MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-613

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, 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) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the diagnostic trouble code other than P061C set?

YES : Refer to Diagnostic Trouble Code Chart 

P.13B-50

. 

NO :  Go to Step 2. 

STEP 2. 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 P061C 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 

with KOS> 

P.42B-15

 or GROUP 42C, Diagnosis 

− 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.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-614

STEP 3. Test the OBD-II drive cycle.
(1) Carry out a test drive with the drive cycle pattern. Refer to 

Diagnostic Function 

− OBD-II Drive Cycle Pattern 22 

P.13B-11

.

(2) Check the diagnostic trouble code (DTC).
Q: Is DTC P061C set?

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

DTC P061F: Internal Control Module Throttle Actuator Controller Performance Problem

.

TECHNICAL DESCRIPTION

• To judge whether fail-safe control can be per-

formed, check that power supply to the throttle 
actuator control motor circuit can be stopped by 
turning the throttle actuator control motor relay to 
OFF position momentarily.

.

DTC SET CONDITIONS

Check Condition

• Ignition switch is "ON" position.

Judgment Criterion

• Power supply to the throttle actuator control 

motor cannot be shut down (though power supply 
is stopped).

.

TROUBLESHOOTING HINTS (The most 
likely causes for this code to be set are:)

• Throttle actuator control motor relay circuit failed.

• 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

DTC P0622: Generator FR Terminal Circuit Malfunction

.

CIRCUIT OPERATION

• The ECM (terminal No. 61) apply a battery posi-

tive voltage into the generator FR terminal No. 4 
via resistance inside the unit.

.

TECHNICAL DESCRIPTION

• When the generator field coils are controlled, the 

generator FR terminal inputs signal to the ECM.

• The ECM detects the generator output with the 

input signal, and controls the idle air control
