L110F HYBRID VEHICLE CONTROL: HYBRID CONTROL SYSTEM: P3000-389: HV Battery Malfunction
DTC P3000-389 - HV Battery Malfunction
DESCRIPTION
The hybrid vehicle control ECU alerts the driver and performs fail-safe control based on error signals received from the battery smart unit.
This DTC is set if the HV battery is discharged excessively or the HV control system malfunctions.
HINT: If the HV battery voltage has dropped due to a malfunction in other components such as the inverter with converter assembly or the hybrid vehicle transmission assembly, recharging the HV battery will restore the voltage. If the HV battery voltage has dropped excessively after the vehicle was left for a long time, the HV battery will need to be replaced.
INSPECTION PROCEDURE
HINT:
- If the vehicle is stopped or parked with the shift lever in the N position for a long time, DTC P3000-389 may be set because the HV battery cannot be charged.
- When the engine cannot be started, DTC P3000-389 may be set because the HV battery cannot be charged.
PROCEDURE
1. CHECK DTC OUTPUT (HV)
(a) Connect the intelligent tester or Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Select the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / HV ECU / DTC INFO / CURRENT CODES.
(2) Techstream - Select: Powertrain / Hybrid Control / Trouble Codes.
(d) Check if DTCs are output.
Result:
HINT: If the HV battery voltage has dropped due to a malfunction in other components such as the inverter with converter assembly or the hybrid vehicle transmission assembly, recharge the HV battery and then repair the malfunctioning part.
B -- GO TO DTC CHART
A -- Continue to next step.
2. CHECK DTC OUTPUT (ENGINE CONTROL SYSTEM)
(a) Select the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS /ENHANCED OBDII / DTC INFO / CURRENT CODES.
(2) Techstream - Select: Powertrain / Engine and ECT / Trouble Codes.
(b) Check if DTCs are output.
Result:
B -- GO TO DTC CHART
A -- Continue to next step.
3. CHECK ENGINE START
(a) Turn the power switch on (READY).
(b) Check if the engine starts.
HINT: Depressing the accelerator pedal with the shift lever in the P position will cause the engine to start.
Result:
CAUTION: Do not turn the power switch on (READY) repeatedly after duplicating the problem symptom indicated by DTC P3000-389 and clearing the DTCs. This may cause another problem to occur.
B -- LEAVE VEHICLE IN P POSITION, AND CHARGE HV BATTERY IN IDLE STATUS UNTIL IDLING STOPS
A -- Continue to next step.
4. CHECK CRANKSHAFT PULLEY REVOLUTION (P POSITION)
(a) Turn the power switch off.
(b) Move the shift lever to the P position and lift up the vehicle.
(c) Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
CAUTION: Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.
Result:
B -- CHECK CRANKSHAFT PULLEY REVOLUTION (N POSITION)
A -- Continue to next step.
5. CHECK HV BATTERY
(a) Turn the power switch off.
(b) Wait 10 minutes or more.
(c) Turn the power switch on (IG).
(d) Select the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / HV ECU / DATA LIST / V1 to 20 BATT BLOCK.
(2) Techstream - Select: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 to 20.
(e) Read the data list.
Result:
B -- REPLACE HV BATTERY ASSEMBLY
A -- REPLACE HV BATTERY ASSEMBLY
6. CHECK CRANKSHAFT PULLEY REVOLUTION (N POSITION)
(a) Turn the power switch off.
(b) Move the shift lever to the N position and lift up the vehicle.
(c) Turn the crankshaft pulley using hand tools to check if the crankshaft can rotate smoothly.
CAUTION: Do not turn the power switch on (READY) while performing this inspection. Be sure to turn the power switch off before performing this inspection, to prevent the engine from starting.
Result:
B -- REPLACE HYBRID VEHICLE TRANSMISSION ASSEMBLY
A -- Continue to next step.
7. REPAIR OR REPLACE ENGINE
NEXT -- CHECK ENGINE START
8. REPLACE HYBRID VEHICLE TRANSMISSION ASSEMBLY
(a) Replace the hybrid vehicle transmission assembly Components.
NEXT -- Continue to next step.
9. CHECK ENGINE START
(a) Turn the power switch on (READY).
(b) Check if the engine starts.
HINT: Depressing the accelerator pedal with the shift lever in the P position will cause the engine to start.
Result:
CAUTION: Do not turn the power switch on (READY) repeatedly after duplicating the problem symptom indicated by DTC P3000-389 and clearing the DTCs. This may cause another problem to occur.
B -- LEAVE VEHICLE IN P POSITION, AND CHARGE HV BATTERY IN IDLE STATUS UNTIL IDLING STOPS
A -- Continue to next step.
10. CHECK HV BATTERY
(a) Turn the power switch off.
(b) Wait 10 minutes or more.
(c) Turn the power switch on (IG).
(d) Select the following menu items:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / HV ECU / DATA LIST / V1 to 20 BATT BLOCK.
(2) Techstream - Select: Powertrain / Hybrid Control / Data List / Battery Block Vol -V01 to 20.
(e) Read the data list.
Result:
B -- REPLACE HV BATTERY ASSEMBLY
A -- REPLACE HV BATTERY ASSEMBLY
