Code 2385 help
CM870 code 2385 has 81 counts. VGT actuator driver circuit- Voltage above normal, or shorted to high source. Within the last 1 1/2 years it’s got a new engine harness, oem reman VGT, and VGT control box, with new air line going to the box, box to turbo also. What am I missing?. Also when cold the actuator “cycles” let’s call it. The actuator will slowly extend and contract, only when it’s cold though. Once it’s warmed up it’s good.

RE: Code 2385 help
Is it de-mandated?.

Does the engine file in the ecm match exactly, the engine ser#?.

does it have a factory file in it? .. or a delete file?

If so then who made the de(l)ete file?.

2385 means its loosing its ground connection.

bent pin in the ecm plug?.

ecm going bad?.

grounds on engine block getting corroded?.

excessive electrical noise?.

does it have this issue with the factory programming?.


- can be a lot of things.

I’ll start checking all the above, not sure if the code was there before the de mandate as the CEL was always on because of the EGR blocker, and got insite installed to my laptop upon tuning so I am only now able to check my codes.

RE: Code 2385 help
Im having the same issue. Once it is cold outside usually 31-35 degrees it will flash a check engine light. Ocasically around 1500rpm you can hear the vgt cut in and out. On startup at 31-35 it will flash it I mean lol

Also rawze, the vgt on/off stuff while cold has been happening prior to the tune.

RE: Code 2385 help
If it cannot be found, then run this test screen on it in CT along with some desktop recording software. At least see what the ecm is trying to command from the engine and its turbo, etc. while its acting up. See if everything in the ecm is operating it normally and/or if it simply sees an error.
