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)
Set scan tool MB991958 to the data reading mode for item
11, Accelerator Pedal Position Sensor (main).
⦆
Output voltage is between 0.9 and 1.1 volts when foot is
released from accelerator pedal.
⦆
Output voltage is 4.0 volts or higher when accelerator
pedal is fully depressed.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is the sensor operating properly?
YES:
Go to Step 4.
NO:
Replace the accelerator pedal position sensor. Then
go to Step 4.
STEP 4. 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)
Read the DTC again.
(4)
Turn the ignition switch to the "LOCK" (OFF) position.
Q:Is DTC P2122 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.
NO:
It can be assumed that this malfunction is
