MAN Electronically Controlled Air Suspension List
ECAS stands for Electronically Controlled Air Suspension in MAN trucks. The fault codes are generated when a problem is detected by the system’s sensors, actuators, or control modules.
To address ECAS fault codes, technicians typically perform troubleshooting steps that may involve inspecting connections, checking air pressure levels, verifying sensor functionality, or conducting tests using diagnostic equipment.
