Toyota Carina E airbag control unit repair⁽¹⁾

What should be considered with Toyota Carina E airbag control units?

The Toyota Carina E airbag control unit evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If the system detects a fault, the airbag warning light on the dashboard comes on.

In the event of an accident, the control unit decides whether and which airbags are triggered. To do so, it activates the airbag firing circuits and records faults in the fault memory.

After an accident, the control unit stores crash data and locks itself. Airbag24 repairs the control unit of the customer's vehicle: we check the unit in our workshop in Berlin, erase the stored crash data and repair the unit if a defect is present.

Which Toyota Carina E generations are there?

The Toyota Carina E was built as the T190 series from 1992 to 1997. The internal designation T190 applies to the model during this production period.

The Carina E was developed specifically for the European market. For assigning a control unit, the series and the year of manufacture of the individual vehicle are therefore decisive.

• T190 (1992–1997) – series of the Carina E, developed for the European market

Which series your vehicle belongs to can be determined from its year of manufacture and the vehicle documents.

How do I identify my Toyota Carina E airbag control unit?

The part number determines the exact version of the control unit. Together with the year of manufacture and the equipment of your vehicle, the matching unit can be clearly identified.

The part number is usually printed on the unit itself. Note it down together with the year of manufacture of your vehicle before the control unit is removed.

Examples of possible fault codes are B1000 (internal fault in the control unit), B1800 (driver airbag firing circuit faulty) and U0151 (communication with the control unit lost). A fault code alone does not prove a defect in the control unit; only testing reveals the cause.

What airbag equipment does the Toyota Carina E have?

The airbag equipment of a Toyota Carina E depends on the trim level and the market. For the T190 series, a driver airbag in the steering wheel is known; other airbags should be checked against your vehicle's equipment list.

Whether a front passenger airbag, side or head airbags are fitted can vary from vehicle to vehicle. A general statement on this is not possible without an equipment list. The vehicle identification number (VIN) can help when checking the equipment.

The airbag system is safety-relevant, so work on it should only be carried out by specialist workshops. The repair at Airbag24 proceeds as follows:

• Have the fault memory read out so that the findings are established
• Have the battery disconnected and the control unit removed by a specialist workshop
• Create a repair order online
• Send the control unit to Airbag24

Processing usually takes 3–4 working days (checking, repairing, testing). Whether a defect is present and which repair is needed is only shown by the check after the unit arrives. The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is necessary.
