Troubleshooting Primus IQ Brake Controller On 2006 Mitsubishi Pajero SUV

Question:

Hi, I have installed a primus IQ brake controller in my 2006 pajero np. Previous to installation all lights were working on the caravan. Have checked the wiring of the brake controller and all is correct as indicated by the display panel on the controller. With the engine idling I have the correct display of nc followed by .. on the controller so all seems to be correct, however when I hold the manual button full left and turn the wheel to indicate 6.0 I get nothing, the display stays on nc. any help would be appreciated. Kind Regards

The NC will be displayed on the controller if there is no trailer connected, when the manual override switch is adjusted. Per the instructions that should have been included with the brake controller, it states that if there is no trailer connected and the manual knob is activated, NC will be displayed. It appears as if the brake controller is working properly for you.
