STEP 4. Check harness for open circuit or short circuit to
ground between Park/Neutral position switch connector B-
41 terminal 8 and junction block connector C-107 terminal
12 <Vehicles with sport mode> or terminal 9 <Vehicles
without sport mode>.
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair it.
STEP 5. Using scan tool MB991502, check data list item 61:
Park/Neutral Position Switch.
CAUTION
To prevent damage to scan tool MB991502, always turn the
ignition switch to "LOCK" (OFF) position before
connecting or disconnecting scan tool MB991502.
(1) Connect scan tool MB991502 to the data link connector.
(2) Turn the ignition switch to "ON" position.
(3) Set scan tool MB991502 to data reading mode for item 61:
Park/Neutral Position Switch.
•
Move the selector lever to "P," "R," "N," "D," "3," "2," "L"
and sport mode positions to confirm whether the MUT-II.
(The sport mode is indicated as "D" on the MUT-II.)
(4) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the switch operating properly?

Check for continuity between terminals for each selector
position.
NOTE: For vehicles with sport mode, four positions (P, R, N, D)
are used.
Q: Is the switch operating properly?
YES : Go to Step 7.
NO : Replace the Park/Neutral position switch. Refer to
GROUP 23B, Transaxle
.
STEP 7. Check connector B-41 at the Park/Neutral position
switch for damage.

STEP 8. Check the switch output voltage at PCM
connector C-61 <2.4L Engine> or C-63 <3.0L Engine> by
backprobing.
(1) Do not disconnect connector C-61 <2.4L Engine> or C-63
<3.0L Engine>.
(2) Turn the ignition switch to "ON" position.
(3) Move the selector lever to "P" position.
(4) Measure the voltage between terminal 101 and ground by
backprobing.
•
Voltage should be battery positive voltage.
(5) Turn the ignition switch to "LOCK" (OFF) position.
Q: Is the voltage normal?
YES : Go to Step 12.
NO : Go to Step 9.
STEP 9. Check connectors C-61 <2.4L Engine> or C-63
<3.0L Engine> at PCM for damage.
Q: Is the connectors in good condition?
YES : Go to Step 10 <Vehicles with sports mode>. Repair it
because of the harness open circuit or short circuit to
ground between Park/Neutral position switch
connector B-41 terminal 3 and PCM connector C-61
<2.4L Engine> or C-63 <3.0L Engine> terminal 101.
<Vehicles without sports mode>
NO : Repair or replace it. Refer to GROUP 00E, Harness
