ODB II Freeze Frame Data Help
Hi,
Could anyone knows what kind of "fault" is ODB II freeze frame data is referring to? What would be possible causes? solutions? Freeze frame item and value: GM.ENGINE.12SOL 1-2 Solenoid --- Fault GM.ENGINE.EVAP_VSOL EVAP Vent Solenoid --- Fault GM.ENGINE.EVAP_PRG EVAP Purge Solenoid --- Fault Thank you!!! |
That data was from a test wasn't it?not live data?
|
the freeze frame data is the actual data stored at the time of the fault or failed test.
post the alpha-numeric diagnostic trouble code that has set. From what you have posted; looks like you have 1 transmission code and 2 Evap monitor codes. The format for the code will be a P0 or P1 follow by 3 digets ie. p0420 or p1760 |
No trouble codes have been set.
|
freeze frame data is only recorded when a code is set.
What are you using to retrieve this information; a laptop based scan tool? |

What were you trying to solve if the check engine light is not on?

then there is nothing wrong with you car. Your laptop/scan tool is giving you red herrings. Cheaper laptop based units don't convert the data like a scan tool will. It may be reporting a fail for a test that the task manager doesn't run
