TEI FAULT CODES / TEI ERROR CODES

John Deere TEI fault codes / John Deere TEI diagnostic trouble codes

TEI Control Unit – Tractor Electronic Interface

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

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

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

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

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

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

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

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

TEI 523652.02 — Control Unit 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.

TEI 600006.31 — Diagnostic Trouble Code Not Known
This diagnostic trouble code is triggered by the CommandCenter (DTI) when the DTI receives a TEI 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 TEI diagnostic trouble code.
