Mitsubishi Outlander: Diagnostic Function

ON-BOARD DIAGNOSTICS

If the ASC-ECU detects any problem in the CAN communication line or the ECUs, which the ASC-ECU is communicating with, it stores a diagnostic trouble code. The DTCs have 73 items. The DTCs can be confirmed by connecting scan tool MB991958 (M.U.T.-III sub assembly.) The stored DTCs are not erased even after the ignition switch has been turned to the LOCK (OFF) position, or the battery has been disconnected. The DTCs can be erased by operating scan tool MB991958 (M.U.T.-III sub assembly.)

HOW TO CONNECT THE SCAN TOOL (M.U.T.-III)

Required Special Tools:

CAUTION To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.

1. Ensure that the ignition switch is at the "LOCK" (OFF) position.

2. Start up the personal computer.

DIAGNOSTIC FUNCTION

ASC-ECU has the following functions for easier system checks. All the following items can be diagnosed using the scan tool.

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the scan tool.

When detecting fault and storing the DTC, the ECU connected to CAN bus line obtains the data before the determination of the DTC and the data when the DTC is determined, and then stores the ECU status of that time. By analyzing each data from scan tool, the troubleshooting can be performed more efficiently.

The displayed items are as the table below.

FAIL-SAFE FUNCTIONS

ASC-ECU constantly monitors the input and output signals. If an error is detected in the system, ASC-ECU sends a fail signal and the corresponding indicator light is illuminated or blinks. Various controls are processed depending on the cause of malfunction as shown below.
