MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI)

13A-8

NOTE: If the Malfunction Indicator Lamp (SERVICE ENGINE SOON or Check Engine Lamp) illuminates 
because of a malfunction of the powertrain control module (PCM), communication between scan tool 
MB991958 (MUT-III Sub Assembly) and the PCM is impossible. In this case, the diagnostic trouble code can-
not 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)

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-III 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.

HOW TO READ AND ERASE DIAGNOSTIC 
TROUBLE CODES.
