This diagnostic trouble code is generated if a data transfer problem occurs between the TEC control software and the RLC control software. The reception of one, several, or all of the CAN messages transmitted by the TEC control software is intermittent or non-existent, possibly due to a loose wire. This indicates a problem in the…
