Airbag control unit with part number 68299155AF

What does the airbag control unit 68299155AF do?

The airbag control unit 68299155AF is the central control of the restraint system (SRS) for Jeep. It evaluates the signals from the crash sensors, determines within milliseconds in an accident which airbags and seatbelt pretensioners are triggered, and monitors the system constantly. If it detects a fault, it shows it via the airbag warning light.

In the background the unit continuously checks sensors, wiring and its own function. Faults are stored in the fault memory, which a diagnostic tool can read out.

After an accident the control unit stores crash data and locks itself.

Why does the control unit 68299155AF fail?

A failure of the 68299155AF most often has its cause in crash data from an accident, even if no airbag was triggered; a normal diagnostic tool cannot erase it. Also to be considered are aged electronics, cold solder joints, moisture and corrosion at plugs, and voltage spikes.

The first point weighs most heavily, because crash data stays stored in the unit. Airbag24 erases it during the repair.

The other causes arise independently of an accident: components age, solder joints can be cold, and moisture or corrosion attack plug connections. Voltage spikes also damage the electronics.

How can you tell that the 68299155AF is defective?

A defect in the 68299155AF first becomes visible through the airbag warning light in the instrument cluster, which lights up permanently or intermittently, accompanied by an error message in the instrument cluster. In addition there is no connection from the diagnostic tool and a fault memory that cannot be erased. In an emergency, airbags and seatbelt pretensioners may then fail to trigger.

The warning light is the most important sign of a fault in the system. Have it checked promptly and do not dismiss the light as trivial.

A fault memory that cannot be emptied even after an attempt to erase it also points to the need for an investigation.
