The main fix is to do a reset procedure, and if this does not work, an OBDII scan tool will be needed to read error codes.
An advanced OBDII scan tool will be needed to read ABS codes, with many scanners not having these features.
If you do not have a scan tool that can read these advanced codes, auto parts stores will usually do a scan for free.
Be sure to check all fuses before doing any fixes.
What is an ESP BAS Light on a Chrysler 300?
ESP BAS light stands for “Electronic Stability Program and Brake Assist Program.”
It was created to give a driver better control when driving in adverse conditions.
For example, if you are driving while it is raining, the ESP system will give better traction and control.
The ESP light should flash briefly when it is working and then go off.
If the light stays on continuously, there is a problem with the ESP system.
Causes and Fixes ESP BAS Light Chrysler 300
- (SAS) Steering Angle Sensor
Often it just needs to be realigned, but sometimes it is bad and needs to be replaced.
Before replacing it, do the reset procedure first, as it often clears the light.
The reset procedure is a series of turning the steering wheel all the way left then right and centering it.
If it does not work, the steering wheel sensor may be bad. An OBDII scan tool will be needed to see what the error code is.
The sensor is located in what is called a steering wheel spiral cable clock.
How To Reset the ESP/BAS Switch: Steering Angle Reset Procedure Chrysler 300
- Insert the key and turn the engine ON.
- Turn the steering wheel all the way to the left.
- Turn the steering wheel all the way to the right.
- Turn the steering wheel all the way to the left again.
- Center the steering wheel (Wheels Straight).
- Turn the engine off, then restart.
- Drive, and the light should go off after you get into second gear.
If a sensor goes bad, it will cause an issue, and the ESP BAS light will come on.
An OBDII scan tool with advanced features to read OBDII error codes will be needed and often give one of the following errors when there is a bad wheel speed sensor.
Common Chrysler 300 Wheel Speed Sensor OBDII Error Codes
- C1035 Right Rear Wheel Speed Sensor
- C1020 Left Rear Wheel Speed Sensor
- C1015 Right Front Wheel Speed Sensor Circuit
- C100A Left Front Wheel Speed Sensor Circuit
- C1032 Right Rear Wheel Speed
For example, if a C1035 error is given, there is a problem with the Rear Wheel Speed Sensor.
Most often, the sensor will need to be replaced when this error is given.

Other Possible Causes ESP BAS Light Chrysler 300
Wiring can also be a cause and should be examined to see if a bad connection or loose wire is causing the error.
Other components in the system that may cause an issue are the brake switch, rotor, and brake pad.
While not common, a low tire may also cause a problem, although this is likely rare.
There are several causes and fixes for an ESP BAS light on a Chrysler 300.
The first step is to try the steering angle reset procedure to see if the switch just needs to be realigned.
If this does not work, an OBDII scan tool with the advanced options to read ABS errors will be needed to scan the onboard computer for codes.
The codes given will point to the problems, which can then be fixed.
If you do not have an OBDII scan tool that can read the codes, most auto parts stores will do a scan for free.
Of course, be sure to call around first to make sure.
