What is a Mitsubishi Shogun V80 airbag control unit?
The Mitsubishi Shogun V80 airbag control unit is the central safety unit that activates all occupant restraint systems in the event of an accident. It monitors sensors, stores crash data, and ensures the proper functioning of all airbag modules in the vehicle, which is crucial for safety during Mitsubishi Shogun V80 airbag control unit repairs.
This electronic control unit (ECU) is permanently connected to the vehicle's sensors. It detects accident situations and, if necessary, deploys airbags and seatbelt systems to protect occupants.
Developed for the Mitsubishi Shogun/Pajero V80 (model years 2006 to 2018), it is precisely tailored to its safety architecture. It plays a critical role in the vehicle's passive safety.
The module also stores crash data and relevant error codes. It can often be reset or repaired after an accident, making a complete replacement unnecessary.
Why is the Mitsubishi Shogun V80 airbag control unit defective?
A Mitsubishi Shogun V80 airbag control unit typically fails because it stores crash data after an accident, requiring a reset, or due to internal circuit errors that prevent proper function. Communication problems in the CAN bus or EEPROM errors can also cause failure, necessitating a Mitsubishi Shogun V80 airbag control unit repair.
The most common cause of a defect is the storage of collision data after an impact. This information blocks the system and prevents the airbags from deploying again.
Internal electronic defects, such as errors in the ignition circuits or the memory module (EEPROM/ROM/RAM), can also occur. Such damage directly affects the control unit's logic.
Problems with CAN bus communication often lead to errors because the control unit cannot receive data from sensors or other systems. Loose or damaged connectors are also a possible cause of failure.
Common error codes for Mitsubishi Shogun V80 airbag control unit repair
When repairing a Mitsubishi Shogun V80 airbag control unit, specific error codes are crucial for diagnosing the exact cause of a malfunction. These codes directly indicate problems within the control unit, from internal circuits to communication failures, and enable targeted troubleshooting.
- B1000 → Control unit communication error → The airbag control unit has a communication error.
- B1400 → Driver side airbag (1st ignition circuit) short circuit → Short circuit in the ignition circuit of the driver airbag.
- B1496 → SRS-ECU EEPROM memory error → Problem with the internal memory of the airbag control unit.
- B1499 → Collision decision error → The airbag control unit cannot make a correct collision decision.
- B1509 → Wrong SRS-ECU control unit detected → An incompatible or incorrectly coded control unit was detected.
- B1548 → CAN bus communication impossible → The control unit cannot communicate via the CAN bus.
What part numbers are available for the Mitsubishi Shogun V80 airbag control unit repair?
For a successful Mitsubishi Shogun V80 airbag control unit repair, correct OEM part numbers are essential to ensure compatibility and functionality of the replacement part. These include primary Mitsubishi numbers as well as compatible supplier and replacement part numbers, enabling safe rebuilding of the airbag system.
The primary original Mitsubishi OEM part numbers are MR587864 and MR584416. Both are listed directly by Mitsubishi for the Shogun V80 and verified in official catalogs.
The OEM suppliers supply the numbers 8651A049 from Autoliv and 5WK43127 from Bosch. These are 1:1 compatible and often offer a more cost-effective repair alternative.
A compatible spare part number from Continental is 7L0 959 655 B. This part is often recommended for repairs, but should be checked for accurate functionality before installation.
What should I keep in mind when repairing a Mitsubishi Shogun V80 airbag control unit?
When repairing the Mitsubishi Shogun V80 airbag control unit, it is crucial to strictly adhere to safety regulations and involve qualified specialists. Restoring functionality after an accident or failure often requires specialized reset services and the use of precisely fitting parts to ensure complete system integrity.
For a reliable repair, always choose the original Mitsubishi part numbers MR587864 or MR584416. High-quality OEM suppliers like Bosch or Autoliv are also a safe choice.
A common aspect of the repair is resetting the control unit after an accident, as it stores crash data. Specialized services can restore the module to its original state.
Installing the airbag control unit, typically located under the dashboard, requires specialist expertise. Ensure correct connections and a final diagnosis to rule out faults and restore the airbag system to full functionality.
