13-76Reverse Lockout System
Symptom Troubleshooting (cont’d)
REVERSE LOCKOUT SOLENOID 2P CONNECTOR
RVS (GRN/BLK)
NOTE: When checking if the transmission will shift to reverse while the wheels are being driven forward,
raise the vehicle on a lift, make sure it is securely
supported, and allow the front wheels to rotate freely.
 Do not release the clutch pedal if you can select reverse gear while the wheels are driven forward.
 When the vehicle is on a lift, and you make the wheels rotate, turn off the VSA system by the VSA
OFF switch.
1. Turn the ignition switch to LOCK (0).
2. Try to shift the transmission into reverse.
Go to step 4.
Go to step 3.
3. Do the reverse lockout solenoid test (see page 13-77).
Check the change lever assembly (see page
13-105), if necessary inspect the internal
transmission.
Repair or replace the reverse lockout solenoid
(see page 13-77).
4. Start the engine, and try to shift the transmission into reverse.
Intermittent failure, the system is OK at this
time.
Go to step 5. 5. Turn the ignition switch to LOCK (0).
6. Jump the SCS line with the HDS.
7. Disconnect ECM connector A (44P).
8. Disconnect the r
everse lockout solenoid 2P
connector.
9. Check for continuity between the reverse lockout solenoid 2P connector terminal No. 1 and body
ground.
Repair short to body ground in the wire
between the reverse lockout solenoid and the
ECM.
Check for loose terminals or poor connections
at the ECM. If necessary, update the ECM if it does
not have the latest software (see page 11-227), or
substitute a known-good ECM (see page 11-7), then
recheck. If the symptom goes away with a known-
good ECM, replace the original ECM (see page
11-228).

NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
 This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the
transmission.
1. Check for proper input shaft (mainshaft) speed sensor installation (see page 14-227).
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.

allow the front wheels to rotate freely, or raise the
vehicle on a lift.
5. Start the engine, disable the VSA by pressing the VSA OFF switch (if equipped), run the vehicle with
the shift lever in D at speeds over 20 km/h (12 mph)
for at least 10 seconds. Slow down and stop the
wheels.
6. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.
Go to step 7.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between the
input shaft (mainshaft) speed sensor and the PCM.
If the HDS indicates NOT COMPLETED, go to step 5. 7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
