STEP 4. 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.

• Continuity (2 ohms or less)

Q: Does continuity exist?

YES : Go to Step 5.
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 9.

STEP 5. Check harness connector B-10 at ECM for
damage.
Q: Is the harness connector in good condition?

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

Connector Inspection

P.00E-2

. Then go to Step 9.

STEP 6. Check for open circuit and harness damage
between throttle actuator control motor connector B-08
(terminal No. 1) and ECM connector B-10 (terminal No. 15).
Q: Is the harness wire in good condition?

YES : Go to Step 7.
NO : Repair it. Then go to Step 9.

STEP 7. Check for open circuit and harness damage
between throttle actuator control motor connector B-08
(terminal No. 2) and ECM connector B-10 (terminal No. 16).
Q: Is the harness wire in good condition?

YES : Go to Step 8.
NO : Repair it. Then go to Step 9.

MULTIPORT FUEL INJECTION (MFI) <2.4L ENGINE>

13A-628

STEP 8. 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) After the DTC has been deleted, 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 Code 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 9.

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

P.00-15

.

STEP 9. 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) After the DTC has been deleted, read the DTC again.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P2100 set?

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

DTC P2101: Throttle Actuator Control Motor Magneto Malfunction

.

CIRCUIT OPERATION

• Controls the current that is applied from ECM

(terminals No. 15, No. 16) to the throttle actuator
control motor (terminals No. 1, No. 2)

.

TECHNICAL DESCRIPTION

• ECM check whether the throttle actuator control

motor magneto has failed.
