Hey all,
I've been having a lot of "fun" with my '09 1500 5.7. I figured I'd toss a line out and see if anybody had any recommendations of what to look at first before I start probing all my wires.
Ever since I got my Ram last year (Body bought at auction due to a blown engine (~259,000 km). Swapped with a 2010 5.7 with around 200,000 km on it), I've had some odd issues that's leading me to an overall electrical issue due to how sporatic and spread out it is.
We used a HP Tuner to delete the MDS originally after seeing some of the MDS solenoids occasionally not actuating as expected. With a scanner, the solenoids all stroked as expected, but occasionally one wouldn't, causing the engine to shake like hell. A quick pull off the road and restart, and all would be well. We pulled and swapped the solenoids, rotated them, etc. There was no repeatable pattern we could see. Disabling it outright prevented the issue, so we decided to leave without the system engaged.
We also noticed the occasional code regarding the rear left speed sensor having issues. Through a combination of playing with it, the error seemingly went away since.
After installing an aftermarket remote start, there were times where the module wouldn't lock / unlock / start successfully. Many times, simply getting into the cab and turning to MAR / ON. The vehicle would immediately auto-crank if it was previously requested. I noticed on the scans that there was sometimes a B3004, and this would line up with a door sensor fault causing the auto-start and lock / unlock to act up.
I've recently been seeing a C1036 and C1436 occasionally pop up, but it never seemed to activate the CELs or jingle when rolling. Yesterday, while driving on the highway, I hit a pothole (just enough to cause a shake luckily) and my dash lit up like a tree. From what I recall, I had ABS, Stability Control and SERV 4WD active. Pulled off the highway and scanned with AlfaOBD. The ABS seemed to be the driver reporting an invalid wheel speed on my rear right wheel. I checked the remaining systems, and inspected the wiring harness and connector to the rear sensor. After inspecting, I got back on the road and the lights all cleared within 1km (I wasn't even back on the highway yet).
For the remainder of the drive, there was no major issues. It seemed whenever I hit a rough patch of road, the rear right signal was interrupted briefly, causing my cruise control to deactivate. There were no jingles, but I recall seeing the ABS light flicker once or twice when this happened.
I'm likely going to replace the speed sensors for good measure. Seeing the above issues, does it sound like a power issue? Are there any particular grounds that commonly fail? I'm hoping it's not the TIPM, but I know they tend to have issues.
