STEP 46. Check the transmission range switch.
Measure the resistance between the terminals for each selec-
tor position as indicated in the table below.

NOTE: For vehicles with sport mode, four positions (P, R, N, D) 
are used.
Q: Is the measured resistance less than 2 ohms for each 

selector position?
YES : Go to Step 47.
NO :  Replace the transmission range switch. Refer to 

GROUP 23B, Transaxle 

P.23B-10

.

STEP 47. Check transmission range switch connector B-41 
for loose, corroded or damaged terminals, or terminals 
pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 48.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 48. Measure the transmission range switch output 
voltage at PCM connector C-61 by backprobing.
(1) Do not disconnect connector C-61.
(2) Turn the ignition switch to the "ON" position.
(3) Move the selector lever to the "L" position.

(4) Measure the voltage between terminal 110 and ground by 

backprobing.

• The voltage should measure battery positive voltage.

(5) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Does the voltage measure battery positive voltage?

YES : Go to Step 13.
NO :  Go to Step 49.

STEP 49. Check PCM connector C-61 for loose, corroded 
or damaged terminals, or terminals pushed back in the 
connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 50.
NO :  Repair or replace the damaged components. Refer to 

GROUP 00E, Harness Connector Inspection

STEP 50. Check harness for open circuit or short circuit to 
ground between transmission range switch connector 
B-41 terminal 6 and PCM connector C-61 terminal 110.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair or replace the harness wire.

STEP 51. Check PCM connector C-61 <2.4L Engine> or 
C-63 <3.0L Engine> and shift switch assembly connector 
C-65 for loose, corroded or damaged terminals, or 
terminals pushed back in the connector.
Q: Are the connector and terminals in good condition?

YES : Go to Step 52.
NO :  Repair or replace the damaged components. Refer to

STEP 52. Check harness for short circuit to ground 
between shift switch assembly connector C-65 terminal 5 
and PCM connector C-61 <2.4L Engine> or C-63 <3.0L 
Engine> terminal 109.
Q: Is the harness wire in good condition?

YES : Go to Step 5.
NO :  Repair or replace the harness wire.
