ok so i followed the steps. plug b136 for the ecm was different but i was able to find the correct wire #16 it was in the correct spot visualy but the plug itself was a little different and missing wires for #1 & #2 pins so i just assumed that was it and moved forward. step 1 i was unable to do because i dont have the special subaru computer tool. but for step2 i got 0.8 ohm. step 3 i got 0.8 ohm. step 4 my multi meter stays the (1 .) i beleive that indicates a short? i went from plug b55 to any nearby metal and no change even went from battery ground and nothing. am i doing something wrong? i noticed that in the check column for step for it asks if greater than 1Mohm instead of just 1ohm.
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

a 1 is an open, not a short.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
what would that indicate? would that matter if i tested that without plugging the ecu back in?
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

as for the last part that means 1 megaohm(1M OHM)

Ask Your Own Subaru Question
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

if you were testing for continuity that means that wire is open(broken)

do i need to change the setting on my multi meter before doing step 3? or am i just looking for a different reading?

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok good. so plug b11 is mentioned but i dont see a diagram for plug b11
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

its not a plug they are just transmission grounds

Ask Your Own Subaru Question
Customer reply replied 3 months ago
i think thats step 6. im looking at step 5 it shows b11 having #19 &20
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

those are transmission grounds

Ask Your Own Subaru Question
Customer reply replied 3 months ago
thanks. so where would that be located? is that the plug under the intercooler on top of the bell housing that goes to the trans?
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

not real sure on the exact location, the one diagram gives a general location

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok. but is it a plug conected to a ground block or is it a plug that goes into annother plug? from the sounds of it in the steps it makes it seem like b11 is a plug that goes to the trans harness, but the in the diagram you just sent me looks like it has nothing coming off the back of it
Subaru Mechanic: David Craig, Auto Mechanic replied 3 months ago

I don't know. I'm going to open this up to the others.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok thanks. in the mean time ill look for a 20 pin plug in that area.
Customer reply replied 3 months ago
well i located b11 it was the grey 20 pin plug that goes back to the trans. i did step 5 and got 0.7 ohm on all. i got the same reading on step 7. the car starts up fine. does that mean its the tcm?
Customer reply replied 3 months ago
sorry i meant step 6 not step 7

B11 is a female plug going to the male plug on the transmission harness. Does your transmission up or down shift hard?

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

There is a TCM software update for shift shock on your transmission. You need to have the dealer check and make sure you have the latest software update.

Is the transmission harness ground bolt tight?

Ask Your Own Subaru Question
Customer reply replied 3 months ago
is that the one up by the starter?
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

no that is the engine ground

Ask Your Own Subaru Question
Customer reply replied 3 months ago
where is the trans ground?
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

near the pitching stopper bracket. It should be a 10 mm bolt.

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

Its on the transmission harness after b11 connector.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok that one, ill go check it real quick. i was getting a buzzing from the throttle body and a rappid clicking from the trans pan whith key on engine off
Customer reply replied 3 months ago

Customer reply replied 3 months ago
i unpluged it and then pluged it back in and then it stopped and i could freely move the butter fly. and thats when i noteced the rappid clicking inside the trans pan
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

The power supply circuit of accelerator pedal position sensor is open or shorted.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok so how do i test for that?
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

You have to correctly follow the steps in the service manual to diagnose. If your wiring harness test good then replace the TCM.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
i did all the steps in the procedure sent to me by the last mechanic.
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

Check for bent pins or corrosion in the bulk head connector. Check pin fitment on the female end of the bulk head connector.

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

Check for signs of rodents on top of the engine. Mice like to chew wiring on top of the transmission too.

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

B22 is the bulkhead connector.

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

Yes. Check all of your transmission harness grounds on the entire transmission harness. Follow the wiring after those connectors on top of the trans.

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

step 6

Repair the open circuit of harness between transmission connector and transmission ground, poor contact of connector and insufficient tightening of ground bolt

Ask Your Own Subaru Question
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

You will have to drop the transmission pan to access the grounds.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
i did step 6 and got 0.6 by touchin multi meter to pin 19 and the trans housing and then 20 and the housing. wouldnt that mean they are good?
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

The bolt could be loose but the ground is still touching. Engine vibration could cause it to lose connection.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
ok ill drop the pan and check
Customer reply replied 3 months ago
is there a way to test the tcm? would be much easier and allot less mess to pull the tcm than the pan lol
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

Test by swapping a known good TCM into it.

Ask Your Own Subaru Question
Customer reply replied 3 months ago
dang that i dont have. ill pull the pan. if all is good under the pan then it has to be the tcm?
Subaru Mechanic: Dan, ASE Certified Technician replied 3 months ago

You can clean the magnet while you have the pan off. And put in some new fluid. You will need 4 quarts of ATF-HP. Use the red rtv on the transmission pan.
