MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <3.0L ENGINE>

13B-818

CIRCUIT OPERATION

• If the selector lever is moved to "P" or "N" range 

and the ignition switch is turned to "START" posi-
tion, battery positive voltage is supplied to starter 
relay coil. With this, the starter relay turns "ON" 
the battery positive voltage is supplied to the 
starter motor (terminal No. 1) from the battery.

.

COMMENT

• Faulty starting system and the related circuit are 

suspected to be the causes.

.

TROUBLESHOOTING HINTS (The most 
likely causes for this case:) 

• Battery failed

• Malfunction of the starter motor relay.

• Malfunction of the starter motor.

• Open circuit or short circuit in the starting system 

or the related circuit or poor contact in the con-
nectors

• Malfunction of the transmission range switch.

• Malfunction of the ECM

DIAGNOSIS

STEP 1. Using scan tool MB991958, check data list.
(1) Turn the ignition switch to the "ON" position.
(2) Check the following items of the data list. Refer to Data List 

Reference Table 

P.13B-836

.

a. Item 79: Cranking signal.

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : Go to Step 2.
NO :  Repair harness wire between ETACS-ECU connector 

C-304 (terminal No. 15) and ECM connector B-11 
(terminal No. 105) because of open circuit. Then 
confirm that the malfunction symptom is eliminated.

STEP 2. Check harness connector B-110 at transmission 
range switch and harness connector B-11 at ECM for 
damage.
Q: Is the connector in good condition?

YES : Go to Step 3.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then confirm that the 

malfunction symptom is eliminated.

STEP 3. Check the transmission range switch.
Refer to GROUP 23C, On-vehicle Service 

− Essential Service 

− Transmission Range Switch Check 

P.23C-269

.

Q: Are there any abnormalities?

YES : Repair or replace it. Then confirm that the malfunction 

symptom is eliminated.

NO :  Go to Step 4.

13B-819

STEP 4. Check for open circuit or short circuit to ground or 
harness damage between transmission range switch 
connector B-110 and ECM connector B-11.
(1) Disconnect the connector B-110 and B-11 measure at the 

harness side.

(2) Measure the resistance between connector B-110 (terminal 

No. 10) and connector B-11 (terminal No. 106).

• Should be less than 2 ohms.

(3) Check for the continuity between connector B-11 (terminal 

No. 106) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Then go to Step 5.
NO :  Repair it. Then confirm that the malfunction symptom 

is eliminated.

STEP 5. Check harness connector A-27X at starter relay.
Q: Is the connector in good condition?

YES : Then go to Step 6.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then confirm that the 

malfunction symptom is eliminated.

STEP 6. Check for open circuit or short circuit to ground or 
harness damage between transmission range switch 
connector B-110 and starter relay connector A-27X.
(1) Disconnect the connector B-110 and A-27X measure at the 

harness side.

(2) Measure the resistance between connector B-110 (terminal 

No. 7) and connector A-27X (terminal No. 2).

• Should be less than 2 ohms.

(3) Check for the continuity between connector B-110 (terminal 

No. 7) and ground.

• Not continuity.

Q: Is the harness wire in good condition?

YES : Then go to Step 7.
NO :  Repair it. Then confirm that the malfunction symptom 

is eliminated.

STEP 7. Check harness connector B-10 at ECM for 
damage.
Q: Is the harness connector in good condition?

YES : Go to Step 8.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection
