Driver can select reverse gear when vehicle speed is 12 mph (20 km/h) or more

WARNING: This page is about a different variant/trim than selected.

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.
Refer to How to Troubleshoot Circuits at the ECM connectors in the Fuel and Emissions Systems section before troubleshooting this circuit (see HOW TO TROUBLESHOOT CIRCUITS AT THE ECM/PCM CONNECTORS ).

Turn the ignition switch to LOCK (0).
Check the No. B12(10A)fuse in the under-dash fuse/relay box.
Is the fuse OK?

YES -Reinstall the fuse, then go to step 3.

NO -Install a new No. B12 (10 A) fuse, and recheck. If the fuse continues to blow, check for short to body ground on the No. B12 (10 A) fuse circuit.
Test-drive the vehicle.
Check for fuel and emissions system's DTCs with the HDS.
Are there any DTCs stored in the ECM?

YES -Go to the indicated ECM DTCs troubleshooting.

NO -Go to step 5.
Turn the ignition switch to LOCK (0).
Disconnect the reverse lockout solenoid 2P connector.
Turn the ignition switch to ON (II).
Measure the voltage between reverse lockout solenoid 2P connector terminal No. 1 and body ground.

Is there battery voltage?

YES -Go to step 9.

NO -Repair an open in the wire between No. B12 (10 A) fuse in the under-dash fuse/relay box and the reverse lockout solenoid.
Turn the ignition switch to LOCK (0).
Jump the SCS line with the HDS.
Disconnect ECM connector A (44P).
Check for continuity between reverse lockout solenoid 2P connector terminal No. 2 and ECM connector A (44P) terminal No. 27.

Is the continuity?

YES -Go to step 13.

NO -Repair an open in the wire between the reverse lockout solenoid and the ECM.
Do the reverse lockout solenoid test (see REVERSE LOCKOUT SOLENOID TEST ).
Is the reverse lockout solenoid OK?

YES -Check for loose terminals or poor connections at the ECM. If necessary, update the ECM if it does not have the latest software (see ELD REPLACEMENT ), or substitute a known-good ECM (see SUBSTITUTING THE ECM/PCM ), then recheck. If the symptom goes away with a known-good ECM, replace the original ECM (see ECM/PCM REPLACEMENT ).

NO -Repair or replace the reverse lockout solenoid (see REVERSE LOCKOUT SOLENOID DISASSEMBLY/REASSEMBLY ).
