bawareca,
So, if battery is under 11v or so(whatever the given value is), car will not click like what I experienced?
If I hook up the GT1, will it be able to tell me if EWS is good or not? Or is there a way to test EWS by using multimeter?
I'm using auto enginuity and it does recognize EWS module. I see no error in the EWS module when it happened(no click). The 94 DTC code for EWS was stored in enhanced powertrain module. However, I checked the original codes that I saved when the car first stalled. There was a 0F DTC code in EWS module. (it says something like "EWS reset". can't remember exact description. don't have it with me now.)
I already took off ground line on battery earlier today before heading off work. I was hoping it will reset it somehow. I'll hook it back on later today and see if I'm lucky. (hope so)
Thanks bawareca!
