HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P0A69-677,P0A69-683,P0A69-684,P0A69-688,P0A6C-678,P0A6C-685,P0A6C-686,P0A6C-689: Drive Motor "B" Phase V Current
P0A6C-689 - Drive Motor "B" Phase W Current

DESCRIPTION

The MG ECU monitors the inverter current sensor. These DTCs are for malfunctions in the sensor lines and not for malfunctions in the high-voltage lines.

HINT
The term "drive motor B" indicates MGR.





MONITOR DESCRIPTION

The power management control ECU (HV CPU) monitors the rear 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





- Connect the Techstream to the DLC3.

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

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

- Turn the power switch off.

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

- With the vehicle stopped and the shift lever in P, move the shift lever to N for 10 seconds and then move the shift lever back to D. [A]

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

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

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

- Check that permanent DTCs are cleared.

- 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 Hybrid Control System
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
