After repair of the trouble area, the diagnostic code retained\nin memory by the ECT ECU must be canceled by removing the fuse DOME (20A) for 10 seconds or more, depending on ambient temperature (the lower the temperature,\nthe longer the fuse must be left out) with the ignition switch\nOFF.\nHINT:\n• Cancellation can be also done by removing the battery\nnegative (—) terminal, but in this case other memory systems (TCCS diagnosis memory, etc.) will be also canceled out.\n• The diagnostic code can be also canceled out by disconnecting the ECT ECU connector.\n• If the diagnostic code is not canceled out, it will be retained by the ECT ECU and appear along with a new code\nin event of future trouble.\n\n2. After cancellation, perform a road test to confirm that a\n\"normal code\" is now read on the O/D OFF light.\n\n[THIS IS FIGURE: Diagram showing DOME fuse location in fuse box, labeled
