Airbag control unit with part number P68148050AD

What does the airbag control unit P68148050AD do?

The airbag control unit P68148050AD coordinates the restraint system (SRS) of Dodge. The crash sensors deliver their measured values to the unit, which decides within a fraction of a second which airbags and seatbelt pretensioners trigger. In addition, it monitors the system continuously and reports faults via the airbag warning light.

After an accident the control unit stores crash data and locks itself. What it reports you see in the instrument cluster; it has no display of its own.

The function runs unobtrusively in the background, and that is exactly why its monitoring is so important.

Why does the control unit P68148050AD fail?

The most common cause is stored crash data, even without a triggered airbag; a normal diagnostic tool cannot remove them. Added to this are aged components, cold solder joints, corrosion on plug connections and voltage spikes.

• Aged electronic components
• Cold solder joints
• Moisture and corrosion on plug connections
• Voltage spikes, for example with a weak battery or a jump start

An accident without airbag triggering therefore does not mean that nothing is stored in the memory.

How can you tell that the P68148050AD is defective?

The airbag warning light in the instrument cluster lights up permanently or intermittently. In addition there is an error message, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared. Then airbags and seatbelt pretensioners may possibly not trigger in an emergency.

The warning light shows the finding visibly and calls for a check before further journeys.

For the same vehicles, we also repair control units with the part numbers 56054100AA, 56054100AB, 56054100AC, 56054100AD, 68029112AA, 68029112AB.

How does the repair of the P68148050AD work?
