My check engine light came on along with my abs and vsc lights

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Not the dreaded catalytic converter code! The check engine light, ABS, and VSC lights coming on together often indicate a related issue. The P0420 could be a aproblem with your catalytic converter or related components, which can affect engine performance. The brake switch codes and ABS modulator assembly codes indicate issues with your braking system, possibly affecting ABS and stability control functions. Start by addressing the brake switch and ABS modulator issues because they're safety related. Once those are resolved, re-evaluate if the P0420 persists, as it will require further attention. Please note that in some cases, vehicles will turn off VSC and cruise control until the check engine light issue is addressed. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
