P1A60

HYBRID / BATTERY CONTROL: HYBRID BATTERY SYSTEM: P1A60-123, P1A62-123: Hybrid Battery Cell High Voltage Stack "B"
P1A62-123 - Hybrid Battery Cell Extreme High Voltage Stack "B"

DESCRIPTION

- The power management control ECU alerts the driver and performs fail-safe control based on error signals sent from the battery smart unit.

MONITOR DESCRIPTION

- If the battery smart unit detects that the voltage of a battery cell becomes too high, the power management control ECU will illuminate the MIL and set a DTC.

COMPONENT OPERATING RANGE

CONFIRMATION DRIVING PATTERN

1. Connect the Techstream to the DLC3.

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

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

4. Turn the power switch off.

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

6. Perform a universal trip.

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

8. Check that permanent DTCs are cleared.

HINT
- If a permanent DTC is output, the system is malfunctioning.
- If no permanent DTC is output, the system is normal.

INSPECTION PROCEDURE

CAUTION:
- Before inspecting the high-voltage system or disconnecting the low voltage connector of the inverter with converter assembly or electric vehicle charger assembly, turn the power switch off. Also, take safety precautions such as wearing insulated gloves and removing the service plug grip to prevent electrical shocks. After removing the service plug grip, put it in your pocket to prevent other technicians from accidentally reconnecting it while you are working on the high-voltage system.
- After removing the service plug grip, wait for at least 10 minutes before touching any of the high-voltage connectors or terminals. After waiting for 10 minutes, check the voltage at the terminals in the inspection point in the inverter with converter assembly. The voltage should be 0 V before beginning work Hybrid Battery System.
HINT
Waiting for at least 10 minutes is required to discharge the high-voltage capacitor inside the inverter with converter assembly and electric vehicle charger assembly.

- When disposing of HV batteries and hybrid vehicle supply stack sub-assemblies, make sure to return them through an authorized collection agent who is capable of handling them safely. If they are returned via the manufacturer specified route, they will be returned properly and in a safe manner by an authorized collection agent.
- Before returning the HV battery or a hybrid vehicle supply stack sub-assembly, make sure to perform a recovery inspection Testing and Inspection.
- Make a note of the output DTCs as some of them may be necessary for recovery inspection of the HV battery and hybrid vehicle supply stack sub-assemblies.
NOTICE:
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) auxiliary battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) auxiliary battery terminal notices before proceeding with work Service Precautions.
