Airbag control unit with part number 68358975AC

What does the airbag control unit 68358975AC do?

The airbag control unit 68358975AC controls the restraint system (SRS) for Chrysler. It evaluates the signals from the crash sensors, decides within milliseconds in an accident whether airbags and seatbelt pretensioners are triggered, and monitors the system continuously. It indicates faults via the airbag warning light, and after an accident it stores crash data and locks itself.

The crash data the unit records at that point is a log of the sensor readings around the impact.

Monitoring runs in the background for as long as the vehicle is supplied with power.

Why does the control unit 68358975AC fail?

The most common cause is stored crash data, even if no airbag has deployed; it cannot be erased with a standard diagnostic tool. Other causes may also apply to the control unit 68358975AC.

Other causes at a glance:

• aged electronic components
• cold solder joints
• moisture and corrosion at plug connections
• voltage spikes, for example from a weak battery or a jump start

Crash data remains in memory until it is deliberately erased.

How can you tell that the 68358975AC is defective?

A defect shows up as the airbag warning light in the instrument cluster lighting up permanently or intermittently, and as a fault message in the instrument cluster. The diagnostic tool cannot find the control unit 68358975AC, or the fault memory cannot be cleared. In this state, airbags and seatbelt pretensioners may not deploy in an emergency.

Typical signs are:

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

The warning light is a direct signal from the system. Have the fault memory read out rather than waiting for the light to go out.
