Customer Question

We have a International box truck 4300 and the running lights are not working? He has tail lights and head lights. I read on an old forum and he is checking the brown and blue plug, if not that what could it be?

I got the wiring diagrams but was really hoping for an easier fix than that. The truck has headlights and breaklights, but has not track lights or taillights. Any ideas?
Expert:  Daniel Wilson replied 1 year ago.
So you are looking for a diagnosis without testing the circuit following the diagrams? Or someone to walk you through each step of the test process?
Expert:  Daniel Wilson replied 1 year ago.
do you have any body controller codes logged in the dash? do you know how to access them? If not let me know
Customer: replied 1 year ago.
We looked up on You Tube to get codes will let you know what it shows. My womanly brain can google but not read wiring diagrams, lol
Expert:  Daniel Wilson replied 1 year ago.
I understand. If I didnt choose this as a profession Id be in the same boat so no worries. Post all numbers and spaces in between for the fault codes.

611 14 5 1 4007/Bus 1603 D Connector #4007 Pin #D Low beam under current The current from this output is below 0.5 A Open circuit Refer to Headlight System in the Light Systems section of this manual. 611 14 4 2 4007/Bus 1603 H Connector #4007 Pin #H Park light over current The output behaves like a 20 amp type III circuit breaker. Short to ground or overload Refer to Marker, Park and Tail Lamps in the Light Systems section of this manual. These two are for your lights. The connector numbers are listed in the description and the pin that is showing trouble in the connector. In the diagrams I posted you or your mechanic will need to test the circuit using the schematics I posted and these codes tell you what connector pin and part of the harness to test.
