Airbag control unit with part number P68148052AB

What does the airbag control unit P68148052AB do?

The airbag control unit P68148052AB is the central control unit of the restraint system (SRS) for Dodge. It evaluates the signals from the crash sensors, decides on airbags and seatbelt pretensioners in an accident, and monitors the system continuously. After an accident it stores crash data and locks itself.

If the unit detects a fault, it reports it via the airbag warning light. The decision on triggering is made in a fraction of a second.

The lock ends only through the repair at Airbag24.

Why does the control unit P68148052AB fail?

The most common cause is crash data from an accident, even without an airbag being triggered; a normal diagnostic tool does not erase it. Further causes include:

• ageing in the electronics
• poorly soldered spots
• moisture and rust on plugs
• voltage spikes, for example from a weak battery or a jump start

Airbag24 removes the crash data as part of the repair. The list names the other causes without ranking them.

How can you tell that the P68148052AB is defective?

A fault becomes visible through the airbag warning light, which lights up continuously or intermittently, and also through an error message in the instrument cluster, a diagnostic tool without connection to the control unit, and a fault memory that cannot be cleared. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

• airbag warning lamp lights up continuously
• warning notice in the instrument cluster
• no connection established with the diagnostic tool
• fault memory remains after an attempt to clear it

If any of these signs appear, have the fault memory read.
