DTC |
P060A94 |
Hybrid/EV Powertrain Control Module Monitoring Processor Unexpected Operation |
DTC SUMMARY
MALFUNCTION DESCRIPTION
The main CPU and sub CPU of the hybrid vehicle control ECU assembly monitor their internal operation and each other for malfunctions.
The cause of this malfunction may be the following:
Hybrid vehicle control ECU assembly internal malfunction
- Hybrid vehicle control ECU assembly malfunction
Vehicle speed sensor malfunction
- Discrepancy between motor resolver signal and actual vehicle speed
DESCRIPTION
The hybrid vehicle control ECU assembly monitors its internal operation and will store these DTCs when it detects an internal malfunction.

- Connect the Techstream to the DLC3.
- Turn the power switch on (IG) and turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the power switch off and wait for 2 minutes or more.
- Turn the power switch on (IG) and turn the Techstream on.
- Turn the power switch on (READY) and wait for 10 seconds or more.
- Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.
-
Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform driving pattern again.
