What is a Toyota Tank Custom Airbag Control Unit?
The Toyota Tank Custom Airbag Control Unit is your vehicle's central safety unit, processing accident-relevant data from sensors to precisely deploy the airbags and seatbelt pretensioners in the event of a collision. It also stores important crash information, ensuring effective occupant safety in an emergency.
This control unit contains complex electronic circuits for signal processing and transmission. It is crucial for the quick and correct activation of all restraint systems in the vehicle.
Modern airbag control units also regularly perform self-tests to check their functionality and detect any errors at an early stage.
Why is the Toyota Tank Custom airbag control unit defective?
A Toyota Tank Custom airbag control unit can be defective because it stores crash data after an accident and is thus locked, or because internal electronics have been damaged by aging, moisture, or overvoltage. These defects lead to failure or activation of the warning light.
Failures are often caused by short circuits in the connected wiring harnesses or sensor lines. Improper repair attempts or improperly performed welding on the vehicle can also damage the control unit.
A timely diagnosis at a specialized workshop is essential for restoring vehicle safety when a defective device is detected. Repairing the Toyota Tank Custom airbag control unit is often possible and more cost-effective than purchasing a new one.

- B1920 → Rear left airbag circuit short circuit → Circuit wiring error or internal control unit error.
- B1921 → Open circuit in the rear left airbag circuit → Defect in the cable, connector or internal error of the control unit.
- B1922 → Rear right airbag circuit short to ground → Ground fault in the circuit or control module output problem.
- B1923 → Short circuit to positive (12V) in the rear right airbag circuit → Voltage error in the circuit or defective control unit output.
- B1925 → Short circuit in the rear right airbag circuit (PIT airbag) → Fault in the wiring or in the control unit itself.
- B1926 → Open circuit in the rear right airbag circuit (P/T airbag) → Wire break, contact fault or internal control unit defect.
- B1927 → Short to ground in the rear right airbag (P/T airbag) circuit → Ground fault in the wiring harness or internal circuit problem.
- B1928 → Short circuit to positive (12V) in the rear right airbag circuit (P/T airbag) → Overvoltage or defective output stage of the control unit.
These error codes are specific to the airbag control unit and require precise analysis for successful repair. A qualified workshop can read these error codes and perform the appropriate Toyota Tank Custom airbag control unit repair.
