What you can do

1If you have a diagnostic tool: have the lower secondary actuator activated and check that it responds to the command
2Check that the damper can move freely and that nothing is blocking it
3Check the signal cable with a multimeter for an open circuit and a short circuit to supply voltage
4If the fault remains, have a workshop with diagnostic equipment check the lower secondary throttle unit
