Hi my name is***** will be glad to try to help.

030 is the MID (Module Identifier) for the monitor ECM,
248 is the CID (Component Identifier) for the display panel data link,
02 is the FMI (Failure Mode Identifier) for an intermittent or erratic problem.

This diagnostic code is recorded when the main display module does not receive expected information. The following example shows a possible diagnostic code. The information from the actual gear status is not being received from other electronic control modules through the CAT data link. The information from the CAT data link indicates the abnormal values in the readout. The possible causes of this diagnostic code are listed below. The causes are listed in order of probability:

Poor electrical connection at a machine harness connector

The circuit for the CAT data link in the machine harness is shorted to ground.

The circuit for the CAT data link in the machine harness is shorted to the +battery.

The circuit for the CAT data link in the machine harness is open.

An electronic control module which uses the CAT data link has failed.
