DESCRIPTION
The power management control ECU monitors its internal operation, it will set DTCs and perform fail-safe control when it detects the following malfunctions. If any of the following DTCs are output, replace the power management control ECU.DTC No. | INF Code | DTC Detection Condition | Trouble Area |
P0A1D | 144 | ECU internal error (1 trip detection logic) | Power management control ECU |
MONITOR DESCRIPTION
The power management control ECU performs many diagnostic tests to verify proper operation of internal ECU systems. In one of these tests, the power management control ECU performs a self-test. If the power management control ECU detects an internal problem during this self-test, it will conclude that there is an internal malfunction. The power management control ECU will illuminate the MIL and set a DTC.MONITOR STRATEGY

CONFIRMATION DRIVING PATTERN
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 30 seconds or more.
- Turn the ignition switch to ON (READY) and after a few seconds, turn the ignition switch off. [A]
- Repeat [A] 3 times. [B]
- Turn the ignition switch to ON (IG) and turn the Techstream on.
- Enter the following menus: Powertrain / Hybrid Control / Trouble Codes. [C]
- Read the current DTCs.
- HINT:
- If a current DTC is output, the system is malfunctioning.
- If a current DTC is not output, perform the following procedure.
- Check that permanent DTCs are cleared. If no permanent DTC is output, the system is normal.
- If the permanent DTCs are not cleared, perform the universal trip, and then check for permanent DTCs again.
INSPECTION PROCEDURE
- HINT:
- After the repair, clear the DTCs and perform the following procedure to check that DTCs are not output.
- Turn the ignition switch to ON (IG) and wait for 30 seconds or more.
