DTC P060A Internal Control Module Monitoring Processor Performance


DESCRIPTION

The main CPU and sub CPU of the ECM perform data communication between each other. The main CPU monitors the communications and WDC pulses from the sub CPU. When the signal malfunctions below are detected, a DTC is stored.

DTC No.
DTC Detection Condition
Trouble Area
P060A
A CPU reset is performed after one of the following conditions is met (1 trip detection logic):
  1. There is an ECM main CPU error.
  2. There is an ECM sub CPU error.
  3. There is an electronic throttle monitoring CPU error.
ECM

MONITOR STRATEGY


Required sensors/Components
ECM
Frequency of operation
Once per driving cycle

CONFIRMATION DRIVING PATTERN

  1. Connect the intelligent tester to the DLC3.
  2. Turn the ignition switch to ON and turn the intelligent tester on.
  3. Clear the DTCs (even if no DTCs are stored, perform the clear DTC operation).
  4. Turn the intelligent tester off.
  5. Turn the ignition switch off.
  6. Disconnect the intelligent tester.
  7. Disconnect the cable from the negative (-) battery terminal and wait for 1 minute.
  8. Connect the cable to the negative (-) battery terminal.
  9. Connect the intelligent tester to the DLC3.
  10. Turn the ignition switch to ON and turn the intelligent tester on.
  11. Wait 16 seconds or more.
  12. Enter the following menus: Powertrain / Engine / DTC.
  13. Read the pending DTCs.
    HINT:
    1. If a pending DTC is output, the system is malfunctioning.
    2. If a pending DTC is not output, perform the following procedure.
  14. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  15. Input the DTC: P060A.
  16. Check the DTC judgment result.

    Tester Display
    		Description
    NORMAL
    1. DTC judgment completed
    2. System normal
    ABNORMAL
    1. DTC judgment completed
    2. System abnormal
    INCOMPLETE
    1. DTC judgment not completed
    2. Perform driving pattern after confirming DTC enabling conditions
    N/A
    1. Unable to perform DTC judgment
    2. Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit
    HINT:
    1. If the judgment result shows NORMAL, the system is normal.
    2. If the judgment result shows ABNORMAL, the system has a malfunction.
  17. If the judgment result is INCOMPLETE or N/A and no pending DTC is output, perform a universal trip and check for permanent DTCs (HILUX_TGN26 RM000000PDK130X.html).
    HINT:
    1. If a permanent DTC is output, the system is malfunctioning.
    2. If no permanent DTC is output, the system is normal.
