1 Answers
97+15 is not a fault code, it indicates the exhaust brake valve is open and can be manually closed. Here are specific details about the exhaust brake valve: 1. Introduction: The exhaust brake valve is an auxiliary brake and a necessary supplement to the vehicle's service brake. It uses the engine as an air compressor to generate braking torque, thereby slowing the vehicle down. 2. Application: Generally installed in the exhaust pipe, it closes the valve when deceleration is needed to block the exhaust channel and achieve braking effect. It is mainly used in vehicles that operate in mining or mountainous areas or frequently drive in complex urban traffic conditions.
