Why is the VSA Light On In My Honda or Acura?

Has your Honda or Acura started displaying an illuminated VSA light in your gauge cluster? You’re not alone.

While it may be tempting to simply ignore those three glowing amber letters or triangle and hope it goes away, there are important reasons why the VSA light turned on. Keep reading to learn what causes the VSA light to turn on, whether you can continue driving, and the simple steps to reset it.

What is VSA in a Honda?
Throughout the years, various automotive manufacturers have coined their own unique names for stability control systems of their design. From this principle, VSA was born.

VSA stands for Vehicle Stability Assist, which serves as Honda’s stability control system of choice. This title also extends to various Acura models, as Acura serves as an extension of the Honda brand. Other car manufacturers have similar systems under different names including AdvaceTrac, ESP BAS, or simply ESP (Electronic Stability Control).

Generally speaking, stability control systems of any type, when engaged, prevent a vehicle from entering a hazardous skid, in one of several different ways. Most commonly, selective wheel-end specific braking is implemented to prevent the initiation of a skid.

Additionally, many newer stability control systems now utilize corrective steering and throttle engagement to bring a vehicle out of a skid that has already begun.

VSA System Indicator vs VSA Activation Indicator

When speaking on the subject of VSA-related lights, it is important to discuss the differences between a Honda’s VSA System Indicator, and VSA Activation Indicator.

The former of these two lights comes on, and remains on, to signify an issue with the VSA System itself, while the latter simply blinks to indicate that the VSA System is actively engaged, to mitigate a skid.

Is It Safe to Continue Driving With the VSA Light On?
While it is possible to continue driving, in light of an illuminated VSA or “Check VSA System” Indicator, doing so for extended periods of time is not advised.

This is due to the fact that an indicator of this type when illuminated, signifies that the system in question has been disabled. Because of that, the affected vehicle is operating without one of its safety critical systems engaged.

This is similar, in a way, to a vehicle’s ABS light, which signifies that an ABS-related fault has been logged, and as a result, the ABS function has been suspended. In fact, in almost every application, ABS and stability control systems operate hand-in-hand, with the former operating as an integral part of the latter.

In any event, the root cause of a vehicle’s VSA light should be thoroughly diagnosed and repaired at the first available opportunity. Doing so ensures that all safety systems are restored to full operability as promptly as possible.

If you do not feel comfortable diagnosing such issues yourself, an appointment should be scheduled with a trusted automotive service center as soon as possible.

What If the Check Engine Light is ALSO On?

In most cases, the sudden illumination of a vehicle’s VSA and check engine light indicates that an active VSA fault has been logged. In this case, the secondary check engine light has been used as a generic means to indicate that an active fault exists. By proxy, all VSA system functions are disabled until the underlying source of the fault itself has been repaired.

How to Reset the VSA Light
Throughout the years, Honda has employed a number of specific procedures to reset VSA lights on their vehicles. Therefore, it is always important to consult your vehicle’s owner’s manual before attempting to perform a reset of this type.

Nonetheless, the following steps can be followed to perform a generic VSA reset on numerous Honda vehicles, such as the Odyssey and Accord.

1. Start Vehicle – With the vehicle in question’s brake pedal in the released position, turn the ignition to the “on” position.
2. Observe Light – Next, carefully observe the vehicle’s ABS/VSA light, which should illuminate for approximately 2 seconds. This step is critical.
3. Press VSA Light – After the vehicle’s ABS light goes out, one should quickly press the dash-mounted VSA Off switch. Assuming that this has been done in quick enough succession, the VSA light in question should be reset.

Disabling VSA: Is It Ever Necessary?
Generally speaking, there is little reason to disable your Honda’s VSA function. After all, this is a safety-sensitive feature that is employed to ensure that a motorist’s well-being is always held paramount.

That being said, there is one key instance when disabling this system can prove necessary. Whenever you are marred in a rut, or otherwise stuck in less than favorable conditions, it might be necessary to disable this system, in a bid to maximize power to each respective wheel-end location.
