Look in the trunk fuse box ,, it's a black 1''x1'' square fuse with a diagnal handle on it .. You cant miss it , its the biggest fuse in the fuse box..

The terminal 30 g relay prevents increased closed-circuit current consumption, and contains the defined deactivation of loads/consumers by the CAS

Hopefully when you pull it , it will stop the current draw ... Good luck !

I pulled that but didn't affect the fuel pump priming. As I said, I didn't think this model had a fuel pump relay. I finally made it to the glove box fuses, and finally, I was able to determine at the airbags is what is causing this. I pulled the airbag fuse, amperage dropped, and the car stopped priming the fuel pump. Now, onto determine what airbag is causing this...

That's really strange .. Let's us know what you find out ..

airbags and a lot of the core car electronics sit on a different CAN network therefore won't wake up the car. I assume the fuel pump sits on the same network

I would think so, as the fuel pump is stopped in case of an airbag deployment.

I learned something as well, as they fuel pump and airbags must to tied together. I left the airbag fuse out, and tried to start the car. First, the car struggled to start as if it wasn't getting any fuel,and of course every airbag warning available triggered. Lesson learned, need to put the fuse back before I start the car. I am still not sure really where to start looking. I pulled the seat sensors and that didn't resolve the issue. I believe I need to go to the module and start pulling from there, any other suggestions?

I dug up a schematic that backs your physical findings .. The SGM ( safety gateway module )has a direct PT-Can Bus connection to the EKP (electronic fuel pump ) module . I tried to upload a whole pdf file but was too large to upload . So here is the Bus overview diagram pic and index below. So its possible its one of the two modules that's causing the drain , SGM or EKP ...
But just thought ,, if you pulled the fuel pump fuse and still had a draw , the air bags don't controll the signal to the EKP, the SGM does . So the SGM could be the culprit and not necessarily the actual airbags ..

The fuse slot is 29, which says it is Airbag and Diagnosis. I didn't see the Diagnosis initally. What I have noticed when this fuse is pulled is the car will not lock/unlock the front doors, and arm the alarm. Also, will not wake the car from sleep mode either

H F

That makes sense because the SGM controls both driver (TMFA) and passenger (TMBF) door modules ,, that control the locking on both front doors . The SZL Steering column switch cluster,, is why it don't start . The SBSL B-pillar satellite, left, SFZ Vehicle centre satellite ,SBSR B-pillar satellite right ,, which control the air bags .. They are all on the same fuse circuit ...

I find it hard to believe that all those items are pulling a draw at the same time . I'm thinking it could be the SGM that's faulty ,,causing the EKP to prime , because of the PT Can Bus connection .. Or the SZL column switch ..

I would disconnect the SZL and put the fuse back in and see if the draw continues . That will give you an answer to rule it out .. And try the same with the SGM . Isolation of those items will give you the culprit

H F

I'm not fully convinced its the SGM ,, untill the SZL is ruled out or visa versa .

You can disconnect one module at a time , put the fuse back in , then see which one pulls a draw .. Hopefully by the process of elimination and isolation the culprit will present itself . I would try pulling the SZL first , that will leave the SGM to pull the current if indeed is the problem .. And if it doesn't ,,then that means its good .And its the SZL . Then plug The SZL back in and see if thats whats pulling the current ..
