Caution / Notice / Hint
WARNING: This page is about a different car, the 2025 Toyota Corolla Cross, 2024 Toyota Corolla Cross, and 2023 Toyota Corolla Cross. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Refer to the precautions before inspecting high voltage circuit.
Refer to PRECAUTION [11/2022 - 12/2024] , or refer to PRECAUTION [12/2024 - ]
NOTE:
- After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.
Refer to BEFORE DISCONNECTING BATTERY [11/2022 - 11/2023] , or refer to BEFORE DISCONNECTING BATTERY [11/2023 - ]
- When disconnecting and reconnecting the auxiliary battery
HINT:
When disconnecting and reconnecting the auxiliary battery, there is an automatic learning function that completes learning when the respective system is used.
HINT:
- P0C76-00 may be output as a result of the malfunction indicated by the DTCs in table below.
- The chart above is listed in inspection order of priority.
- Check DTCs that are output at the same time by following the listed order. (The main cause of the malfunction can be determined without performing unnecessary inspections.)
