Airbag control unit with part number P68148034AD

What does the airbag control unit P68148034AD do?

The airbag control unit P68148034AD coordinates the restraint system (SRS) in Dodge. It evaluates the signals from the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners are triggered.

It also checks the system during operation and shows faults via the airbag warning light.

In an accident, the unit writes crash data to its memory and locks itself afterwards.

Why does the control unit P68148034AD fail?

The most common cause is stored crash data on the P68148034AD, even without a triggered airbag. Aged components, cold solder joints, moisture and corrosion, and voltage spikes come on top of this.

Crash data is not a fault in the usual sense but an entry in the unit that does not disappear with a standard diagnostic tool. Airbag24 removes it as part of the repair.

Other causes in brief:

• aged electronics
• cold solder joints
• moisture and corrosion on contacts
• voltage spikes from a weak battery or a jump start

How can you tell that the P68148034AD is defective?

A defect on the P68148034AD can be made visible by the airbag warning light, which stays on permanently or intermittently in the instrument cluster. In that case, airbags and seatbelt pretensioners may fail to deploy in an emergency.

Typical signs are:

• error message in the instrument cluster
• diagnostic tool does not find the control unit
• fault memory cannot be cleared

A single sign is already reason enough to have the unit checked.
