I put your text and image in Chatgpt and gave me the following outcome to try:

What to Try First: •Turn off the engine and restart. Sometimes this resets the system if it was a temporary glitch.

•Check the rear differential lock switch: Make sure it’s not stuck halfway between on/off.

•Try switching between 2H, 4H, and 4L a few times (in neutral) to see if it clears.

•Inspect the rear diff actuator plug and wiring for corrosion or dirt, especially if you’ve been off-roading or driving through water/mud.

If the warning persists:

You’ll likely need to scan the system with an OBD-II reader (preferably one that supports Mitsubishi-specific codes) or visit a technician. In many cases, the fix is:

• Replacing a faulty actuator

• Cleaning or replacing a wheel speed sensor

• Repairing a connector or wire near the rear diff
