STEP 12. Check harness for short circuit to ground
between transmission range switch connector B-41
terminal 3 and combination meter connector C-43 terminal
11. <Vehicles with sport mode>
Q: Is the harness wire in good condition?
YES : Go to Step 5.
NO : Repair or replace the harness wire.
STEP 13. Check PCM connector C-61 <2.4L Engine> or
C-63 <3.0L Engine> 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 5.
NO : Repair or replace the damaged components. Refer to

STEP 14. 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 15.
NO : Replace the transmission range switch. Refer to
GROUP 23B, Transaxle
STEP 15. 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 16.
NO : Repair or replace the damaged components. Refer to
GROUP 00E, Harness Connector Inspection

STEP 16. Measure the transmission range 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 the "ON" position.
(3) Move the selector lever to the "R" position.
(4) Measure the voltage between terminal 108 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 17.
STEP 17. Check PCM connector C-61 <2.4L Engine> or
C-63 <3.0L Engine> 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 18.
NO : Repair or replace the damaged components. Refer to

STEP 18. Check harness for open circuit or short circuit to
ground between transmission range switch connector
B-41 terminal 7 and PCM connector C-61 <2.4L Engine> or
C-63 <3.0L Engine> terminal 108.
Q: Is the harness wire in good condition?
YES <Vehicles without sport mode> : Go to Step 5.
YES <Vehicles with sport mode> : Go to Step 19.
NO : Repair or replace the harness wire.
STEP 19. Check intermediate connector C-27 and
combination meter connector C-43 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector. <Vehicles with sport mode>
Q: Are the connectors and terminals in good condition?
YES : Go to Step 20.
NO : Repair or replace the damaged components. Refer to
