Troubleshooting 
If you experience problems after installation, there is a simple test to help diagnose the problem. Simply 
unplug the wiring harness from the back of the Co-Pilot and put a bent paperclip into blue and yellow 
terminals of the harness’  plug  (jumper the blue and  yellow together).   This reconnects  the wire that 
you cut at the transmission plug and bypasses the Co-Pilot completely. 
If  your  pickup  behaves  normally  after  bypassing  the  Co-Pilot:    Make  sure  you  are  following  the 
operating instructions correctly and that all wire connection are good and to the proper wires.  If 
the problem  continues,  contact  our Technical Support  department  at  Tech@ATSDiesel.com or 
800-949-6002. 
If the problem continues after bypassing the Co-Pilot:  There is a problem with a wire connection. 
Double-check all connections.  Make sure your solder connections are good, if any look suspect, 
re-solder.    Make  absolutely  sure that  all  taps  were  made  on  the  correct  wires.    Some  of  these 
wires can be easily confused with neighboring ones especially if the connection was made away 
from the plug,  inside the wiring harness. If the problem continues, contact  our Technical 
Support department at Tech@ATSDiesel.com or 800-949-6002.
