What does the airbag control unit LC3Z-14B321-B do?
The airbag control unit LC3Z-14B321-B is the switching centre of the restraint system (SRS) in Ford vehicles. It checks the signals of the crash sensors, determines in an accident which airbags and seatbelt pretensioners fire, and then locks itself.
In operation, the unit monitors all components and stores faults in memory. The airbag warning light in the instrument cluster informs you about faults.
Why does the control unit LC3Z-14B321-B fail?
The most common cause of the control unit LC3Z-14B321-B is crash data stored after an accident, even if no airbag has fired. A normal diagnostic tool cannot remove it; Airbag24 erases it during the repair.
Besides crash data, aged electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes can come into question. A weak battery or jump-starting can cause such voltage spikes.
How can you tell that the LC3Z-14B321-B is defective?
A defect in the LC3Z-14B321-B shows up as the airbag warning light in the instrument cluster lighting up permanently or intermittently. Error messages or connection problems with the diagnostic tool may also occur.
Typical signs are:
- The airbag warning light is on permanently or intermittently.
- An error message appears in the instrument cluster.
- The diagnostic tool receives no connection to the control unit.
- The fault memory cannot be cleared.
In an emergency, airbags and seatbelt pretensioners may not trigger with such a defect. Therefore, have the cause clarified promptly.
Which vehicles is the LC3Z-14B321-B fitted in?
The control unit LC3Z-14B321-B is fitted in these vehicles: Ford F-Series Super Duty 4 P558 (2017-2022).

Compare the number on the label of the removed unit with this page. This only shows that it is the correct unit, nothing more. Have the fault memory read out beforehand, because only this result shows whether the control unit itself is defective or whether a plug or cable is the cause.
