Airbag control unit with part number P68148040AA

What does the airbag control unit P68148040AA do?

The airbag control unit P68148040AA coordinates the restraint system (SRS) of Jeep. It checks the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners to trigger, and monitors the system continuously.

It indicates faults via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself. The repair lifts the lock.

Why does the control unit P68148040AA fail?

Stored crash data after an accident is the most common cause on the P68148040AA, even if no airbag has deployed. Further causes are ageing electronic components, cold solder joints, moisture and corrosion at plug connections, and voltage spikes from a weak battery or jump-starting.

A standard diagnostic tool cannot erase the crash data. Airbag24 erases them during the repair.

The other causes concern the electronics and their connections. Solder joints and plugs react sensitively to moisture, and ageing changes the behaviour of the components.

How can you tell that the P68148040AA is defective?

Defects on the P68148040AA show up as the airbag warning light in the instrument cluster lighting permanently or intermittently. In addition, fault messages appear, the diagnostic tool finds no connection, or the fault memory cannot be cleared.

• airbag warning light lights up permanently or intermittently
• fault message in the instrument cluster
• diagnostic tool receives no connection to the control unit
• fault memory cannot be cleared

With these signs, airbags and seatbelt pretensioners may possibly not deploy in an emergency. Therefore have the fault memory read out promptly.
