DESCRIPTION
The ECM continuously monitors its internal memory status, internal circuits, and output signals transmitted to the throttle actuator. This self-check ensures that the ECM is functioning properly. If any malfunction is detected, the ECM sets the appropriate DTC and illuminates the MIL.The ECM memory status is diagnosed by internal "mirroring" of the main CPU and the sub CPU to detect Random Access Memory (RAM) errors. The 2 CPUs also perform continuous mutual monitoring. The ECM illuminates the MIL and sets a DTC if: 1) outputs from the 2 CPUs are different or deviate from the standards, 2) the signals sent to the throttle actuator deviate from the standards, 3) a malfunction is found in the throttle actuator supply voltage, and 4) any other ECM malfunction is found.
| DTC No. | DTC Detection Condition | Trouble Area |
| P0604 P0606 P0607 P060A P060D P060E P0657 | ECM internal error (1 trip detection logic) | ECM |
INSPECTION PROCEDURE
Read freeze frame data using the intelligent tester. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.| 1.CHECK ANY OTHER DTCS OUTPUT |
Connect the intelligent tester to the DLC3.
Turn the ignition switch on (IG) and turn the tester on.
Select the following menu items: Powertrain / Engine and ECT / DTC.
Read the DTC.
- Result:
Result Proceed to DTC P0604, P0606, P0607, P060A, P060D, P060E and/or P0657 are output A DTC is not output B
