| Pump learn problems with FORScan | |
Hi folks, been lurking here for a while, I post more regularly on AULRO, hope you can assist with this query.
I saw the various threads/successes on this forum with the Puma Defenders and FORScan. So, I gave it a go, and basic monitoring worked well, both with Android and Windows devices, while using a bluetooth ELM327 connector. I decided to try the pump learn procedure, figuring a) worst case no harm and b) it might improve engine running (not that it was running badly).
All started OK, and the procedure went through the injector "Temporary learning" step no problems. It then ran the "Adaptive learning" step, and got about 45% of the way through the procedure in total, but stopped with errors - the sort of errors were initialisation error, engine temperature, short to VBATT, and loss of connection to the ELM adaptor. Note that these errors didn't occur on each run, but across the three times I tried the procedure.
In any event, it has left me with a fault/DTC code of P268B - which I think means that the pump learn procedure didn't finish properly and needs to be re-run. This is the only DTC I have - no others, and no yellow "check engine" light.
As I say, I was connecting via a bluetooth ELM327 device - my suspicion is that it might not be a reliable connection and drop-outs may be causing the error. My only other guess is that my SCV (which is the original one) is not working properly and so the relearn can't complete (this is a total guess - and note that the car is running/idling/starting perfectly, with no abnormal fuel consumption). And, even with this P268B fault code, the car appears to be running fine - it idles very steadily, and a short drive felt normal.
So, thoughts welcomed. My initial thoughts are that I will get a wired/USB ELM327 lead and try that. Bluetooth is probably OK for monitoring but my suspicion is that it's not a good option for a service procedure.
My final question: does anyone have a point of view as to whether I should/not drive the car before completing the pump relearn successfully?
My thanks to all in advance!
