IX. Control Box Troubleshooting
Stuck Button
When the Control Box is first turned on, all buttons are checked to verify that a button is not stuck on. If a button is
detected to be on during power up, the button will be disabled and the following message will be displayed until
another button is pressed. To verify if a button really is stuck on, re-power the box without pressing any buttons.
Button is Stuck!
Note: A common problem is a bad ground connection on the sled causing the box to keep resetting itself. If a button
is being pressed when this occurs, the “button stuck” message will be displayed. Start the sled without pressing a
button and see if the message goes away. If it is not present, start looking for a disconnected ground on the sled (see
Other Issues below).
If a button really is stuck on, the Control Box can still function and adjust fuel properly. The Control Box can be sent
back to Boondocker to be serviced.
Injector Fault
The Control Box monitors the signals from the sled’s ECU. If it detects signals on one set of wires but not the other, it
will detect a fault on that injector and display one of the two error messages.
Injector 1 Fault!
Missing or bad signal detected on Injector #1 (yellow wire).
Injector 2 Fault!
Missing or bad signal detected on Injector #2 (green wire).
Injector 3 Fault!
Missing or bad signal detected on Injector #3 (blue wire).
Injector 4 Fault!
Missing or bad signal detected on Injector #3 (pink wire).
Injector x Fault!
This means a previous injector fault has occurred which has not yet been
cleared. (Press any button when error message is displayed to clear the fault)
If any of these conditions occur, the Control Box will still function and it will still try to make fuel adjustments, but
the intermittent injector connection will need to be fixed. Contact Boondocker to determine if the Control Box and
harness need to be sent back to be inspected or serviced.
Note 1: Injector errors that occur infrequently can be ignored since they are likely caused by sporadic electrical noise.
Note 2: It is possible for the sled to run but the wiring harness to be wrong – the box cannot make proper fuel
adjustments. If you see an injector error, first recheck the wire positions in the black connectors according to
the tables in these instructions.
Other Issues
Engine runs erratically:
1. Verify that the ground on the sled’s harness has a good connection to the chassis.
2. Verify that the EFI Harness Ground Wire has a good connection.
3. Verify that all wiring is in good condition and that the wires have not pulled out of the terminals. To verify this,
look inside each connector and verify that the terminal pins are all at the same height. If a terminal is starting to
