Co-Pilot Troubleshooting

Managing your Co-Pilot Settings

Having trouble setting up your Co-Pilot or aren't sure of the correct settings for your vehicle? Check here first for some tips on correct installation. Running your Co-Pilot should be simple and problem free, but should you run into any issues we've got a few tricks to get you back up and running. Below, we've got a run-down on the settings for your Co-Pilot and what they control.

Getting into the Settings Menu: With the Co-Pilot on, hold down the MENU button for 5 seconds. Once at the settings menu, you can scroll through the options by using the MODE button. To change values in these settings use the Up and Down Arrow buttons. Hit the MODE button in order that your changes will be saved. To return from the Settings menu, simply hit the MENU button again.

Flush Delay: This setting controls the length of time you purge your system before shutdown. The length of time for a proper purge will depend on the particular vehicle and setup, but 30 seconds is a good all-around standard. Changes can be made using the up and down arrows. Save setting using the MODE button.

Engine Temp High: This is the temperature setting for your coolant to switch to Vegetable Oil while running in AUTO mode (in manual mode, you will hear a beep at this temp). Once your coolant temp hits this temp, your valves will switch and start running your vehicle on vegetable oil.

Engine Temp Low: If your engine dips too low, your Co-Pilot will employ this safety measure, purging your system and automatically switching back to diesel. Although a rare occurrence, it can save you if you start losing coolant. Be sure not to set this temperature higher than your engine temp high, or your Co-Pilot will not function correctly in Auto Mode. We recommend keeping this temp setting below 120.

Oil Temp High: Contrary to what it may seem, this setting does not affect when your vehicle switches over to running on vegetable oil (switchover is controlled by Engine Temp High setting based on coolant temperature). This setting is for the thermostatic control over an auxiliary electric heater. This is the high temp shutoff for such an electric heater, though it is worth reiterating that if one were to use an electric heater they must use a relay (not powered directly from Co-Pilot).

Oil Temp Low: This is the minimum temp for switching on the electric heater relay trigger (will only turn on in Veg mode).

Fuel Level High: This is the highest reading on the tank level for vegetable oil. To set this, you should fill your tank and see what the sensor is reading. The Co-Pilot will only read full bars if you set your level high 1 below this level (if your sensor max is 8, set your level high to 7).

Fuel Level Low: Set your fuel level low to either 1 or 0. Setting this to 1 will give you a decent reserve and will show zero bars at the lowest sensor reading. Setting it to 0 will show zero bars once the level dips below the lowest level reading on your sender. All of our level senders sit 1/2" above the bottom of your tank, so this will still give you some reserve.

Pump Type: Unless you are running plastic motor driven valves, your Pump Type should always be set to Pump Type A (this is the proper setting for all solenoid style valves). Should you be using motor driven valves with your Co-Pilot, you will also require a DPDT relay setup in order to properly control your valves.

Backlight Level: The settings for the backlight are slightly counter-intuitive in that the higher the number, the lower the level of backlight. The brightest setting is 0, with no backlighting at 255.

Common Co-Pilot Issues

We do our best to provide a problem-free unit however simple connection issues and power fluctuations can cause glitches to occur . Here are some of the common issues and the best solutions for you should this happen.

Co-Pilot Turning off while driving: This is almost always an intermittent power problem to the Co-Pilot. Most often, it is the switched 12v ignition source (yellow wire) losing connection over time, causing the Co-Pilot to shut down. Check the red and brown wires for proper connection to the battery as well. This could also be a problem with the connection on your usb cable, described below.

Oil/Engine Temp Reading LOW Constantly: Check your connections to the temperature senders, including the black ground wires to make sure that one of the blade terminals has not fallen off.

Not Switching Over in AUTO Mode: This could be due to incorrect settings from changes in the config menu, or a bad connection to one of the temperature senders. Check wiring to the temp senders as described above, and try resetting back to factory settings on the Co-Pilot as described on the previous page.

'Cable Error' Reading on Co-Pilot: These units are sensitive to large fluctuations in voltage, so be sure to disconnect the battery connections when changing out your alternator or battery, as these will cause the cable error reading. If this does happen, disconnect the Co-Pilot battery connections for a few minutes, then try starting up your Co-Pilot again.

Low Power To Display/ Error Messages: The USB cable connection to your display unit can become damaged if the cord is pulled on too much or if you bend or hit the cord while it is connected to the display box. Generally, this will damage the plastic locating pin on the display box connector. This is what holds the wires in place for a proper connection, so if you damage and loose the pin you will not have a proper connection to the display box. A connector with the pin intact is shown on the right.
