MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS
TSB Revision
MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>
13B-582
DIAGNOSIS
Required Special Tools
• MB991958: Scan tool (M.U.T.-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: USB Cable
• MB991910: Main Harness A
STEP 1. Check the throttle body. (throttle valve area)
Q: Is the throttle valve area dirty?
YES : Perform cleaning. Refer to Throttle body (throttle
valve area) cleaning
. Then go to Step 3.
NO : Repair it. Then go to Step 2.
STEP 2. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
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) Connect scan tool MB991958 to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P050B set?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, ID Code
Registration Judgment Table <Vehicles with KOS>
or GROUP 42C, ID Codes Registration
Judgment Table <Vehicles with WCM>
Then go to Step 3.
NO : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
− How to
Cope with Intermittent Malfunctions
.
STEP 3. Test the OBD-II drive cycle.
(1) Carry out test drive with the drive cycle pattern. Refer to
Diagnostic Function
− OBD-II Drive Cycle − Pattern 23
(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P050B set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

DTC P0513: Immobilizer Malfunction
.
TECHNICAL DESCRIPTION
• ECM monitors the communication condition with
the immobilizer-ECU. When an abnormality in
communication is found, ECM prevents engine
start.
.
DTC SET CONDITIONS
Check Condition
• Ignition switch is "ON" position.
Judgment Criterion
• When the communication error between ECM
and the immobilizer-ECU continues for 2 seconds
or more.
or
• When it was different in the encrypted code sent
from immobilizer-ECU and operation result by
ECM.
.
TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
• Malfunction of CAN system.
• Malfunction of immobilizer system.
• ECM failed.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan Tool (M.U.T.-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: USB Cable
• MB991910: Main Harness A
STEP 1. Using scan tool MB991958, check VIN Information.
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) Connect scan tool MB991958 to the data link connector.
(2) Set scan tool MB991958 to the coding mode for VIN
Information.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Has VIN (current) been written?
YES : Go to Step 2.
NO : Write VIN. Then go to Step 3.

STEP 2. Using scan tool MB991958, diagnose CAN bus
line.
(1) Turn the ignition switch to the "ON" position.
(2) Diagnose CAN bus line.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line normal?
YES : Go to Step 3.
NO : Repair the CAN bus line. Refer to GROUP 54C,
Diagnosis
− Can Bus Diagnostics Table
.
Then go to Step 4.
STEP 3. Using scan tool MB991958, read the immobilizer
diagnostic trouble code (DTC).
(1) Turn the ignition switch to the "ON" position.
(2) Read the immobilizer-DTC.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the immobilizer-DTC set?
YES : Refer to GROUP 42B, Diagnosis
− Diagnostic
Trouble Code Chart <Vehicles with KOS>
or GROUP 42C, diagnosis
− Diagnostic Trouble Code
Chart <Vehicles with WCM>
NO : Go to Step 4.
STEP 4. Using scan tool MB991958, read the diagnostic
trouble code (DTC)
(1) Turn the ignition switch to the "ON" position.
(2) After the DTC has been deleted, read the DTC again.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P0513 set?
YES : Replace the ECM. When the ECM is replaced,
register the ID code. Refer to GROUP 42B, Diagnosis
− ID Codes Registration Judgment Table <Vehicles
or GROUP 42C, Diagnosis
− ID
Codes Registration Judgment Table <Vehicles with
WCM>
