Mitsubishi Multi Communication System Reset: A Step-by-Step Guide

The Mitsubishi Multi Communication System (MMCS) is a sophisticated infotainment and navigation system used in various Mitsubishi vehicles. While it's designed to provide a seamless driving experience, sometimes it may encounter issues that require a reset. In this post, we'll walk you through the process of resetting the MMCS system.

Why Reset the MMCS System?

Before we dive into the reset process, let's briefly discuss some common reasons why you might need to reset the MMCS system:

Resetting the MMCS System:

There are two methods to reset the MMCS system: a soft reset and a hard reset.

Method 2: Soft Reset Using Steering Wheel Controls (Alternative)

If your touchscreen is unresponsive and the power button doesn’t work, try this hidden combination:

Steps:

  1. With ignition on, press and hold the Phone Pickup button (on steering wheel) for 10 seconds.
  2. While still holding, press the Voice Command button three times quickly.
  3. The system should force a restart.

This method is documented in Mitsubishi service bulletins for the MMCS Gen 2 units.

Step 1: Accessing the Service Menu

The button combination varies slightly by generation and region. Try these sequences until one works for you.

Sequence A (Common for Outlander/ASX Gen 3):

  1. Turn ignition ON.
  2. Press and hold the MAP button.
  3. While holding MAP, press and hold the DISP button (or the dial knob).
  4. Hold both for 5+ seconds until a "Service Menu" or "Diagnosis Menu" appears.

Sequence B (Common for Pajero/Lancer):

  1. Turn ignition ON.
  2. Press and hold the SCREEN button.
  3. While holding SCREEN, press the TONE button repeatedly (3 times).

Sequence C (The "1-2-3" Method - Older Systems):

  1. Turn ignition ON.
  2. Press and hold

When a Reset Won’t Help

If your screen remains black or shows distorted colors after a reset:

For most 2014–2020 Models (Outlander/ASX):

  1. Tap MENU on the home screen.
  2. Select Setup (gear icon).
  3. Tap System.
  4. Scroll down and select Factory Data Reset.
  5. Enter the security code (usually 0000 or 1234 — check your owner’s manual if these do not work).
  6. Confirm Yes. The system will wipe data and restart.

Method 2: Factory Reset via Settings Menu

Use this if the system is responsive but has persistent issues (e.g., Bluetooth pairing failures or map errors).

  1. Turn the ignition to ON or start the engine.
  2. On the MCS screen, go to Menu → Setup (or Settings).
  3. Scroll to System or General (varies by model year).
  4. Look for Factory Data Reset, Restore Defaults, or Clear All Data.
  5. Confirm the action. The system will restart and reboot to factory state.

Important: Soft Reset vs. Hard Reset vs. Factory Reset

Before proceeding, understand the three levels of reset:

| Type | Effect | Data Loss? | | --- | --- | --- | | Soft Reset | Reboots the system like restarting a computer. | No – Preserves radio presets, paired phones, navigation history. | | Hard Reset | Disconnects all power to force a full reboot. | Minimal – Clock and some temporary settings may reset. | | Factory Reset | Restores system to original out-of-box state. | Yes – Erases all saved data (pairings, presets, addresses). |

Always start with a soft reset. Only move to factory reset if problems persist.
