CID 0822 FMI 06 Display Backlighting Current Above Normal - Test
This diagnostic code is recorded when the VIMS main module reads the current of the display backlight return circuit and the current is above normal.
- CHECK FOR SHORT TO GROUND
- Turn the key start switch and the disconnect switch to OFF position.
- Disconnect the machine harness from the VIMS main module. Disconnect the message center display backlights and disconnect the speedometer/tachometer module's display backlights.
- Measure the resistance at the machine harness connector of the VIMS main module between frame ground and the display backlight return circuit connector contact 3.
Expected Resutls: 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 has failed. 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 has failed. There is a short between frame ground and the display backlight return circuit in the machine harness. Repair the machine harness or replace the machine harness. STOP.
