HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P0A60-288, P0A60-290, P0A60-294, P0A60-501, P0A63-296, P0A63-298, P0A63-302, P0A63-502: Drive Motor "A" Phase V Current
P0A63-502 - Drive Motor "A" Phase W Current

DESCRIPTION

The MG ECU located in the inverter with converter assembly monitors the motor inverter current sensors. P0A60 and P0A63 indicate malfunctions in current sensors, and they do not indicate malfunctions in the high-voltage system.

HINT
The term "drive motor A" indicates MG2.





MONITOR DESCRIPTION

The power management control ECU (HV CPU) monitors the motor inverter current sensor. If the power management control ECU (HV CPU) detects a fault, it will illuminate the MIL and set a DTC.

CONFIRMATION DRIVING PATTERN





1. Connect the Techstream to the DLC3.

2. Turn the power switch on (IG) and turn the Techstream on.

3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

4. Turn the power switch off.

5. Turn the power switch on (READY) and turn the Techstream on.

6. With the vehicle stopped and park (P) selected, move the shift lever to N, wait for 10 seconds and then move the shift lever to D. [A]

NOTICE:
Do not leave the vehicle for an extended time with the shift lever in N.

7. Slowly accelerate from a stop (0 mph (0 km/h)) to 25 mph (40 km/h) several times while using different acceleration patterns. [B]

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

9. Check that permanent DTCs are cleared.

10. If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK DTC OUTPUT (HV)

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Enter the following menus: Powertrain / Hybrid Control / Trouble Codes.

(d) Check if DTCs are output.

Result:





(e) Turn the power switch off.

B -- GO TO DTC CHART (P0A78-202) P0A78
A -- Continue to next step.

2. CHECK CONNECTOR CONNECTION CONDITION (INVERTER WITH CONVERTER ASSEMBLY CONNECTOR) P0343

NG -- CONNECT SECURELY

OK -- REPLACE INVERTER WITH CONVERTER ASSEMBLY Components
