STEP 6. Check harness for open circuit or short circuit to
ground between shift switch assembly connector C-65
terminal 3 and junction block connector C-107 terminal 9.
Q: Is the harness wire in good condition?

YES : Go to Step 3.
NO : Repair it.

STEP 7. 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.

•

The scan tool should display "D" when the selector lever
is "D" range.

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

Q: Is the switch operating properly?

YES : Go to Step 8.
NO : Go to Step 15.

STEP 8. Check the shift switch assembly.
Refer to

P.23A-351

, Transaxle Control.

Q: Is the switch operating properly?

YES : Go to Step 9.
NO : Replace the shift switch assembly. Refer to

STEP 9. Check connector C-65 at shift switch assembly for
damage.
Q: Is the connector in good condition?

YES : Go to Step 10.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

.

STEP 10. Check the power supply voltage at shift switch
assembly connector C-65.
(1) Disconnect connector C-65 and measure at the harness

side.

(2) Turn the ignition switch to "ON" position.
(3) Selector lever position should be "D" range.

(4) Measure the voltage between terminal 1 and ground.

•

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 11.

STEP 11. Check connector B-41 at Park/Neutral position
switch for damage.
Q: Is the connector in good condition?

YES : Repair it because of harness open circuit between

shift switch assembly connector C-65 terminal 1 and
Park/Neutral position switch connector B-41 terminal
3.

NO : Repair or replace it. Refer to GROUP 00E, Harness

STEP 12. 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) Selector lever position should be sport mode.

(4) Measure the voltage between terminal 109 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 14.
NO : Go to Step 13.

STEP 13. Check connectors C-61 <2.4L Engine> or C-63
<3.0L Engine> at PCM connector for damage.
Q: Are the connectors in good condition?

YES : Repair it because of harness open circuit or short

circuit to ground between shift switch assembly
connector C-65 terminal 4 and PCM connector C-61
<2.4L Engine> or C-63 <3.0L Engine> terminal 109.

NO : Repair or replace it. Refer to GROUP 00E, Harness
