I recently began seeing the ESC stability light come on at first start in the morning on my 2014 Challenger. It doesn't go off until I turn off the engine and re-start the car, then it doesn't come back on until the next morning. Turning the wheels fully in either (or both) direction does not turn the light out, pushing the traction button on the dash makes no difference, nor does driving it any distance. The car drives normally whether the light is on or not. The only way to make the light go off is to turn the car off and back on, then it won't come on for the rest of the day, even after sitting for several hours while I'm at work. But the next morning the light is back on at first start...


Don't know if this is just a nuisance light (and chime) or if something is starting to fail (car has only 16,000 miles on it). If just a nuisance, how can I stop it? If some failure is imminent, what should I be looking for?


Thanks in advance for any help.

Where do I get the codes?
If you don't have access to a scanner, do this:

Get in the car, close the door. Perform the following steps fairly quickly (in less than 3 seconds) :

Turn key to ON
then back to ACC
then to ON
then back to ACC
then to ON

If there are any stored codes, they will appear immediately, in place of the odometer. For instance an "Intake Air Temperature Circuit High" error will set a code of P0113:

P= Powertrain
0= SAE
1= Fuel and Air Metering
1= (See Fault Codes)
3= (See Fault Codes)

Schematic of a DTC code:

DTC is made up of 5 digits.

The figure below demonstrates the composition of a DTC. With this information it is easier to troubleshoot a DTC without knowing the description of the code.

X X X X X

Digit 1: B-Body, C-Chassis, P-Powertrain, U-Network

Digit 2: 0-SAE, 1-MFG

Digit 3:
1-Fuel and Air Metering
2-Fuel and Air Metering (Injectory Circuit)
3-Ignition Systems or Misfire
4-Auxiliary Emission Controls
5-Vehicle Speed Control and Idle Control System (ETC)
6-Computer Output Circuit
7-Transmission
8-Transmission

Digits 4 and 5: Fault (00-99)

Checked the codes, the only one that comes up is: U0101. Quick update, the stability light (only) came on yesterday when I was leaving work - first time that happened. I turned the car off and restarted, but the light came back on. Decided to drive home, but after about a block it was still not shifting out of first gear. Stopped and shut off the car, restarted it, light went out, and drove (and shifted) normally all the way home. This morning, stability light was back on at first start, went off when I shut off and restarted the car, drove normally...

U0101 is a Network Error. It signals that any of the following three problems may exist:

Faulty Transmission Control Module (TCM)
TCM harness is open or shorted
TCM circuit poor electrical connection

See the following link for more details.

Seriously, I don't understand how the TCM code makes the stability light come on. What am I missing?

Now the stability light and the ABS light are constantly on. When I try to check the codes, it shows dashes for about 30 seconds then shows dOnE. Also, the cruise won't come on now. Any suggestions?

The key trick won't show abs/esp codes. Only powertrain codes. Cruise will not work untill esp is fixed. You need a code reader that will read abs codes.

Update: Now the ABS light and the stability light are both on all of the time. When I search codes, I get ----- for about 30 seconds, then the dashes change to: dOnE. I also noticed that when I start the car there are 2 separate lights with the squiggles - one says "Off"" and goes out when I push the stability button. The other is the one that has been lighting up, and is now always on.


Thanks again for any help.

Hi Jim,

Are you interested in having your Challenger diagnosed at your Dodge dealership?
