Airbag control unit with part number 77960-TR0-T014-M1

What does the airbag control unit 77960-TR0-T014-M1 do?

For Honda, the airbag control unit 77960-TR0-T014-M1 controls the restraint system (SRS): it processes the measurement data of the crash sensors, decides on airbags and seatbelt pretensioners in an accident within fractions of a second, and monitors the system continuously. After an accident it stores crash data and locks itself.

The unit reports faults via the airbag warning light in the instrument cluster. The driver sees the light, but the cause is not yet known from that alone.

Why does the control unit 77960-TR0-T014-M1 fail?

Stored crash data from an accident is the most common cause, even when no airbag has deployed. A standard diagnostic tool cannot erase it; during repair, Airbag24 erases it. Other possible causes include ageing electronics, cold solder joints, corrosion at plug connections and voltage spikes.

Crash data arise as soon as the unit registers an event, and they remain in memory until the repair clears them.

The other causes concern the components and their connections. A readout of the fault memory, together with an inspection, shows which finding is present.

How can you tell that the 77960-TR0-T014-M1 is defective?

The airbag warning light signals a defect when it stays on constantly or lights up intermittently. In an emergency, the airbags and seatbelt pretensioners may then fail to deploy.

• Airbag warning light in the instrument cluster stays on constantly
• Airbag warning light only flickers intermittently
• Fault message in the instrument cluster
• Diagnostic tool receives no connection to the control unit
• Fault memory cannot be cleared

Note how long the messages have been appearing before you send in the unit or visit a workshop.
