Airbag control unit with part number P68046100AG

What does the airbag control unit P68046100AG do?

The airbag control unit P68046100AG coordinates the restraint system (SRS) of Jeep. It evaluates the signals from the crash sensors, determines in an accident which airbags and seatbelt pretensioners trigger, and checks the system continuously. It presents faults via the airbag warning light. After an accident it stores crash data and locks itself.

The test routines run while driving and at start-up. They are designed to detect faults.

Why does the control unit P68046100AG fail?

Crash data stored after an accident is the most common cause, even if no airbag has deployed. A standard diagnostic tool cannot clear it. Other causes are aged components, cold solder joints, moisture and corrosion, and voltage spikes.

Crash data does not necessarily come from an accident with airbag deployment. That is precisely why it is worth checking after an accident in which no airbag deployed.

Component ageing, cold solder joints and corrosion on connectors develop over a long time, whereas voltage spikes arise suddenly, for example with a weak battery or jump-starting.

How can you tell that the P68046100AG is defective?

The airbag warning light in the instrument cluster lights up constantly or only intermittently. In addition, these signs appear:

• Airbag warning light that lights up intermittently or constantly
• Fault message in the instrument cluster
• No connection between the diagnostic tool and the control unit
• Fault memory that cannot be cleared

In an emergency, airbags and seatbelt pretensioners may fail to deploy while the fault persists. That is why you should not overlook the light.

Only the fault memory shows which component is affected.

Which vehicles is the P68046100AG fitted in?

The corresponding vehicles are listed here:

• Jeep Wrangler JK (2007-2018)

Comparing the part number with the label of the removed unit only confirms that it is the right unit. Have the fault memory read out beforehand: only it clarifies whether the control unit is defective or whether a connector or cable is the cause.

For the same vehicles, we also repair control units with the part numbers 68398609AB, P68003421AB.

How does the repair of the P68046100AG work?

First have the fault memory read out and attach the log. Then disconnect the battery and only afterwards remove the control unit. Create the repair order online, then send the well-packed unit.

At Airbag24 the unit is inspected on the test bench, defective components are replaced, stored crash data is deleted and a function test is carried out. Processing usually takes 3–4 working days.

After that the unit goes back to you. Our repairs come with 2 years' statutory liability for defects. The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.

How does the control unit P68046100AG get to Airbag24?

You send the unit as a parcel or book a UPS collection for an extra charge. For the return journey after the repair, Airbag24 also uses UPS.

Put the printed repair order into the parcel and pack the control unit shockproof.
