This is my DVM
So, I tested my TCM again, according to the Shift Pointers document.
C9 is 0V with Key On, in D.
C14 reads 0.F -- I get this reading at the firewall connector too.
C15 reads 13.5 ohms -- I get this reading at the firewall connector too.
C16 reads 0.F -- I get this reading at the firewall connector too.
According to the user's manual, "0.F" is when the measured value exceeds range.
My DVM has a 'short' tester to test a short in a circuit.
From D7 to D3, D16, C10, C15 all read "short". All other pins are "open".
Now, my few questions:
1. What tells the TCM that the gear selector is in D?
2. Why did D7 to C15 short, when C15 read proper ohms?
3. How do I test the Speed Sensor?
