Ott_outback

Thank you for the input. I am going to chase some of the wires over the next bit. Disabling the 2 sensors sounds like a great idea I will see if its functionally possibility. Previous to routing the power and fused the power to the ECM we have have not retrieved any codes, the car would be just dead. On the positive side i feel that since we are able to crank the engine that the ECM is good. Any results I will post.

Hi everyone, I am new to the Subaru community.I bought a 2011 outback it has been great but...It has left us stranded on the side of the road 4 times in the past year. Fuse # 12 blows while driving...car dies and will not restart, replace fuse #12 turn the key, pop just keep blowing fuses, starter doesn't activate, no fuel pump noise. (fuse #12 is integrated unit and automatic transmission). symptoms seem to point to a dead short but my local mechanics are unable to find anything.... The FSM shows fuse #12, 15 Amps, in the cabin fuse panel powers: my OB is not TurboA/C Control ModuleBody integrated unitLight control sensorTransmission Control ModuleEngine Control ModuleFuel pump relayIgnition coil No. 1 (turbo model) Ignition coil No. 2 (turbo model)Ignition coil No. 3 (turbo model)Ignition coil No. 4 (turbo model) To date the mechanic has replaced the fuel pump relay (the day I went to pick it up it blew fuse 12 several times....even when it was bumped up to a 30A) To potentially isolate the problem from the other sensors that fuse 12 services they isolated the ecm. They ran a dedicated fuse (15amp) to the ecm. The thought was is if that fuse blows we know it's the ecm $$. If fuse 12 blows then it's either a dead short on that circuit or 1 of the 2 sensors (light sensor and there is one on the transmission I think). It happened again but because we have the ecm on its own fused circuit the car cranked but would not catch. Good juice to battery did not think to listen for fuel pump. Floated it to mechanic and they discovered that fuse 12 was blown yet again! Put in a new fuse and it runs. Code that were present when car got to mechanic yesterday wereU0101 lost comm TCMABS C0044 CURRENT TCMC0057 ECM ELECTRICAL PARK BRAKEC0231 ECM FAILUREC262 TCM COMMC0221 PARK SWITCH LINE ABNORMAL Sorry this has been a long post but i wanted to post as much info as i could. I will be chasing down shorts from fuse 12 over the next few weeks, hope to find the issue. Testing the light load and the transmission sensor are on the work order as well as inspect the wire and fuel pump relay harness. any other ideas/ experiences that people may have that could assist me in narrowing my workload would be greatly appreciated.
