Circuit Description
Modules that are connected to the shared communication circuits monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. The modules have pre-recorded information about what messages are needed to be exchanged on the serial data circuits for each virtual network. The messages are usually supervised and some periodic messages are used by the receiver module as an availability indication of the transmitter module.

DTC U0401 TCM received invalid data from ECM
Conditions for Setting the DTC
The transmission control module (TCM) detects an invalid throttle position signal, engine speed signal and/or engine coolant temperature signal for more than 2 seconds.

Action Taken When the DTC Sets
• The TCM will store the DTC when a failure is detected on the first ignition cycle.
• The TCM will illuminate the HOLD lamp.
• The TCM can no longer determine the validity of any information it may or may not receive from the engine control module (ECM). Therefore the TCM substitutes default values for engine speed, throttle position, and other engine data signals.
• Transmission operation will be reduced, affecting shift points, torque converter clutch operation, and other driveability concerns.

Diagnostic Aids
• An intermittent malfunction may be caused by a fault in the electrical circuit. Inspect the wiring harness and the components for an intermittent condition. Refer to Intermittent Conditions in Engine Controls 1.6L.
• Repair any electrical circuit faults that were found. Refer to Wiring Repairs in Wiring Systems.
• Faulty ECM and/or TCM

Install a scan tool.
Turn ON the ignition, with the engine OFF.
Save the DTC and Freeze Frame information into the scan tool memory.
Perform the scan tool Clear DTC Information function for the transmission control module (TCM) and the engine control module (ECM).
Operate the vehicle for 1 minute or until the MIL illuminates.
Check the TCM for DTCs.
Is the Malfunction Indicator Lamp (MIL) On?
--
YES - Go to Step 2
NO - Repair the wiring connectors for intermittent failure

Select request DTC status from the Diagnostic Trouble Codes Information menu

Turn OFF the ignition.
Disconnect connector A from the TCM.
Turn the ignition ON, with the engine OFF.
Measure the resistance between terminal A17 of the TCM wiring connector and terminal K14 of the ECM wiring connector.
Measure the resistance between terminal A7 of the TCM wiring connector and terminal K15 of the ECM wiring connector.
Was the resistance the specified value for both circuits?
0 ohms
YES - Go to Step 5
NO - Go to Step 4

First is year make and model. A U code is data communication codes. Sorry to say, you could have done all this and it could have just been a bad wire.

Try Google

Never saw a code like that

Doesn't look right & it has to
be manufacture specific & a body
or ECU (computer) code

I think your best with a professional scan tool ,
to get enhanced euro codes,not generic

That is no generic code

Yes, there is a diagnostic connector in your 1998 Mitsubishi Chariot Grandis 2.4Gdi that you can use to get codes on the dash. The diagnostic connector is located under the dashboard, on the driver's side. To access the diagnostic connector, you will need to remove the fuse box cover. Once you have access to the diagnostic connector, you will need to use a diagnostic tool to read the codes. A diagnostic tool is a device that can be used to communicate with the vehicle's computer. There are many different diagnostic tools available, both professional and DIY. To use a diagnostic tool, you will need to connect the tool to the diagnostic connector. Once the tool is connected, you will need to select the option to read codes. The tool will then display the codes on its screen. The codes will be a series of numbers and letters. Each code will represent a different problem with the vehicle. You can use the code book that came with your vehicle to look up the meaning of the codes. Once you know the meaning of the codes, you can start to troubleshoot the problem. If you are not comfortable troubleshooting the problem yourself, you can take the vehicle to a qualified mechanic for diagnosis and repair. Here are the steps on how to self-diagnose your 1998 Mitsubishi Chariot Grandis 2.4Gdi using the diagnostic connector: Locate the diagnostic connector under the dashboard, on the driver's side. Remove the fuse box cover. Connect the diagnostic tool to the diagnostic connector. Select the option to read codes. The tool will display the codes on its screen. Look up the meaning of the codes in the code book that came with your vehicle. Start to troubleshoot the problem based on the meaning of the codes. If you are not comfortable troubleshooting the problem yourself, take the vehicle to a qualified mechanic for diagnosis and repair.

Have you had the electronic engine control system scanned/tested for fault codes? It will need to be scanned to obtain the fault codes, this is key to finding out what the problem may be that is causing the stall. The fault code test can be done free of charge by any Autozone auto parts store, Aamco transmission or Kragen/Oriley auto parts store. Ask for a "OBD2" (on board diagnostics generation 2) fault code test.
