Depowering the SRS system - from the 2015 Service Manual:
501-20B Supplemental Restraint System 2015 F-150
General Procedures Procedure revision date: 09/27/2013
Supplemental Restraint System (SRS) Depowering
Depower
WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
1. WARNING: Before beginning any service procedure in this section, refer to Safety Warnings in section 100-00 General Information. Failure to follow this instruction may result in serious personal injury. Refer to: Health and Safety Precautions (100-00 General Information, Description and Operation).
2. Determine if a SRS fault is present. Turn the ignition OFF and wait 10 seconds, then turn the ignition ON and monitor the airbag warning indicator. The airbag warning indicator illuminates continuously for approximately 6 seconds and then turns off. Continue to monitor the airbag warning indicator for approximately 30 seconds as this is the time required for the RCM to complete testing of the SRS.
3. If a SRS fault is present the airbag warning indicator either fails to light, remains lit continuously or flashes. The flashing may not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. If this occurs, diagnose and repair any SRS faults before proceeding with other repairs.
If after the ignition has been turned ON for 30 seconds the airbag warning indicator remains unlit with no chime or SRS message displayed in the message center, no SRS fault is present.
If the airbag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps or a message displays in the message center. If this occurs, diagnose and repair the airbag warning indicator and any SRS faults before proceeding with other repairs.
No SRS Fault Present (with ignition ON, airbag warning indicator stays off after prove out)
4. WARNING: Turn the ignition OFF and wait one minute to deplete the backup power supply. Ignition must remain OFF until repair is complete. Failure to follow this instruction may result in serious personal injury or death in the event of an accidental deployment. Turn the ignition OFF and wait one minute before continuing vehicle service.
SRS Fault Present
5. Turn the ignition OFF.
6. Remove the RCM fuse. Refer to Wiring Diagram Cell 11/Section 700-01 for fuse and relay information.
7. Turn the ignition ON.
8. Using a diagnostic scan tool, carry out a Network Test. Verify that the RCM does not respond to the Network Test. If the RCM passes the Network Test, remove the correct RCM fuse and repeat the Network Test to verify before proceeding.
9. Turn the ignition OFF.
10. Disconnect the battery.
Refer to: Battery Disconnect and Connect (414-01 Battery, Mounting and Cables, General Procedures).
11. Wait at least one minute before continuing vehicle service.
That ^^ and make sure you're inserting it at the correct angle/direction. It should be a very snug fit but not impossible to insert. You might try turning the clip (plug in) 180* to make sure you're inserting it correctly. I wouldn't force it. You should feel it sliding.
I'm having a hard time pushing 9, 10, 11 pins far enough into connector C226. Any advice or suggestions? Am I doing it completely wrong? haha
please check pin orientation. ....they are to only be inserted one way. Should look identical to the pins already in the harness.....when inserting. As stated above, if it's difficult to insert, it is perhaps 180 degrees out. When inserted correctly it will slide in with only a little resistance and click/lock into place.
I just wanted to formally thank i8iridium and BGG for making this work out for myself and everyone else. I couldn't have done it without you. Honestly, I never even used select shift before but I'm definitely enjoying this now. So to both of you, thank you!
Add another column shifter to the complete list! Many thanks go out to BGG for the harness and everyone who took pictures and identified the correct wiring!
No worries...it was myself and Livnitup that figured out how to get this working, i8irdium for the super....SUPER awesome write up, and Dan for a few critical pics from his Raptor to confirm a few things that we speculated but needed to double check. Very pleased this is still being received aND sought after. I know 1st hand that we have more than 20 members that have joined our forum because of this mod. How do I know???, lol because they joined to PM me about the harness! Way cool! Love how it helps the forum grow too!
almost finished with oem halogen wiring to oem LED wiring for the headlights. More testing and then will hand off to Livnitup to verify.
