Volvo Bus B8l3: Engine Management System (ems)/enginecontrol Module (ecm) Software Update
Recall Summary Volvo is recalling 451 B8L3, B8R3, and B8RL3 buses because their engine management software has a defect that prevents the check engine light from alerting drivers when the Lambda sensor (which monitors emissions) fails. This means the vehicles could operate out of compliance with emissions regulations without the driver knowing. The fix involves installing updated software to the engine control module.
