STEP 18. Measure 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 the "ON" position.

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

• The voltage should measure battery positive voltage 

when the selector lever is upshift and hold.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 21.
NO :  Go to Step 19.

STEP 19. Check PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> and shift switch assembly connector 
C-65 for looser, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Are the connectors and terminals in good condition?

YES : Go to Step 20.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection 

P.00E-2

STEP 20. Check the harness for open circuit or short 
circuit to ground between PCM connector C-61 <2.4L 
Engine> or C-63 <3.0L Engine> terminal 122 and shift 
switch assembly connector C-65 terminal 3.
Q: Is the harness wire in good condition?

YES : Go to Step 4.
NO :  Repair or replace the harness wire.

STEP 21. Check PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> for looser, corroded or damaged 
terminals, or terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 4.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

.

STEP 22. Check the shift switch assembly.
Refer to 

P.23A-420

, Transaxle Control.

Q: Is the switch operating properly?

YES : Go to Step 23.
NO :  Replace the shift switch assembly. Refer to 

P.23A-418

, Transaxle Control.

STEP 23. Measure 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 the "ON" position.

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

• The voltage should measure battery positive voltage 

when the selector lever is downshift and hold.

(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the measured voltage battery positive voltage?

YES : Go to Step 26.
NO :  Go to Step 24.

STEP 24. Check PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> and shift switch assembly connector
