Airbag control unit with part number GJ32-14D374-AC

What does the airbag control unit GJ32-14D374-AC do?

The airbag control unit GJ32-14D374-AC is the control unit of the restraint system (SRS) in Land Rover. It evaluates the crash sensors, decides within milliseconds in an accident on the triggering of airbags and seatbelt pretensioners, and monitors the system continuously.

A detected fault is shown by the unit via the airbag warning light in the instrument cluster.

After an accident it stores crash data and locks itself.

Why does the control unit GJ32-14D374-AC fail?

Most common cause: crash data stored after an accident, even without a triggered airbag. A standard diagnostic tool cannot delete it. Ageing, solder joints, moisture and voltage spikes also play a role.

The crash data stays in the unit until the repair. The other causes in detail:

• wear of the electronics
• faulty solder joints
• moisture and corrosion on the plugs
• voltage spikes once the battery is weak or a jump start is given

Which cause applies here only becomes clear from the fault memory readout.

How can you tell that the GJ32-14D374-AC is defective?

The airbag warning light in the instrument cluster stays on permanently or intermittently. In addition, the instrument cluster shows an error message, and a diagnostic tool cannot reach the control unit. The fault memory cannot be cleared, so the airbags and seatbelt pretensioners may not trigger in an emergency.

The light is the first warning that is noticed in everyday use.

The cause may lie in the control unit or in the wiring; only the readout shows which.
