DIAGNOSTIC TROUBLE CODE PROCEDURES

13Ac-577

STEP 8. Using scan tool MB991502, read the diagnostic
trouble code (DTC).
(1) Connect scan tool MB991502 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.

DIAGNOSTIC TROUBLE CODE PROCEDURES

13Ac-578

.

TECHNICAL DESCRIPTION

• PCM check whether the throttle actuator control

motor magneto has failed.

.

DTC SET CONDITIONS

Check Condition

• Battery positive voltage is higher than 8.3 volts.

Judgement Criteria

• The coil temperature of the throttle actuator con-

trol motor should be 180

°C (356°F) or higher for

0.16 seconds.

.

TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)

• Throttle actuator control motor failed or malad-

justed.

• Open or shorted throttle actuator control motor

circuit, or loose connector.

• PCM failed.

DIAGNOSIS

Required Special Tool:

• MB991502: Scan Tool (MUT-II)

STEP 1. Check connector B-05 at throttle actuator control
motor for damage.
Q: Is the 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 7.

STEP 2. Check the throttle actuator control motor.
(1) Disconnect the connector B-05.

(2) Measure the resistance between throttle actuator control

motor side connector terminal No. 5 and No. 6.

Standard value: 0.3

− 100 ohms

Q: Is the measured resistance between 0.3 and 100 ohms?

YES : Go to Step 3.
NO : Replace the throttle body ASSY. Then go to Step 7.

STEP 3. Check connector D-136 at PCM for damage
Q: Is the connector in good condition?

YES : Go to Step 4.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

. Then go to Step 7.

STEP 4. Check for short circuit to ground and harness
damage between throttle actuator control motor connector
B-05 (terminal No. 6) and PCM connector D-136 (terminal
No. 133).
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO : Repair it. Then go to Step 7.
