2. Push both buttons on the remote.
3. Parklights will flash 15 times.
4. Turn the switch back on.
Try your remote start, The unit may be in tach lockout mode
Hope this works, not sure what Command start you have.
There is an on/off switch. Should be a silver toggle switch under the dash somewhere. Sometimes they are not marked so flip the switch and try the starter. To find the switch follow the red wire from the smaller harness to the switch. One wire from the switch hooks to the red wire, the other wire from the switch hooks to ground. When the switch is off only the locks work.
