Schematic of the Relay (Rotate Counterclockwise) (Shear)This diagnostic code is associated with the relay (rotate counterclockwise) (shear). The FMI 05 means that the ECM has determined that the current of the relay is below normal. The possible causes of this diagnostic code are listed below:
The signal circuit of the relay is open.
The return circuit of the relay is open.
The relay has failed.
The ECM has failed. This is unlikely. Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear these diagnostic codes when the original diagnostic code has been corrected. Ensure that the diagnostic code of CID 1801 FMI 05 is active before performing this procedure.Note: Use the 146-4080 Digital Multimeter for the measurements in this procedure.System Response:The diagnostic code of CID 1801 FMI 05 will be logged in the internal memory of the ECM..Test Step 1. CHECK FOR RELATED DIAGNOSTIC CODES.Note: The mode selector switch must be located in the shear position.
Use the Electronic Technician in order to verify that diagnostic codes for the mode select switch are not present. The codes that may be present are listed:
CID 1799 FMI 03
CID 1799 FMI 06Expected Result:Diagnostic codes for the mode select switch are not present.Results:
OK - Diagnostic codes for the mode select switch are not present.
