STEP 6. 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 P2101 set?
YES : Replace the PCM. Then go to Step 7.
NO : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
STEP 7. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
(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 P2101 set?
YES : Retry the troubleshooting.
NO : The inspection is complete.

DTC P2102: Throttle Actuator Control Motor Circuit (shorted Low)
.
CIRCUIT OPERATION
• Controls the current that is applied from the PCM
(terminals No. 147, No. 141) to the throttle actua-
tor control motor (terminals No. 1, No. 2).
.
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.

.
TROUBLESHOOTING HINTS (The most likely
causes for this code to be set are:)
• Throttle actuator control motor failed.
• Shorted throttle actuator control motor circuit or
connector damage.
• PCM failed.
DIAGNOSIS
Required Special Tools:
• MB991958: Scan tool (MUT-III Sub Assembly)
• MB991824: V.C.I.
• MB991827: USB Cable
• MB991910: Main Harness A
STEP 1. Check harness connector B-06 at throttle actuator
control motor for damage.
Q: Is the harness connector in good condition?
YES : Go to Step 2.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection
. Then go to Step 7.
