens, with wild driving)

I havea 2009 tuscon sx. the ESP OFF light comes on occassionally affecting the gearbox & not allowing the car to get out of gear. the ESP OFF button on the dash doesn't do anything. We have taken it...


Whenever that ESP/ESC warning light comes on, there is a diagnostic code set (DTC). This code tells the technician which component in the system CAUSED the ESP/ESC control module to turn ON the warning light!

Did the technicians SCAN for any DTC's? Since the vehicle is a 2009, the service department is supposed to have Hyundai's GDS (Global Diagnostic System) available to do this. If they don't have this equipment, find a service department that DOES!

BAS/ ESP light on the dash bord stays on all time the car engine is running


The BAS stands for Brake Assist System, don't remember what ESP stands for.
But the first thing to do is make sure the brake lights go on when you hit the pedal.
If not, then replace the brake light switch above the pedal.
If that is not it, it could be many things, such as a bad lateral acceleration switch.

ABS and ESP lights on all the time. I bought Audi A4 B6 2004 only two months ago. It started in heavy rain.


The ESP system means the Electronic Stability Program. If the ESP & ABS lights on the dashboard permanently the ESP & ABS system is faulty. You must access the ESP & ABS Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car (placed in dashboard, under a plastic cover above the ashtray). Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP & ABS ECU, in other words reset the ESP & ABS system and turn off the warning lamp on dashboard.

Jetta beeps 3 times while ESP light is on


Probably one of the ESP sensors have faulty connection.These sensors measure the speed of the wheels ,if they are not connected then ESP cannot work.For safety reasons the system will not start up and gives you this error message.
