DIAGNOSIS

Required Special Tools:

｠

MB991958: Scan Tool (M.U.T.-III Sub Assembly)

｠

MB991824: V.C.I.

｠

MB991827: USB Cable

｠

MB991910: Main Harness A

STEP 1. Check harness connector B-08 at throttle actuator
control motor and harness connector B-10 at ECM for
damage.

Q:Is the harness connector in good condition?

YES:

 Go to Step 2.

(1)

Disconnect the connector B-08.

(2)

Measure  the  resistance  between  throttle  actuator  control
motor side connector terminal No. 1 and No. 2.

Standard value: 0.3 - 80 Ω [at 20°C (68°F)]

Q:Is the measured resistance between 0.3 and 80 ohms [at

20°C (68°F)]?

YES:

 Go to Step 3.

NO:

 Replace the throttle body assembly. Then go to Step

5.

STEP 3. Check for short circuit to ground between throttle
actuator control motor connector B-08 and ECM connector
B-10.

To prevent damage to scan tool MB991958, always turn the
ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting 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)

Read the DTC again.

(4)

Turn the ignition switch to the "LOCK" (OFF) position.

Q:Is DTC P2101 set?

YES:

 Replace the ECM. When the ECM is replaced, register

the ID code. Refer to GROUP 42B, ID Code Registration
Judgment Table <Vehicles with KOS> P.42B-12or GROUP
42C, ID Code Registration Judgment Table <Vehicles with
WCM> P.42C-8. Then go to Step 5.

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.

DIAGNOSTIC TROUBLE CODE PROCEDURES

STEP 5. 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.

CIRCUIT OPERATION

｠

A 5-volt power supply is applied on the accelerator
pedal  position  sensor  (main)  power  terminal
(terminal No. 1) from the ECM (terminal No. 75).
The ground terminal (terminal No. 2) is grounded
with ECM (terminal No. 76).

TECHNICAL DESCRIPTION

｠

The  accelerator  pedal  position  sensor  (main)
outputs  voltage  which  corresponds  to  the
accelerator pedal depression.

｠

The  ECM  checks  whether  the  voltage  is  within  a
specified range.

DESCRIPTIONS OF MONITOR METHODS

Accelerator  pedal  position  sensor  (main)  output
voltage is out of specified range.
