MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-796

.

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.

MULTIPORT FUEL INJECTION (MFI) DIAGNOSIS

TSB Revision

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-797

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

• Battery failed

• Malfunction of the starter motor relay.

• Malfunction of the starter motor.

• Open or shorted starting system circuit, harness 

damage, or connector damage.

• Malfunction of the transmission range switch.

• Malfunction of the ECM

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 data list item 79: 
Cranking signal.

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) Set scan tool MB991958 to the data reading mode for item 

79, Cranking Signal.

• When the engine is stopped, "OFF" will be displayed.

• When the engine is cranked, "ON" will be displayed.

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

YES : Go to Step 9.
NO :  Go to Step 2.

STEP 2. Check harness connector C-304, C-315 at 
ETACS-ECU connector 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. Measure the ignition switch-ST signal voltage at 
ETACS-ECU harness side connector C-315.
(1) Disconnect the connector C-315 and measure at the 

harness side.

(2) Turn the ignition switch to the "START" position.
(3) Measure the voltage between terminal No. 7 and ground.

• Voltage should be battery positive voltage

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts) 

present?
YES : 
Go to Step 6.
NO :  Go to Step 4.

STEP 4. Check harness connector C-210 ignition switch 
connector for damage.
Q: Is the connector in good condition?

YES : Go to Step 5.
NO :  Repair or replace it. Refer to GROUP 00E, Harness 

Connector Inspection 

P.00E-2

. Then confirm that the 

malfunction symptom is eliminated.

STEP 5. Check the ignition switch
Refer to GROUP 54A, Ignition Switch 

− Inspection − Ignition 

Switch Continuity Check 

P.54A-26

.

Q: Are there any abnormalities?

YES : Replace the Ignition Switch. Then confirm that the 

malfunction symptom is eliminated.

NO :  Repair harness wire between Ignition Switch 

connector C-210 (terminal No. 5) and ETACS-ECU 
connector C-315 (terminal No. 7) because of open 
circuit or short circuit to ground. Then confirm that the 
malfunction symptom is eliminated

STEP 6. Check for harness damage between ignition 
switch connector C-210 (terminal No. 5) and ETACS-ECU 
connector C-315 (terminal No. 7).
Q: Is the harness wire in good condition?

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

is eliminated.
