Low brake fluid level message
Low brake fluid message , fluid is full.
looking for voltage specs for fluid level sensor for diagnostic purpose
pin 1 brn/blu
pin 2 grn/blk
both wires go to vescm from there data bus communicates.
thank you
Your brown blue is your sensor ground, it shares a common splice location with your windshield washer level sensor, coolant level and outside air temp sensor. Your green black is the 5 volt signal from the J519. The area under the booster is prime rodent damage area on that vehicle.
Solved ,brown blue was broken inside insulation about 6 inches from connector. did not have 5 volts on green black , had 2 volts. Repaired the broken brown blue and no more low fluid message.
Have you tried tapping on the brake reservoir to free up the sensor level magnet? They do get stuck when the fluid gets too low. People add fluid and expect it to automatically read correct. It has to be tapped to rest the magnetic float
