Title: METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: Hybrid System Indicator Malfunction; 2018 - 2024 MY Camry HV [07/2017 -        ]

Hybrid System Indicator Malfunction

DESCRIPTION

A hybrid system indicator has been included on this vehicle. In this circuit, the combination meter assembly receives the hybrid system indicator signal from the hybrid vehicle control ECU assembly via CAN communication. The combination meter assembly controls the operation of the hybrid system indicator according to the hybrid system indicator signal received from the hybrid vehicle control ECU assembly via CAN communication.

CAUTION / NOTICE / HINT

NOTICE:

  • When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
  • Before replacing the hybrid vehicle control ECU assembly, refer to Registration.
