    SC544 on MPC4502

    SC544 error message displayed on MPC4502, used fuse M0264371 and SP 5810-002 to reset the error but "failed" appears immediately after I press Execute and nothing happens. Thermostats and fusing lamps are good.

      You have to first determine and repair the initial cause of the error code, then you can reset it.

          Reset fuser sc code and activate fuser high temp start. If the high temp is failing you could have a bad fuse installed. The only time I've ever had it fail was when I forgot to install the fuse.

                  It is possible to plug the fuse into the thermistor connector and the thermistor into the fuse connector. that will give you the results you describe, 5810-2 will fail. the two connectors are identical!!!!!!!!

                      To reset sc 544 need a pico fuse that comes in a rebuild kit for sp5- 810-2 to work otherwise show fail

                              I wonder if that's why they moved the connector for the fuse to the underside of the fusing assy for the 03/04 series?
