BatterySaver ends triggering P317E 000B EV/HEV Battery System EVC-249

Open luipir opened this issue 4 years ago • 3 comments

Testing BatterySaver I repeatly have issue when the target SOC is reached. These are the steps:

  1. setup a Baterysaver percentage as in the manual
  2. plug charger
  3. start charger disabling charge programmer (e.g. chager right now)
  4. wait for reaching the target SOC
  5. charge ends correctly but: A) the three bluelight remain all turned on B) a DTC is trigered P317E 000B EV/HEV Battery System EVC-249

Side effect: detecting P317E prevent fast or slow charging => DTC clean procedure need to be performed

These is the triggered DTC and my installed firmware: photo_2021-10-17_14-00-36 photo_2021-10-17_17-50-27

@westsince2001 sorry, in my case I hadn't time to do more investigation, especially because I do not have a reliable and cheap way to dump canbus under linux (I spent the few time that I've to find a solution) I could use the same canbrdige to do log, but this give processor overhead that can not garantee that some messages are skipped. @westsince2001 btw seems I'm the only one having this issue... do you have the same too?

the main problem of the issue is that this prevent next charge => a DTC clean have to be performed... probably can be added at the end of the process. This could be a solution... need these steps that have to be added to the enhancer code:

  1. can log of leafspy to get DTC list
  2. identify if a DTC P317E 000B is triggered
  3. can log of leafspy to clean the upper DTC
