Airbag control unit with part number 96442703

What does the airbag control unit 96442703 do?

The control unit 96442703 coordinates the restraint system (SRS) in vehicles of the make Chevrolet. It reads the crash sensors and decides within milliseconds in an accident which airbags and seatbelt pretensioners fire. It monitors the condition of the system continuously and displays faults via the airbag warning light.

The evaluation runs in the background, independently of driving. If the unit detects a deviation, it writes an entry to the fault memory, which is read out with a diagnostic tool.

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

Why does the control unit 96442703 fail?

The most common cause is crash data stored in the 96442703 after an accident, even when no airbag has fired; a normal diagnostic tool cannot remove it. Further possible causes are aged electronic components, cold solder joints, moisture and corrosion at plug connectors, and voltage spikes from a weak battery or a jump-start.

Crash data arises after an accident and stays in memory until someone deliberately erases it. The other causes lie in the electronics themselves. Aged components and cold solder joints impair the circuit, while moisture and corrosion disturb the contacts at the plug connectors.

Voltage spikes from a weak battery or a jump-start additionally load the unit.

How can you tell that the 96442703 is defective?

A defect in the 96442703 shows up as the airbag warning light in the instrument cluster staying on permanently or intermittently, and as a fault message in the instrument cluster. Add to that a missing connection to the diagnostic tool and a fault memory that cannot be cleared. In that case the airbags and seatbelt pretensioners may not deploy in an emergency.

The airbag warning light in the instrument cluster is the first signal you will notice. It stays on permanently or comes on only intermittently, and even brief phases count. A fault message appears in the instrument cluster at the same time.

A missing connection to the diagnostic tool and a fault memory that cannot be cleared are among the signs a workshop checks first. Therefore have the memory read out promptly.

Match the number on the label of the removed unit with this page. This only establishes that you have the right unit in front of you. Whether it is defective or a cable or plug is causing the fault is clarified only by the fault memory, so have it read out beforehand.

For the same vehicles, we also repair control units with the part numbers 5WY67040, 5WY67067-95160, 5WY67068-95160, 5WY67074, 96411996, 96442710.

How does the repair of the 96442703 work?

First have the fault memory read out and enclose the log before the battery is disconnected and the control unit 96442703 is removed. Afterwards create the repair order online and send the unit in. Airbag24 checks it, replaces defective components, erases the crash data and carries out a function test.

The log belongs with the repair order. Only once it is available do you disconnect the battery. Removal follows afterwards, and you then pack the unit securely.

At Airbag24 the checking, repairing and testing usually takes 3–4 working days. Your own unit is then returned to you.
