TEC FAULT CODES / TEC ERROR CODES

John Deere UIM fault codes / John Deere UIM diagnostic trouble codes

TEC Control Unit – Interface for tractor equipment. ISOBUS

TEC 000628.12 (TEC 628.12)— Control Unit Internal Fault
This diagnostic trouble code is saved if the control unit has switched to an incorrect mode (boot mode).

TEC 000629.12 (TEC 629.12)— Control Unit Internal Fault
If an internal fault occurs in the TEC control unit, this diagnostic trouble code is triggered.

TEC 000630.02 (TEC 630.02)— Control Unit Internal Fault
This diagnostic trouble code s triggered if an incorrect entry is detected in the internal memory.

TEC 000639.12 (TEC 639.12)— ISOBUS, High Error Rate
This diagnostic trouble code is saved if the data received by the TEC control unit from the ISOBUS are faulty or incomplete. This indicates a problem in the ISOBUS.

TEC 000639.14 (TEC 639.14)— ISOBUS, Very High Error Rate
This diagnostic trouble code is saved if the data received by the TEC control unit from the ISOBUS are faulty or incomplete. This indicates a problem in the ISOBUS.

TEC 001231.12 (TEC 1231.12)— Vehicle CAN BUS, High Error Rate
This diagnostic trouble code is saved if the data received by the TEC control unit from the CAN BUS are faulty or incomplete. This indicates a problem in the vehicle CAN BUS.

TEC 001231.14 (TEC 1231.14)— Vehicle CAN BUS, Very High Error Rate
This diagnostic trouble code is saved if the data received by the TEC control unit from the CAN BUS are faulty or incomplete. This indicates a problem in the vehicle CAN BUS.

TEC 522550.14 — Implement Connected to ISOBUS is Not Compatible with ISO
This diagnostic trouble code is triggered if the implement connected to the ISOBUS does not conform to ISO standard.

TEC 523652.02 — Controller Connected to Wrong Wiring Harness Connector
This diagnostic trouble code is saved if the TEC control unit detects an erroneous signal in the circuit of the control unit identification.

TEC 600006.31 — Diagnostic Trouble Code Not Known
This diagnostic trouble code is triggered by the CommandCenter (DTI) when the DTI receives a TEC diagnostic trouble code via the CAN BUS that is not stored in the DTI memory. This “general” diagnostic trouble code enables the CommandCenter (DTI) to display information relating to this unknown TEC diagnostic trouble code.
