Observe that, even when the VSA icon is on, the probabilities are that there is nonetheless a measure of digital intervention at play as a result of absolutely disabling VSA is just achievable by performing an intricate “pedal dance”, which falls exterior the scope of this information.
That is not the essential warning gentle, although, as a result of there’s a warning gentle marked “VSA” or “VSA Off” subsequent to the activation gentle, and if this one switches on whereas driving, it implies that no stability- or traction-control help is out there on account of an issue in both the VSA module or elsewhere within the automobile’s management system.

Listed here are some steps to observe to assist decide the trigger and probably repair an illuminated VSA gentle on Honda Accord fashions:
- Test for unequal tire sizes: If there’s a distinction between the tire sizes as fitted to the automobile, it will ship contradictory wheel velocity alerts to the VSA controller, main it to consider that a number of of the wheels are slipping.

Nonetheless, time has proven that VCM additionally will increase oil consumption, resulting in fouled spark plugs and misfires. This downside impacts all V6 Accords with VCM however seems particularly more likely to set off VSA warnings on 2009 and 2010 mannequin 12 months automobiles. These misfires will immediate the engine’s management unit to register an emission management failure, which can disable the VSA consequently, whereas illuminating the VSA warning gentle in addition to the Test Engine gentle.
