What is an Infiniti Hybrid QX60h airbag control unit?
The Infiniti Hybrid QX60h airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It precisely monitors sensors, stores important crash data, and ensures the immediate and proper operation of all airbag modules and seatbelt pretensioners in the vehicle to provide optimal occupant protection.
This critical component continuously analyzes vehicle data to detect collisions. It is essential for the safety and functionality of the entire passive protection system in the Infiniti Hybrid QX60h.
The control unit communicates with other vehicle systems via the CAN bus and is responsible for the airbag system's self-diagnosis. Errors are reliably stored in the internal memory and can be read out.
Why is the Infiniti Hybrid QX60h airbag control unit defective?
An Infiniti Hybrid QX60h airbag control unit can malfunction because it stores crash data after an accident, requiring a module replacement, or due to internal electronic defects. Common causes include overvoltage, short circuits, or age-related component failures that impair its function and necessitate an Infiniti Hybrid QX60h airbag control unit repair.
Because crash data is permanently stored in the module after an accident, the control unit often needs to be replaced or reset. Otherwise, this data prevents the airbag system from reactivating.
Electrical problems such as short circuits, overvoltage, or undervoltage can also damage the internal circuitry. This leads to malfunctions or complete system failure.
Age-related wear and tear on electronic components or internal memory errors are also common causes of failure. In such cases, a professional Infiniti Hybrid QX60h airbag control unit repair is essential to restore driving safety.
Common error codes for Infiniti Hybrid QX60h airbag control unit repair
During an Infiniti Hybrid QX60h airbag control unit repair, specific error codes in the diagnostic tool indicate problems directly related to the control unit. These codes indicate communication problems, internal memory errors, or voltage problems with the airbag module itself.
- **B1000** → **Control unit communication error** → Cause: No communication with the vehicle network, often due to hardware defect or cable break.
- **B1020** → **Internal memory error in the control unit** → Cause: Defect in the EEPROM/Flash memory, requires repair or replacement of the module.
- **B1234** → **Short circuit in the airbag control unit** → Cause: Internal circuit problems or component failure in the control unit.
- **B1100** → **Voltage problem in the airbag control unit** → Cause: Undervoltage or overvoltage at the ECU input, leading to malfunctions.
What part numbers are available for the Infiniti Hybrid QX60h airbag control unit repair?
For a successful Infiniti Hybrid QX60h airbag control unit repair, knowing the exact OEM part numbers is crucial to ensure compatibility. There are two 100% verified original numbers that serve as interchangeable airbag control units for the Infiniti QX60h.
The main part number from Infiniti is 98820-9NB0A, which identifies the original SRS Airbag Control Module for the QX60h. This is directly verified for the vehicle model from approximately 2015 onward.
Another identical OEM supplier number is 0285012283 from Bosch. This Bosch number is the direct equivalent of the Infiniti part number 98820-9NB0A and is also considered a genuine part for the airbag control unit.
It's important to note these specific numbers, as other part numbers in circulation refer to individual airbag modules (such as driver or curtain airbags) and not to the central control unit. Correct assignment is essential for safety.
