Airbag control unit with part number P68148037AB

What does the airbag control unit P68148037AB do?

At Jeep the airbag control unit P68148037AB is the unit that controls the restraint system (SRS). Via the crash sensors it measures how strong an impact is, determines which airbags and seatbelt pretensioners are triggered, and checks the system continuously. After an accident it stores crash data and locks itself.

The control works while the vehicle is driving, without anyone noticing it. If it detects a fault, it reports this to the airbag warning light in the instrument cluster.

Anyone who reads the part number P68148037AB from the unit has in front of them the unit on which the triggering and warning of the system depend.

Why does the control unit P68148037AB fail?

The main reason is crash data from an accident in which no airbag fired; a standard diagnostic tool does not remove it. Also possible are aged electronics, cold solder joints, moisture and corrosion on plug connectors, and voltage spikes. Airbag24 erases the crash data during the repair.

The crash data goes back to an event that the unit classed as an accident. That no airbag fired is irrelevant to this, and the memory remains nonetheless.

There are also causes related to the condition of the unit. Electronic components age, solder joints on the circuit board can be cold, and moisture attacks plug connectors.

A third area is the power supply. Voltage spikes, for example from a weak battery or a jump start, can harm the electronics.

How can you tell that the P68148037AB is defective?

A defect is indicated by the warning light in the instrument cluster, an error message, a diagnostic tool without connection and a fault memory that cannot be cleared. If the control unit is affected, the airbags may fail to trigger in an emergency.

The signs in detail:

• Airbag warning light on permanently or intermittently
• Error message in the instrument cluster
• Diagnostic tool does not find the control unit
• Fault memory cannot be cleared

If any of these displays appear, a prompt check is worthwhile.
