STEP 5. Check for short circuit to ground between throttle 
actuator control motor connector B-05 (terminal No. 5) and 
PCM connector D-136 (terminal No. 141).
Q: Is the harness wire in good condition?

YES : Go to Step 6.
NO :  Repair it. Then go to Step 7.

STEP 6. Using scan tool MB991502, read the diagnostic 
trouble code (DTC).

CAUTION

To prevent damage to scan tool MB991502, always turn the 
ignition switch to the "LOCK"(OFF) position before con-
necting or disconnecting scan tool MB991502.
(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 P2102 set?

YES : Replace the PCM. Then go to Step 7.
NO :  It can be assumed that this malfunction is intermittent.

DIAGNOSTIC TROUBLE CODE PROCEDURES

13Ac-588

.

CIRCUIT OPERATION

• Controls the current that is applied from the PCM 

(terminals No. 133, No. 141) to the throttle actua-
tor control motor (terminals No. 5, No. 6).

.

TECHNICAL DESCRIPTION

• PCM varies the direction and the amperage of 

the current that is applied to the throttle actuator 
control motor in order to control the opening of 
the throttle valve.

.

DTC SET CONDITIONS

Check Conditions

• Battery positive voltage is higher than 8.3 volts

Judgement Criteria

• Throttle actuator control motor current is 8 

amperes 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.
