If you have a Honda Acura and the VSA light comes with a yellow exclamation (!) and triangle, this has to do with the driving stability.
There is a switch to turn on or off the VSA system; if it does not work, there is an internal error with the VSA computer module.
The system will come on when there is bad driving condition but maybe an error if it stays on all the time and the driving conditions are good.
For example, if it is raining, the system can come on to help the driver maintain control over the vehicle.
If the weather is nice and the road conditions good, the light should not stay on.
What is the VSA Light in a Honda Acura?
VSA stands for Vehicle Stability Assist and is a system to help the driver control the car in less than ideal conditions.
Most modern vehicles have built-in driving assist controls that help when the roads conditions are not good.
When operating normally, the light will come on temporarily to show it is working and go off.
The Honda Acura has a switch usually located on the left of the steering wheel that tunes off the VSA system.
If the switch does not work to turn off the light, it will need the VSA module to be reset and cleared.
There are many Honda OBDII scan tools available, but not all will have ABS built in to scan the VSA system modules.
For example, the FOXWELL NT630 Plus is one such OBDII scan tool the has ABS built-in and can read and clear the VSA error codes.
There are many more types of ABS-compatible scan tools units available.
If you do not have the money to purchase a scan tool with ABS compatibility, many automotive stores will do a scan and reset for free.
Causes and Fixes VSA Light Honda Acura
- Steering Angle Switch
- Wheel Speed Sensor
Modern cars commonly have a steering angle switch built into the steering wheel.
The switch relays information to the module, which the computer uses to maintain stability.
There is a reset procedure for the steering angle switch, which usually requires turning the wheel all the way to the left, then right, and back to the center.
In some cases, they can go bad and need to be replaced.
If one goes bad, one can be bought at an auto parts store or online at Amazon or eBay.
Each wheel has a speed sensor that relays information back to the computer on speed and driving conditions.
If a wheel sensor goes bad, the computer will get bad data and give an error.
Bad wiring or loose connections can cause many issues.
For example, a loose connection n a wheel speed sensor can cause the same error as a bad sensor.
If you have a Honda Acura and the VSA light comes on, it may be normal, depending on the driving conditions.
If the driving conditions are good and the light does not go off, there may be a problem in the system.
Be sure to see if the light goes off by pressing the VSA switch.
If the light does not go off, an OBDII scan tool with ABS built-in will be needed to scan for codes.
Most good scan tools can also clear and reset the light if needed.
