2011年9月2日 · You've checked the grounds (Pins 4 & 5) on the DLC and they are good. You've checked for power at Pin 16 of the DLC and no joy. Is all that correct? Is there power at the Cigar Lighter in the ashtray? If yes, you've got a problem between connector C204 (behind ashtray) and the DLC (light Blue wire with White trace).

2022年3月6日 · The bottom row begin with #9 from the left, and end with #16 on the right. Inspect this DLC connector and its pins for any signs of damage. Remove PCM connector C1381a and inspect it and its pins for any signs of damage. Pins 13 and 14 are the pins that go to the DLC connector (CAN PLUS and CAN MINUS)

2020年4月21日 · OBDII port (DLC connector) does not connect to scan tool or to tuner (no communication at obd2 port, also can be a crank no-start) Check fuse #12 (cigar lighter fuse - 20 AMP mini fuse).

2016年3月13日 · Found the connector. On my truck, it's clipped to a cross bar at the back bottom of the glove box. The glove box is really easy to remove: Open it, then tug the back corners in one at a time to release the stops, then open some more and pull toward the back of the truck to disengage the hinges. Once the glove box is off, you can see the connector.

2023年1月3日 · The GPCM was good after I cleaned all the connections. I had a no start after that for a minute that was caused by having the IPR and ICP connector disconnected at the same time. IPR connector was fixed and hooked up and now im running again. Running rough since i need to install the new ICP connector but its in a way better position now.

2012年6月5日 · Patrick, thank you for the info on a 1994 F-250 7.3 IDI. I traced all the designated color leads closely in the C138, 12 pin connector. The red with black trace coming from the water-in-fuel sensor on the fuel filter the best I can tell passes through a C1047M/C1047F connector (circuit 327) not the C138 12 pin connector initially.

2023年5月23日 · Can’t pull any codes – power to DLC, but no comms. Tried three different scanners. Pulled PCM and tested pins 71,97 for KO 12v power – good. Pin 55 12v constant- good. NO GROUND on pins 25,51,77 and 103. I’m guessing my problem with lack of coms on DLC and Crank no start are related to no ground at PCM connector.

2013年4月19日 · I checked the big block connector lunk that runs under the intake hose over the valve cover and disconnected it and found moisture in there so i sprayed some wd-40 and put dielectric grease as well as idm connector and buttoned them back up. After all this there is still no change and no WTS light. all other lights come on including SES light.

2017年5月30日 · The wiring can literally be anywhere. I'm sorry, I'm not that familiar with PCI, it's an older stranded and not really used anymore, but that wire basically goes to all kinds of different places. But there will be several buses, thats why there are several listed in that connector legend.

2021年5月28日 · Can you get ANY engine data from the data link connector (DLC)? Look for EOT or ECT or rpms. If you can get that data, then I would say you have a FICM issue. Have you verified that the FICM X3 connector (C1388C) is solidly plugged in (X-3 is a wider plug than the other two and is nearest the degas bottle)
