U0587 is a relatively uncommon code, often associated with newer vehicles that have complex electronic systems.
Moderate – While the vehicle may still be drivable, unresolved communication issues can lead to more serious problems.
Driving with unresolved communication errors can lead to unexpected vehicle behavior, which may be unsafe.
• Vehicle in ignition ON position
• Diagnostic tool connected to OBD-II port
The affected control module is usually located within the vehicle's dashboard or engine compartment.
