Selangor,Kuala Lumpur (KL) - Toyota Vios / Yaris 2018 Amplifier (Toyota 88650-0D820 / Denso MA277400-5052 - 5G)
29-Jan-2026
The Toyota Vios / Yaris 2018 Amplifier (88650-0D820 / Denso 277400-5052) is the updated Air Conditioning ECU for the facelifted third-generation models. It is a highly integrated control unit that manages modern HVAC functions like variable compressor cycling and digital climate interface communication.
- Toyota Part Number: 88650-0D820 (often marked with "5G")
- Denso Part Number: 277400-5052 / MA277400-5052
- Manufacturer: Denso (Genuine OEM)
- Voltage: 12V
- Vehicle Application:
- Toyota Vios 2018 (NCP150 / NCP151 facelift models)
- Toyota Yaris 2018 (NSP150 / NSP151 models)
Critical Technical Notes
- Compatibility: This unit is specific to the 2018 facelift and newer. It is notably different from the 2017-era amplifier (88650-0D770). Ensure you match the 88650-0D820 part number exactly, as incorrect versions may cause CAN-bus communication errors with the instrument cluster or climate panel.
- Failure Signs: Common symptoms of a failing AC ECU include the compressor failing to engage despite proper gas levels or the AC indicator light blinking.
