I need to bring mine in and watch the tech go slowly insane as they try to figure out why the fast blinker is still going. I replaced my front turn indicators with LED. I wonder if an OBD2 diagnostic would figure that one out...I don't have much faith in the techs actually looking at the lights themselves...;DYou get the fast blinker sound inside the cab like you have a bulb out...that's how i found out.
@Willcuts93 do you have a little better pic of where this connector is located under the truck? I'd like to inspect mine myself.First is a continuity test of the tail light ground circuit. The covers for the connector are removed and the black wire, pin 20, is tugged on both sides to verify proper fitment. Then all wires in the center row on both male and female connectors are lightly tugged individually to verify they are fully engaged in place and the pin lock tabs are in place. If it passes it's reassembled. If it fails the connector is separated to inspect the pins for damage, the vehicle is then repaired as necessary with the required hardshell(s) and individual pins. Here's some neat pictures.
Damaged pin 20 lock on my truck
Broken hard shell on new in stock truck.
I've inspected 4 trucks today. 2 need hardshells with no pins and 2 passed inspection.
Hi Matt,I've inspected a total of 8 rangers now. Still only 2 require repair.
