Lexus ES: Hybrid/EV Battery Energy Control Module Monitoring Processor Watchdog / Safety MCU Failure (P060A47)
DESCRIPTION
The battery ECU assembly monitors its internal operation and will store these DTCs when it detects an internal malfunction.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P060A47 | Hybrid/EV Battery Energy Control Module Monitoring Processor Watchdog / Safety MCU Failure | ECU internal malfunction (1 trip detection logic) | Battery ECU assembly | Comes on | Master Warning Light: Comes on |
MONITOR DESCRIPTION
The battery ECU assembly monitors its internal operation. If the internal operation is malfunctioning, the battery ECU assembly illuminates the MIL and stores a DTC.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- 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 and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
-
With power switch on (IG) and wait for 30 seconds or more.[*1]
HINT:
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / HV Battery / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
