Overview:The Fuller Advantage transmission may be equipped with a J1939 Shift Control Device. This version of the Shift Control Device uses the J1939 Data Link to broadcast the driver’s shift request to the Transmission Electronic Control Unit (TECU). The system includes redundant neutral request and neutral confirmation signals hard-wired between the Shift Control Device and TECU. These redundant signals allow the transmission to achieve neutral if the J1939 Data Link fails. Fault Code 13 indicates that either the TECU lost J1939 Data Link communications with the Shift Control Device or that the neutral request status received over J1939 and the...

Overview:The Fuller Advantage transmission may be equipped with an analog Shift Control Device. The Transmission Electronic Control Unit (TECU) supplies the analog Shift Control Device with a 5-volt reference through OEM wiring. This voltage is reduced by resistive ladder circuitry in the shift device, based on the position the driver selects. The return voltage to the TECU indicates the position of the Shift Lever. Fault Code 14 indicates the TECU has detected an electrical fault in either the OEM-supplied wiring or Shift Control Device. Detection:TECU monitors the voltage from the analog Shift Control Device. Fault Code 14 sets when the...
