Update: I checked voltage at pin 1 and 2, am getting 2.5 volts and 1.9 volts respectively. (with key on of course) I seen in another posting you mentioned checking at the TCM pin 18, and I have 12 volts there.
I dont know if I should conclude the TCM is bad or I have a wiring issue from the TCM plug down to the tranny harness.
Is there a way to test wiring from TCM to tranny?
If i'm getting 2.5 volts could that mean there is a short ? I'm a caveman when it comes to wiring issues, i can do all the mechanical stuff but electrical issues takes talent and most importantly understanding of the circuits.
I did find this online somewhere:
Checking resistance of solenoid valves
* Re-connect 12-pin connector.
* Connect test box to control module wiring harness, connect test box for wiring test.
* Measure resistance of solenoid valves at test box between sockets:
Component Sockets Specified value
Solenoid valve 1 -N88- 55 + 67 55.0 to 65.0 ohms
Solenoid valve 2 -N89- 54 + 67 55.0 to 65.0 ohms
Solenoid valve 3 -N90- 9 + 67 55.0 to 65.0 ohms
Solenoid valve 4 -N91- 47 + 67 4.5 to 6.5 ohms
Solenoid valve 5 -N92- 56 + 67 55.0 to 65.0 ohms
Solenoid valve 6 -N93- 22 + 58 4.5 to 6.5 ohms
Solenoid valve 7 -N94- 10 + 67 55.0 to 65.0 ohms
Note: Resistance value is valid at approx. 20°C. At higher temperatures, resistance value increases.
If one of the specified values is not obtained:
* Check wires to Transmission Control Module (TCM) according to wiring diagram.
Checking wires to Transmission Control Module (TCM)
* Disconnect 12-pin harness connector at transmission.
* Check wires between test box and 12-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
* Wire resistance: max. 1.5 ohms
Component Connector Test box
Solenoid valve 1 -N88- Terminal 1 Socket 67
Terminal 3 Socket 55
Solenoid valve 2 -N89- Terminal 1 Socket 67
Terminal 4 Socket 54
Solenoid valve 3 -N90- Terminal 1 Socket 67
Terminal 5 Socket 9
Solenoid valve 4 -N91- Terminal 1 Socket 67
Terminal 6 Socket 47
Solenoid valve 5 -N92- Terminal 1 Socket 67
Terminal 7 Socket 56
Solenoid valve 6 -N93- Terminal 2 Socket 22
Terminal 8 Socket 58
Solenoid valve 7 -N94- Terminal 1 Socket 67
Terminal 10 Socket 10
* Check wires for short circuit to each other.
* Specified value: infinite ohms
If no malfunctions are found in wires:
* Replace circuit board or valve body:
I dont have a V.A.G 1594 connector test kit which was mentioned by the author, but from what i understand I can check the wiring from the tcm socket down to the 12pin connector.
For example Valve 1 I check ohms on terminal 1(12 pin connector) + socket 67(at tcm) then another test for Terminal 3 + socket 55.
Thanks in advance for any input
