High Miler

[mr.mindless]

after this round, the important keys grew airtags that I intend never to take off. I HATE the extra bulk of a keychain thing on already thick modern car keys especially, but I'm *done* misplacing critical 1 of 1 items. overdue.

[mr.mindless]

NOT FIXED

FUCK

[mr.mindless]

Wish I’d been logging. Seems like ECU may have no power right now.

Edge CTS not connecting. No crank. Do have dash. 12.2v at cig lighter

[mr.mindless]

No crank after battery disconnect

Gonna leave them unhooked a minute

[mr.mindless]

No crank. Dead in the water

Guess it’ll be easier to diagnose?

[mr.mindless]

Spencer towed me home. Thanks!

[mr.mindless]

symptoms potentially match a TIPM issue. that's about a $1000 parts cannon shot. going to run through all diagnostics that I can find and go from there.

womp womp.

I did get Ecu connection right away and good vehicle ID

TIPM reports some weird values from PCM/ECU

65,635 rpm
Current speed 318.15mph

All else nominal and accurate to switched position changes and commanded tests.

Ecu functions mostly or entirely give communication errors

[mr.mindless]

[mr.mindless]

Cleared all codes. U1601 remained. ABS codes all remained.

TIPM
U0100 - no communication with ECM/PCM - active

TPMS and SKREEM (wireless) both still have U0141 not TIPM comm - stored



Seems possible to be ECM/PCM (which?) or a wiring harness issue somewhere.
I will check all fuses next step, could be no power to ECM?

Still no crank.

Will disconnect batteries overnight and come back to this

[mr.mindless]

common cause on the internets of u1601 is interrupted tuner coding. might be worth seeing if the Smarty Jr. will talk to it and try to reflash. I haven't touched the tune in ages.

[mr.mindless]

Contacted the ECU rebuilders at SIA electronics who fixed the N14 Cummins ECU for me on Joe.

Fuse and relay checking next, then I need to find a better continuity and resistance check table than I've found to go through the harness between the ECU/PCM/TIPM to check can bus things and supply pins. that'll be a thrill. Might try to get it in the shop, I don't think I've tried to move this one from its tail with the forklift before with the lunette ring.

TIPM is a one year part, '07 2500/3500

ECU is kinda crazy (and I'm making a maybe dumb assumption that pickup and C&C use the same)
