Hybrid Control System

HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P060B-134, P060B-135, P060B-570: Internal Control Module A/D Processing Performance
P060B-570 - Internal Control Module A/D Processing Performance

DESCRIPTION

The power management control ECU (HV CPU) monitors its internal operation and it will set this DTC when it detects an internal malfunction. If this DTC is output, replace the power management control ECU (HV CPU).





MONITOR DESCRIPTION

The power management control ECU (HV CPU) performs diagnostic tests to verify proper operation of internal ECU systems. One of these monitors the rationality of internal analog (signal) to digital conversions. The power management control ECU (CPU) monitors the internal A/D (Analog/Digital converter) value. If there is an A/D converter malfunction, the power management control ECU (HV CPU) will illuminate the MIL and set a DTC.

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 after a few seconds, turn the power switch off. [A]

6. Repeat [A] 3 times. [B]

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

8. Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [C]

9. Check that permanent DTCs are cleared.

10. If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.

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