GENERAL TROUBLESHOOTING
Normal Operation
Your Derringer Tuner has a built-in, self-diagnostic
system. The status of the Derringer system is
communicated via the LED on the module. When the
Derringer Tuner is functioning properly the LED will flash
green.
Derringer Not Powered
When the LED is not illuminated, the Derringer Tuner is
not powered on. If the ignition is on and the LED is not
illuminated, check the TMAP connections on the vehicle
and ensure they are fully engaged.
No Communication with iDash 1.8
Check that your wiring matches the figure in Section
1.1 Derringer Tuner System Configuration: 1.2.2
iDash 1.8" Config. (See page 10-11) or for multiple
iDash 1.8 Gauges see Figure 1.3-14 on page 18.
Common sources of communication errors are wrong
caps attached to the Derringer and/or the In-Cab
Termination Cable is not installed. A Black Termination
Cap must be connected to the Derringer and only one
In-Cab Termination Cable should be attached to one of
the iDash 1.8's.
LED Error Code
When faults are detected, the Derringer Tuner will
flash a diagnostic code. These diagnostic codes are
comprised of 2 digits. Each digit is expressed by the
flashing red LED.
A code can be determined by counting the number of red flashes displayed before
the LED flashes green for the first digit and the number of red flashes after the
LED flashes green for the second digit. After the diagnostic code is displayed,
additional codes will be displayed in sequence, separated by 4 seconds with the
LED off. Once all codes are displayed the Derringer will begin sending the codes
again. Once you have written down all diagnostic codes being displayed, consult
the following tables for a description of the code along with the action to be taken.
Bypass Plug
If the Derringer should ever need to be removed from the vehicle, the system
includes a bypass plug that must be connected to the sensor harness in place
of the module. Failure to utilize the bypass plug when the Derringer has been
unplugged from the harness will generate a Check Engine light when attempting to
start the vehicle.
