Inspection Procedure

WARNING:

Before inspecting the high-voltage system, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. 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. Refer to PRECAUTION [12/2014 - ] .
HINT:

Waiting for 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 ignition 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. Refer to PRECAUTION [12/2014 - 05/2015] .

HINT:

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
1. Connect the Techstream to the DLC3.
2. Turn the ignition switch to ON (IG).
3. Enter the following menus: Powertrain / Hybrid Control / Active Test / Driving the Battery Cooling Fan.
4. Select fan mode 6 and operate the battery cooling blower assembly.
Operation of the battery cooling blower can be confirmed by checking if air is sucked into the air intake port of the intake duct.
