Airbag control unit with part number 68105432AH

What does the airbag control unit 68105432AH do?

The airbag control unit 68105432AH controls the restraint system (SRS) for Chrysler and Dodge. It evaluates the crash sensor signals and decides in an accident within milliseconds which airbags and seatbelt pretensioners are triggered.

The unit checks the entire system continuously. If it detects a fault, it shows this via the airbag warning light in the instrument cluster.

After an accident the control unit stores crash data and locks itself. For the system to deploy in an emergency, the control unit must function flawlessly.

Why does the control unit 68105432AH fail?

For the control unit 68105432AH, the most common cause is an accident after which crash data was stored, even if no airbag was triggered. Other causes that come into consideration are aged electronics, cold solder joints, moisture and corrosion, and voltage spikes.

Stored crash data cannot be deleted with an ordinary diagnostic tool. At Airbag24 it is deleted during the repair.

Further causes can be electronic components ageing over time, solder joints that have gone cold, and moisture or corrosion at plug connections. Voltage spikes arise, for example, with a weak battery or when jump-starting.

How can you tell that the 68105432AH is defective?

A fault on the control unit 68105432AH is indicated by the airbag warning light in the instrument cluster, which may light up permanently or intermittently. Added to this are an error message in the instrument cluster, no connection to the diagnostic tool, and a fault memory that cannot be cleared.

These signs can appear when the vehicle is switched on.

In an emergency, airbags and seatbelt pretensioners may not deploy. Do not leave the warning unattended.
