MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-665

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 harness connector B-08 at throttle actuator 
control motor and harness connector B-10, B-11 at ECM 
for damage.
Q: Is the harness connector in good condition?

YES : Go to Step 2.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then go to Step 6.

STEP 2. Check the throttle actuator control motor.
(1) Disconnect the connector B-08.
(2) Measure the resistance between throttle actuator control 

motor side connector terminal No. 1 and No. 2.

Standard value: 0.3 

 80 Ω [at 20°C (68°F)]

Q: Is the measured resistance between 0.3 and 80 ohms [at 

20

°C (68°F)]?

YES : Go to Step 3.
NO :  Replace the throttle body assembly. Then go to Step 

6.

STEP 3. Check the continuity at ECM harness side 
connector B-11.
(1) Disconnect the connector B-11 and measure at the harness 

side.

(2) Measure the continuity between terminals No. 71, No. 83 

and ground.

• Should be less than 2 ohms.

Q: Does continuity exist?

YES : Go to Step 4.
NO :  Check harness connector A-66 at intermediate 

connector for damage, and repair or replace as 
required. Refer to GROUP 00E, Harness Connector 
Inspection 

P.00E-2

. If intermediate connector is in 

good condition, repair harness wire between ECM 
connector B-11 (terminals No. 71, No. 83) and ground 
because of open circuit or harness damage. Then go 
to Step 6.

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-666

STEP 4. Check for harness damage between throttle 
actuator control motor connector B-08 and ECM connector 
B-10.
(1) Disconnect the connector B-08 and B-10 measure at the 

harness side.

(2) Measure the resistance between B-08 connector and B-10 

connector.

a. Connector B-08 (terminal No. 1) and connector B-10 ter-

minal No. 15).

b. Connector B-08 (terminal No. 2) and connector B-10 

(terminal No. 16).

• Should be less than 2 ohms.

Q: Is the measured resistance less than 2 ohms?

YES : Then go to Step 5.
NO :  Repair it. Then go to Step 6.

STEP 5. 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 again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2100 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 6.

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
