ACM
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
Most of those faults are actually abs faults. For communication and front radar faults for the vec system. The one acm fault is a power fault. On your batteries there is a single red wire. Make sure that is tight. They come loose often and can cause this. When you have an after treatment fault the lamp will still stay on until it goes thru a drive cycle and see the fault not come up again. Please let me know if you have any follow up questions on this. Thank you

The check engine is on currently. Which code is for the engine?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
The 1072 is for engine compression brake 2017 is for cruise control status.The spn is a possible fault within the engine ecm as well the elogs do not do a good job at giving the source addresses sometimes for which module is broadcasting the fault since some modules crossover the spn numbers.

does the ACM fault and check engine refer to the after treatment?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
If the acm, yes. There is no acm fault codes on your listDo you have the basic software dash where you can’t read the fault codes from it?

The paper logs message is a Volvo link problem. There is a software update to address that

Is that done at Volvo dealer?
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
that is correct. There is a field service bulletin for it

Ok. So for the check engine light and ACM fault you recommend checking the red battery wire first? If that doesn’t work let dealer check for codes.
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
It is also not known the priority of the faults with the absence of time stamps and freeze frame data

When that KT system does the same time stamps that means it is incapable of reading the right time stamps. Qualcomm systems don’t the same like this

I shouldn’t rely on these codes, only the ones that show up on the dash.
Technician: Mike Mcmillan, Shop Foreman/Triage Tech replied 3 years ago
I’m just talking about the time stamps. A few of those faults there are software updates that will help with them
