1411 – AL Flap Byp B restricted Limit 1
Cause
Corrective action
The range of rotation on homing
the bypass flap B side (M52.2)
has violated limit value 1. Flap
travel is marginally restricted.
1. Check smooth operation of the exhaust flap mechanism.
2. Contact Service.
1414 – AL Flap Egr A restricted Limit 2
Cause
Corrective action
The range of rotation on homing
the EGR shutoff flap A side
(M53.1) has violated limit value 2.
Flap travel is restricted.
1. Check smooth operation of the exhaust flap mechanism.
2. Contact Service.
1415 – AL Flap Egr B restricted Limit 2
Cause
Corrective action
The range of rotation on homing
the EGR shutoff flap B side
(M53.2) has violated limit value 2.
Flap travel is restricted.
1. Check smooth operation of the exhaust flap mechanism.
2. Contact Service.
1416 – AL Flap Byp A restricted Limit 2
Cause
Corrective action
The range of rotation on homing
the bypass flap A side (M52.1)

1420 – AL Flap Egr A blocked drive
Cause
Corrective action
The mechanism of the EGR
shutoff flap A side (M53.1) is
blocked.
1. Check smooth operation of the exhaust flap mechanism.
2. Contact Service.
1421 – AL Flap Egr B blocked drive
Cause
Corrective action
The mechanism of the EGR
shutoff flap B side (M53.2) is
blocked.
1. Check smooth operation of the exhaust flap mechanism.
2. Contact Service.
