seems like everything checked out.
I raised the front of the car so I could spin the wheels. pulled the ABS module connector and blew out with canned air but looked clean already inside. car was still slightly warm from my drive home 2 hours earlier.
found the 12vdc supply at pins 15, 17, 18 to 19GND.
checked impedence on all 4 wheels: front were spot on at 1600ohms. rears were little lower than spec (1130 spec) at just under 1100ohms. check.
checked vAC at both signal and reference pin of each front: pin 3 to 19GND, 5 to 19GND, 6 to 19GND, 7 to 19GND. all gave me 120-200 or more mVAC when spinning the wheels 1 rot/sec or faster.
I even plugged it back in, started the car to verify ABS still offline. it was. then I pulled the connector and checked the fronts again. all still had good readings.
I got lazy and did not spin the rears. also, looks like the T7 connector is under the windshield cover? I wasn't up for pulling the dang wiper arms to get into there to check pin 64 from ABS 25. not yet.
put it all back together and ABS was back online. means nothing but was curious as usually it has not been coming back online until car is cooled completely down. maybe it cooled enough. we'll find out tomorrow but I suspect it will go offline again after 5-10min of driving.
