• MB991910: Main Harness A

STEP 1. 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) Read the DTC.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the diagnostic trouble code other than P060D set?

YES : Refer to Diagnostic Trouble Code Chart

P.13B-50

.

NO : Go to Step 2.

STEP 2. Using scan tool MB991958, check data list.
(1) Turn the ignition switch to the "ON" position.
(2) Check the following item in the data list. Refer to Data List

Reference Table

P.13B-836

.

a. Item 11: Accelerator pedal position sensor (main)
b. Item 12: Accelerator pedal position sensor (sub)

(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the sensor operating properly?

YES : Go to Step 3.
NO : Repair or replace it. Then go to Step 4.

STEP 3. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
(1) Turn the ignition switch to the "ON" position.
(2) After the DTC has been deleted, read the DTC again.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P060D set?

YES : Replace the ECM. When the ECM is replaced,

register the ID code. Refer to GROUP 42B, Diagnosis
− ID Codes Registration Judgment Table <Vehicles

with KOS>

P.42B-15

or GROUP 42C, Diagnosis

.

STEP 4. Using scan tool MB991958, read the diagnostic
trouble code (DTC).
(1) Turn the ignition switch to the "ON" position.
(2) Read the DTC.
(3) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is DTC P060D set?

YES : Retry the troubleshooting.
NO : The procedure is complete.
