STEP 24. Check the shift switch assembly.
Refer to

P.23A-351

, Transaxle Control.

Q: Is the switch operating properly?

YES : Go to Step 25.
NO : Replace the shift switch assembly. Refer to

P.23A-

349

, Transaxle Control.

STEP 25. Check connector C-65 at the shift switch
assembly for damage.
Q: Is the connector in good condition?

YES : Go to Step 26.
NO : Repair or replace it. Refer to GROUP 00E, Harness

Connector Inspection

P.00E-2

.

STEP 26. Check the switch output voltage at PCM
connector C-61 <2.4L Engine> or C-63 <3.0L Engine>.
(1) Disconnect connector C-61 <2.4L Engine> or C-63 <3.0L

Engine> and measure at the harness side.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 122 and ground.

•

Voltage should be battery positive voltage when the
selector lever is upshift and hold.

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

Q: Is the voltage normal?

YES : Go to Step 14.
NO : Go to Step 27.

STEP 30. Check the switch output voltage at PCM
connector C-61 <2.4L Engine> or C-63 <3.0L Engine>.
(1) Disconnect connector C-61 <2.4L Engine> or C-63 <3.0L

Engine> and measure at the harness side.

(2) Turn the ignition switch to "ON" position.

(3) Measure the voltage between terminal 110 and ground.

•

Voltage should be battery positive voltage when the
selector lever is downshift and hold.

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

Q: Is the voltage normal?

YES : Go to Step 14.
NO : Go to Step 31.

STEP 31. 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 8 and PCM connector C-61
<2.4L Engine> C-63 <3.0L Engine> terminal 110.

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