P0243 Code - No +12V to wastegate solenoid

So lets start with the code I know its not list here. The P0243 code is a wastegate solenoid issue. Either there is no +12V power or no control from the ECM on the ground side.

Now I can say that this wiring diagram is not very helpful at all. The wire colors are wrong here too. The plug at the solenoid is Dark Blue (ground to ECM) then there is pink/yellow. Then tracing back from the solenoid I do have continuity from the pink/yellow to the C130 connector. At this point the wire swaps to red/orange color heading to the TIPM. Now that red/orange wire now there is two connectors in the TIPM that have this red/orange colored wire going to the module. One is constant hot +12V the other one is dead even key on. A friend informed me it might be powered with tach signal (engine running). 

 

I've thought of cutting in a new key hot power line to the c130 connector and going form there. I don't want to start chopping up wiring to make this work. The other problem is there is no continuity from the c130 to either red/orange in the TIPM. Now I'm stumped. 

 

Little info or help would be nice...

 

ADDON: I finished my oil change and then fired up and checked the orange/yellow wire at the TIPM and there is no power present. Fuse is good. Power across the fuse as well. Even with the solenoid removed from the turbo and unplugged there is no code for the solenoid being missing. I figured it would pop the code fairly instantly. 

 

According to the 2006 Dodge FSM 

• When Monitored:
When the ignition is on.
• Set Condition:
The ECM detects an open or short circuit in the Wastegate solenoid circuit.

SOLVED!!!

Number 1 the Dodge FSM book has a error in the wiring map in the P0243 code document. But if you go to the 8W-30-28 page in the 2006 Dodge FSM and look at the wastegate solenoid versus the P0243 page with its map two different things. Here is the correct diagram.

Then here is the incorrect map that is provided at the P0243 code...

Now take look at the fuse number. The second one is fuse #36 vs the correct one that is fuse #6. Then look at the wire color on the second one the map calls for one grey/pink. Then the correct one is pink//yellow from the solenoid to the C130 connector. Then above the C130 connector turns to the Red/orange which the first map is correct. So this could really mess with you. 

 

So back to the problem the previous owner must have blown that fuse and never replaced it or something because the port was empty for #6. Now that I plugged a 30A fuse in it since that was my biggest fuse on hand the error code is gone. Then now that solves the other problem with the fan clutch and summer overheating being the same fuse that runs the fan clutch. 

 

Just needed a fuse in the #6 port and problem solved.
