DESCRIPTION
The HV battery is composed of 70 cells (3.7 V each) in series. The battery ECU assembly monitors the internal resistance of each HV battery cell to detect malfunctions of the HV battery.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P33DA1E | Hybrid/EV Battery Stack 1 Circuit Resistance Out of Range | The difference in internal resistance of each cell of the No. 1 HV supply stack sub-assembly exceeds the threshold. (1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
P33DB1E | Hybrid/EV Battery Stack 2 Circuit Resistance Out of Range | The difference in internal resistance of each cell of the No. 2 HV supply stack sub-assembly exceeds the threshold. (1 trip detection logic) |

MONITOR DESCRIPTION
If there is an abnormal internal resistance in the battery cells, the battery ECU assembly determines that a malfunction has occurred. When the malfunction detection condition is satisfied, the battery ECU assembly will illuminate the MIL and store a DTC.

HINT:
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly.
If the HV battery stored without insulating the connectors and terminals, electric shock or fire may result.

PROCEDURE
1. | CHECK DTC OUTPUT (HV BATTERY) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Enter the following menus: Powertrain / HV Battery / Trouble Codes.
(d) Check if DTCs are output.
Powertrain > HV Battery > Trouble Codes Result | Proceed to |
---|---|
"P33DA1E" is output. | A |
"P33DB1E" is output. | B |
(e) Turn the power switch off.
B | GO TO STEP 4 |
|
2. | CHECK TOTAL DISTANCE DRIVEN |
(a) Read the odometer to check the total distance the vehicle has been driven.
Result | Proceed to | |
---|---|---|
Total distance driven is less than 200000 km (124280 mile) | A | |
Total distance driven is 200000 km (124280 mile) or more | Current total distance driven - total distance driven when hybrid battery terminal block replaced = less than 200000 km (124280 mile) *1 | |
Other than above | B |
HINT:
*1: If the hybrid battery terminal block has been replaced, use the total distance driven since it was replaced.

(a) Read the odometer to check the total distance the vehicle has been driven.
Result | Proceed to | |
---|---|---|
Total distance driven is less than 200000 km (124280 mile) | A | |
Total distance driven is 200000 km (124280 mile) or more | Current total distance driven - total distance driven when hybrid battery terminal block replaced = less than 200000 km (124280 mile) *1 | |
Other than above | B |
