Module voltage

[Cjchap]

Hello. Does anyone know where I can find the voltage ranges for the modules that are ran by fuse 11.  Fuse 11 consists of sentry key remote entry, cluster, radio, hands free, satillite receiver, monitor/DVD and electronoc overhead. I have looked everywhere. Thanks!

Everything should be 12v... Are you seeing something over 14.3 or so (approximate charging voltage)?

No. I'm chasing a gremlin on fuse 11. I'm seeing 8.6volts being back fed on feed wire to the ECM.

Since everything on CR truck is part of the TIPM (Totally Integrated Power Module) I would say the  TIPM is maybe causing the issue. Fuse box and the TIPM are the same.

That's what I was thinking. I was having back feed issues on fuse 6 too. I tracked that down to bad clutch fan and wastegate solenoid. That problem solved. I'm getting 8.6v back fed to fuse 42 (ECM) on the feed wire with fuse 11 plugged in. There is 2.5volts on positive and negative of  CAN BUS. When I went out there i heard a hum like the power seat is moving but its by the pedal under the dash. No key on. All fuses in except 42.

2.5 on can bus is correct.

When the CAN BUS is awakened it back feeds the ECM with 8.6volts. (The CAN neg and pos show solid 2.5volts. No fluctuation. This is all with key off.) When CAN BUS goes to sleep the 8.6volts that's back feeding ECM fades away slowly to zero.

Got ya.

I just ordered new Tipm, clutch fan ,and wastegate solenoid. Now I'm gonna pray to the dodge god that it fixes the issues.
