6. ERROR CODES AND TROUBLESHOOTING 
On some occasions an error code may appear in the display. The following codes are 
available: 
Speed and distance indicate negative values 
If the values indicate negative values when driving ahead the reason is that the yellow 
wire is connected to a positive voltage. This is the case if a remote button is connected 
to yellow wire and it is quite normal. As soon as the remote button is defined to its 
desired functions the default function (reverse) is disabled and the minus sign 
disappeare. 
At speed C-giant stops counting for a while, shows ”C-rally” then works again 
The most probable reason is that the pulse rate from the speed sensor is too high. As a 
result the calibration value is over 100 000. The solution is to contact your dealer and 
replace the sensor interface or reduce the pulse rate to less than 10 pulses per meter 
(1600 per mile). 
A less likely reason is a bad connection for the power supply (plus as well as minus).
