- You can if it’s always lit and you don’t loss power. But make sure it is checked as soon as possible.
- You can’t if it’s flashing while you’re driving. Make sure you avoid heavy acceleration and high engine speed. Then ensure the vehicle is stopped whenever it’s safe to do so. Then you can restart your engine after about 2 minutes to reset the engine management system.
However, if you notice the light’s still flashing, then turn off the engine and contact your mechanic to check the engine soon to avoid further damaging of the catalytic converter or diesel particulate filter.
