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 

P.13B-882

. 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> 

P.42B-15

 or GROUP 42C, ID Codes Registration 

Judgment Table <Vehicles with WCM> 

P.42C-10

. 

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 

P.00-15

.

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 

P.13B-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P050B set?

YES : Retry the troubleshooting.
NO :  The inspection is complete.

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-583

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
