Title: 2ZR-FXE (ENGINE CONTROL): SFI SYSTEM: P060444; Internal Control Module Random Access Memory (RAM) Error Data Memory Failure; 2023 - 2025 MY Corolla Corolla HV [09/2022 - ] |
DTC
|
P060444
|
Internal Control Module Random Access Memory (RAM) Error Data Memory Failure
|
MONITOR DESCRIPTION
The ECM continuously monitors its internal memory status. This self-check ensures that the ECM is functioning properly. The ECM memory status is diagnosed by internal mirroring of the main CPU and sub CPU to detect Random Access Memory (RAM) errors. If outputs from these CPUs are different and deviate from the standard, the ECM will illuminate the MIL and store this DTC.
DTC No.

CAUTION / NOTICE / HINT
HINT:
Read freeze frame data using the Techstream. 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.
PROCEDURE
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Engine > Clear DTCs
(e) Turn the power switch off.
