We had an overheating problem a month or two ago and an error code popped up stating the thermostat was bad. I went ahead and changed the thermostat and everything looked great until yesterday when we had the yellow, then red overheating messages appear. Stopped the car for 5 minutes, then brought it home with no more warning.
I hooked up my adapter running INPA, and pulled a number of codes. Only thing is I did not reset the codes after I changed the thermostat. Today I wrote down all the codes and reset them. So I'll keep an eye on it. I am thinking it may be the water pump since we are at 160K with the original pump. Wasn't sure if the water pump has a code it spits out if it is going bad. When I run the bleeder test, it spits out water in the expansion tank and I can hear it turning on and off for the 12min or so cycle.
Below is a list of codes. I could not find most of them on the internet. Does anyone have a way of finding some of these codes (the ones without any comments)? I'll keep looking and post if I find anything else.
Really hoping to get some insight from these codes to help diagnose this continued overheating issue. If nothing comes up, I'll just change the pump and hope for the best.
Thanks for the help.
********* Updated on some more info I found. Looks like the water pump is going out ************
SIM/SGM 942B 20 (I believe this is an issue with the passenger air bag system which we have had since the car was new. Dealer used to reset this and say it was fine. Rarely comes on)
SZL 94E7 60 (comes back on after reset. This is a known issue with the steering wheel positioning sensor)
94E4 20
94C6 20
STVL/TEFA 9645 20
STVR/TEBF 96C5 20
SFZ 9AC5 20 (satellite vehicle center) Not sure what this means
DME/DDE 2A15 A1 (tank-ventilation-system major leak. Recently changed the gas cap, old one was loose, but message came back on again after new cap installed)
2E81 01 electrical cooling pump:, speed deviation
2E82 04 electrical cooling pump: switch off
DSC 5EBA E0 (comes back on after reset. Also related to steering wheel positioning sensor)
RLS DA44 20 (Rain / Driving light sensor) No idea what this means
SINE 9D12 01 (Siren with tilt sensor) No idea what this means
KOMBI A557 28
FAS E447 24
SBSL 9845 20 (Left side satellite b-pillar) Possible error when window stuck once?
