Hey there folks,
Posting here in hopes that some of you may have knowledge that could save me a good few hours of troubleshooting. In the process of fixing some issues with my DOME circuit, I removed my RS3000 alarm system. After correcting all of my issues with that circuit, I noticed the following issues, most likely related to the wiring related to the Stop Light Switch from what I determined.
- Can't shift out of park without hitting manual release button.
- ABS warning light constantly on
- Combination meter backlight not working
- Brake lights DO work
Also probably related, the previous owner told me that the truck was broken into in the past and they made a mess hacking out wires in the drivers side kick panel, where a lot of the alarm and dome wires run. Everything worked upon purchase so I didn't pay it too much mind and still don't regret buying such an amazing vehicle, but when I started troubleshooting and removed the kick panel I revealed an absolute rats nest and hack job of a repair. Poorly crimped connections with several wires broken, zip tied and taped off in different directions. Took much longer than expected to fix everything thus far.
I'm hoping that this was caused by me cutting one wire that goes from the stop light switch, since it appears that all of my current issues are a part of this circuit. Worst case scenario I may have to run wires from the SLS to each individual component that it is tied into, listed below:
- ABS ECU
- ECT ECU
- Engine ECU
- CC ECU
- Shift lock ECU
Pictures of the relevant diagrams, if anyone has anything that I missed here that could probably help too, but checked both the FSM, electrical supplement, and RS3000 manual. Based on the diagrams its the Green-White wire coming off the SL switch going to each of the above ECUs. The electrical supplement manual shows the first four ECUs above but doesn't show the Shift lock ECU at all, which is instead shown in the big main FSM, it is kind of odd that the diagram shown in the FSM only shows the connections to the shift lock control ECU and none of the other components in the supplement...
Thanks in advance for all of your knowledge, I couldn't have fixed anything without you guys!
