Airbag control unit with part number P68148052AD

What does the airbag control unit P68148052AD do?

The airbag control unit P68148052AD controls the entire restraint system (SRS) at Dodge. From the crash sensor signals, a decision is made within milliseconds in a crash as to which airbags and seatbelt pretensioners fire. In addition, it checks the system continuously during operation.

Faults are indicated via the airbag warning light. After a crash, the unit stores crash data and locks itself.

The control unit is therefore the point where all safety functions come together.

Why does the control unit P68148052AD fail?

The most common cause is crash data that is stored after an accident, even without an airbag being triggered; a normal diagnostic tool cannot erase it. In addition, ageing electronics, cold solder joints, moisture and corrosion on plug connections, and voltage spikes come into consideration.

Crash data stays in the unit until Airbag24 erases it during the repair. An ordinary diagnostic tool cannot do that.

Ageing components, cold solder joints and damp or corroded contacts disrupt the electronics in different ways. Voltage spikes, for example from a weak battery or jump-starting, add to this.

How can you tell that the P68148052AD is defective?

The airbag warning light in the instrument cluster lights up permanently or at times. In addition, a fault message appears in the instrument cluster, the diagnostic tool receives no connection to the control unit, and the fault memory cannot be cleared.

In an emergency, the airbags and seatbelt pretensioners may then fail to trigger, and it is precisely these signs that point to this.

If you notice any of these signs, have the fault memory read out promptly.
