DTC SUMMARY

  1. MALFUNCTION DESCRIPTION

    These DTCs indicate the current sensor value is abnormal. The cause of this malfunction may be one of the following:

    • Internal inverter malfunction

    • Inverter with converter assembly internal circuit malfunction

  • Inverter low-voltage circuit malfunction

  • The connectors are not connected properly

DESCRIPTION

The MG ECU, which is built into the inverter with converter assembly, monitors the main and sub sensors of the rear motor inverter current sensor. DTCs P0BF6-683, P0BFA-685, P1C6F-688, P1C70-689, P33C1-684, P33C6-686, P33D8-677 and P33D9-678 indicate malfunctions in the current sensors, and do not indicate malfunctions in the high-voltage system.

Tip:

The term "drive motor B" indicates the rear motor (MGR).

DTC No.

CAUTION / NOTICE / HINT

CAUTION:

  • Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly, 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.

    Tip:

    Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.

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.

Tip:

After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.

  1. Turn the power switch on (IG) and wait for 5 seconds or more.

  2. Turn the power switch on (READY) with the shift lever in P and wait for 5 seconds or more.

  3. Move the shift lever to N and wait for 5 seconds or more.

  4. Depress the accelerator pedal of the vehicle with the engine stopped and the shift lever in P to start the engine.

  5. Drive the vehicle forward with the shift lever in D for 5 m or more.

  6. Drive the vehicle backward with the shift lever in R for 5 m or more.

PROCEDURE

  1. CHECK DTC OUTPUT (HYBRID CONTROL)

    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

    4. Check for DTCs.
