MULTIPORT FUEL INJECTION (MFI)
13A-7
NOTE: If the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates
because of a malfunction of the powertrain control module (PCM), transmission between scan tool and the
PCM is impossible. In this case, the diagnostic trouble code cannot be read.
NOTE: After the PCM has detected a malfunction, the Malfunction Indicator Lamp (SERVICE ENGINE
SOON or Check Engine Lamp) illuminates when the engine is next turned on and the same malfunction is
re-detected. However, for items marked with a "*" in the DTC NO. column, the Malfunction Indicator Lamp
(SERVICE ENGINE SOON or Check Engine Lamp) illuminates only on the first detection of the malfunction.
NOTE: After the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates,
it will be switched off under the following conditions.
.
•
When the PCM monitored the power train malfunction three times* and met set condition requirements, it
detected no malfunction. *: In this case, "one time" indicates from engine start to stop.
•
For misfiring or a fuel trim malfunction, when driving conditions (engine speed, engine coolant tempera-
ture, etc.) are similar to those when the malfunction was first recorded.
NOTE: Sensor 1 indicates the sensor mounted at a position closest to the engine, and sensor 2 indicates the
sensor mounted at the position second closest to the engine.
NOTE: Bank 1 indicates the right bank side cylinder, and bank 2 indicates the left bank side cylinder.

HOW TO CONNECT THE SCAN TOOL (MUT-III)
Required Special Tools:
• MB991958: Scan Tool (MUT-III Sub Assembly)
• MB991824: V.C.I
• MB991827: USB Cable
• MB991911: Main Harness B
CAUTION
To prevent damage to scan tool MB991958, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991958.
1. Ensure that the ignition switch is at the "LOCK" (OFF)
position.
2. Start up the personal computer.
3. Connect special tool MB991827 to special tool MB991824
and the personal computer.
4. Connect special tool MB991911 to special tool MB991824.
5. Connect special tool MB991911 to the data link connector.
6. Turn the power switch of special tool MB991824 to the "ON"
position.
NOTE: When the special tool MB991824 is energized, spe-
cial tool MB991824 indicator light will be illuminated in a
green color.
7. Start the MUT-Ill system on the personal computer.
NOTE: Disconnecting the scan tool MB991958 is the
reverse of the connecting sequence, making sure that the
ignition switch is at the "LOCK" (OFF) position.
