Vehicle Control History (RoB)

HINT:

If any of the conditions in the "Cause" column are met, data related to the Vehicle Control History item "Ready ON Prevention", "Hybrid/EV Battery Cooling Performance Decrement" or "Limit to Charge / Discharge Control Value by Hybrid/EV Battery" will be stored in the battery ECU assembly.
When the Vehicle Control History item "Ready ON Prevention" is stored, the vehicle condition will be as shown in the Symptom column.
There are unimplemented function codes depending on vehicle specification.

Vehicle Control History

FFD Group	Cord	Symptom	Cause	Vehicle Control History Data	Procedure
-	X0460	Hybrid/EV Battery Cooling Performance Decrement	History of poor HV battery cooling performance	Hybrid/EV Battery Temperature 1 to 6 Hybrid/EV Battery Cooling Fan Intake Air Temperature 1
03	X0540	Ready ON Prevention	Incorrect HV battery is installed (Power switch does not turn on (READY).)	Hybrid/EV Battery Determination Signal 1 Hybrid/EV Battery Determination Signal 2 "Hi" is displayed for both of these items when they are normal. If "Lo" is displayed for either item, the power switch cannot be turned on (READY) due to an incorrect HV supply stack sub-assembly having been installed.	Replace the HV supply stack sub-assembly with a correct one.
			Incorrect ECM is installed (Power switch does not turn on (READY).)	Number of Hybrid Battery Mismatch Judgment with Engine ECU "0" is displayed for this item when it is normal. If a value of "3" or higher is displayed for this item, the power switch cannot be turned on (READY) due to an incorrect ECM having been installed.	Check the part number and replace the ECM with a correct one.
			Battery diagnosis request was ignored (Power switch does not turn on (READY).)	Hybrid/EV Battery Check Status Light Request If a value of "6" or higher is displayed for this item and no other conditions are preventing the power switch from being turned on (READY), the power switch cannot be turned on (READY) due to Battery Diagnosis not being performed and the vehicle being driven for a certain amount of time after "Have Traction Battery Inspected" was displayed on the multi-information display.	Perform Battery Diagnosis using the Techstream.
			High voltage wire harness between HV supply stack sub-assemblies is disconnected (Power switch does not turn on (READY).)	High Voltage Line between Stack Engaged If "ON" is displayed for this item, the power switch cannot be turned on (READY) as the high voltage wire harness connecting 2 or more HV supply stack sub-assemblies is disconnected.	Inspect the high voltage wire harnesses connecting the HV supply stack sub-assemblies.
			Excessive engine cranking requests when HV battery cannot be used (Power switch does not turn on (READY).)	Number of Cranking when No Hybrid/EV Battery If a value higher than "15" is displayed for this item, the power switch cannot be turned on (READY) as engine cranking operation requests have exceeded a threshold when the HV battery could not be used.	Repair the malfunctions indicated by the output DTCs and clear the DTCs.
			Extremely low HV battery temperature judgment (Power switch does not turn on (READY).)	Hybrid/EV Battery Extremely Low Temperature Judgment If "ON" is displayed for this item, the power switch cannot be turned on (READY) as the temperature of the HV battery is extremely low. The values of "HV Battery Temperature 1 to 6" and " Cooling Fan Intake Air Temperature 1" can be used as a reference.	Wait for the HV battery temperature to increase.
			High HV battery cell voltage (The power switch is slow to turn on (READY).)	Hybrid/EV Battery Stack 1 Cell Maximum Voltage Hybrid/EV Battery Stack 2 Cell Maximum Voltage	Perform troubleshooting for any DTCs that are output.
			Low HV battery cell voltage (The power switch is slow to turn on (READY).)	Hybrid/EV Battery Stack 1 Cell Minimum Voltage Hybrid/EV Battery Stack 2 Cell Minimum Voltage	Perform troubleshooting for any DTCs that are output.
11	X0570	Limit to Charge / Discharge Control Value by Hybrid/EV Battery	History of HV battery charge/discharge being restricted If the temperature of the HV battery becomes approximately 40°C (104°F) or higher due to high ambient temperature, continuous driving under high load, clogged hybrid battery intake duct, etc., the HV battery current will be restricted. In this case the value of WIN/WOUT will decrease and the engine will stop and start less frequently.	WIN Control Limit Power WOUT Control Limit Power Hybrid/EV Battery Temperature 1 to 6 (Excessively high HV battery temperature: approximately 40°C (104°F) or higher) Hybrid/EV Battery Cooling Fan Intake Air Temperature 1 (If this value is high (approximately 38°C (100.4°F) or higher), due to high ambient temperature or high cabin temperature, the temperature of the HV battery may become high.)	Check for clogs in the hybrid battery intake duct. This Vehicle Control History item may be stored if the temperature of the HV battery became high due to certain conditions, such as if the ambient temperature was high or the vehicle was driven continuously under high load. Explain to the customer that this is not a malfunction. If this Vehicle Control History item is stored, perform the following inspections. Check the Vehicle Control History freeze frame data. Check for clogs in the hybrid battery intake duct. Inspect the HV battery cooling filter. Check the intake port of the HV battery cooling system for blockage, such as luggage, etc. After performing the above inspections, check the temperature of the HV battery in the Data List. If the temperature of the HV battery is high (approximately 40°C (104°F) or higher), stop the vehicle, turn the air conditioning system on (Temperature: Lo, Blower speed: Max) and perform the Active Test "Control the Hybrid/EV Battery Cooling Fan". Check that the temperature of the HV battery decreases. This Vehicle Control History item may be stored if the temperature of the HV battery became high due to certain conditions, such as if the ambient temperature was high, cabin temperature was high or the vehicle was driven continuously under high load (such as mountain driving or frequent acceleration/deceleration). Explain to the customer that this is not a malfunction.
