HYBRID CONTROL SYSTEM, Diagnostic DTC:P060A94

DTC Code DTC Name
P060A94 Hybrid/EV Powertrain Control Module Monitoring Processor Unexpected Operation

DTC SUMMARY


  1. 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.

DTC No. Detection Item DTC Detection Condition Trouble Area MIL Warning Indicate
P060A94 Internal Control Module Monitoring Processor Performance Unexpected Operation

  • The sub CPU value received by the main CPU of the hybrid control ECU exceeds the threshold for a certain period of time.

  • The hybrid vehicle control ECU assembly detects an internal malfunction due to an abnormal calculation or sensor malfunction.

  1. Connect the GTS to the DLC3.

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

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

  4. Turn the power switch off and wait for 2 minutes or more.

  5. Turn the power switch on (IG) and turn the GTS on.

  6. Turn the power switch on (READY) and wait for 10 seconds or more.

  7. Enter the following menus: Powertrain / Hybrid Control / Utility / All Readiness.

  8. Check the DTC judgment result.

    Tech Tips


    • 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.

PROCEDURE


  1. CHECK DTC OUTPUT (MOTOR GENERATOR)


    1. Connect the GTS to the DLC3.

    2. Turn the power switch on (IG).

    3. Enter the following menus: Powertrain / Motor Generator / Trouble Codes.

    4. Check for DTCs.
