CID 0819 FMI 06 Display Data Link Current Above Normal - Test
This failure is recorded when the VIMS main module reads the voltage of the Display Data Link and the voltage is below normal. The circuit is shorted to ground.
- DISCONNECT THE DISPLAY MODULES.
- Disconnect the display modules from the machine harness one at a time and reconnect the display modules from the machine harness one at a time.
- Check whether the fault CID 0819 FMI 06 is present.
Expected Results: The fault CID 0819 FMI 06 remains.
Results:
- OK - Fault has not changed. The fault CID 0819 FMI 06 remains. Repeat this process for each module. Proceed to Step 2.
- NOT OK - Fault is not displayed. Replace the module.
- CHECK FOR SHORT TO GROUND
- Turn the disconnect switch and the key start switch to the OFFposition.
- Disconnect the machine harness from the VIMS main module and the display modules.
- Measure the resistance at the machine harness connector of the VIMS main module between frame ground and the Display Data Link circuit connector contacts: 26, 27 and 28
Expected Results:The Resistance is greater than 5000 ohms.
Results:
- OK - Resistance is greater than 5000 ohms. The harness circuit resistance is correct. The VIMS main module is faulty. Replace the VIMS module. Refer to the Testing and Adjusting, "Module-Replace" section. STOP.
- NOT OK - Resistance is less than 5000 ohms. The machine harness is faulty. The display data link is shorted to ground. Repair the machine harness or replace the machine harness. STOP.
