Where is the PCM and the ICM on a 2008 Buick Lucerne V6.
What is your question?
Car stops running.Sometimes at idle, sometimes at 70 mph. No hesitation. Just stops running.
In 5 or 10 minutes, if you are still alive. It will restart.
Codes are P0606, P0601 and U0107
Then 5 to 10 minutes later it will shut off again. At idle or at 70. ( no crank condition when it shuts off, but lights, windows etc still work fine)
Extremely dangerous, should be a recall or at least a TSB.
Thanks

Hi! this is Bo with Car Genius at RepairPal!
That is a real safety issue! Glad you're here to writhe this question!
The PCM is most likely near the air cleaner housing. The ICM looks like it sits right above the belt pulleys to the right of the engine.
In my research, I saw a lot of ICM/PCM replacements for a similar issue but know that it could be a fault in the wiring harness as well.
