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
.
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
. 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
.
Q: Are there any abnormalities?
YES : Repair or replace it. Then confirm that the malfunction
symptom is eliminated.
NO : Go to Step 4.

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
. 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
. Then confirm that the
malfunction symptom is eliminated.
