INSPECTION PROCEDURE
CAUTION:
Before inspecting the high-voltage system, take safety precautions to prevent electrical shocks, such as wearing insulated gloves and removing the service plug grip. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work Click here.
Tech Tips
At least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
When disposing of an HV battery, make sure to return it through an authorized collection agent who is capable of handling it safely. If the HV battery is returned via the manufacturer specified route, it will be returned properly and in a safe manner by an authorized collection agent.
Note
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Click here.
Tech Tips
After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
Turn the power switch on (IG) and wait for 10 seconds or more.
PROCEDURE
CHECK DTC OUTPUT (HYBRID CONTROL)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
Read output DTCs.
| Result | Proceed to |
|---|---|
| P0AFC-123 or P0A95-123 is not output. | A |
| P0AFC-123 or P0A95-123 is also output. | B |
Turn the power switch off.

CHECK CONNECTOR CONNECTION CONDITION
CAUTION:
Be sure to wear insulated gloves.
Check that the service plug grip is not installed.
Note
After removing the service plug grip, do not turn the power switch on (READY), unless instructed by the repair manual because this may cause a malfunction.

RECONFIRM DTC OUTPUT (HYBRID CONTROL)
Connect the GTS to the DLC3.
Turn the power switch on (IG).
Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.
Read output DTCs.
| Result | Proceed to |
|---|---|
| Hybrid battery voltage sensor circuit DTCs for this diagnostic procedure are not output | A |
| Hybrid battery voltage sensor circuit DTCs for this diagnostic procedure are output | B |
Note
Turning the power switch on (IG) with the service grip removed causes other DTCs to be stored. Clear the DTCs after performing this inspection.
