All 8 codes here. Rough idle till warm then truck ran great. Reflowed the solder in the FICM last night, now the truck is fixed. Do the voltage check on the FICM to see if it is bad.

 

Ya....

I go that route because so often, electronics get the rap for the problem but the problem is everywhere else: connections, power, corrosion, etc.

So I always start there, eliminate (to the extent possible) that first, then go from there.

Too many electronic parts that are replaced get back to the OEM only to test perfectly good.

I am cognizant of many electronic parts that can test good, only malfunction in the field --- like the infamous tin whiskers problem, or the microscopic cracked solder joints, or the many failures out there.

But all too often, the real "fix" is the cleaning / jiggling of the wiring and connectors that come with replacing a part.

That is why I use that route first.,

 

Sounds like what mine was doing similar symptoms and threw same codes and turned out to be the FICM.

 

Here is something I found, a lot of helpful information.

Good way to start "the gearloose1 electrical elimination process".

 

In a future post, I will talk about the silliness of using a scan tool like AE to diagnose computer / wiring / sensor faults.

 

npccpartsman it will fall under the TSB 09-22-16, PC/ED subroutines, also the IDS when ya pull the codes for all 8 inj circuit low(each individually), will say to reflash, but usually after you do reflash the FICM fails and throws a FICM performance code P0611. Have replaced many of FICM for this, sometimes works but most times not just replace FICM.

 

I talked to one of my tech friends about it this morning. He quoted me the same TSB number and told me instantly FICM--LOL. Is that something new or has IDS always given instructions to reflash for any FICM related code?

 

Depends on the code
