Im not going deep into the weeds here, I realize you simply want your OBD to connect, but a little background info is useful for later when well be running some tests. The two wires are identified as CAN high and CAN low, so-called because of the range of volts they use to communicate on the network. Lots of communication codes within the vehicles ECU. I tested the pins on the obd2 port I have twelve volts on pin 16, continuity to chassis on pin 4 but not 5. Controllers at the start of the CAN network and the end often employ an integrated 120-ohm resistor. Labor: 1.0. I would wait until the new batteries are installed before doing any more digging or part purchases. When unplugging the TCM which is a pain to get to. And finally, if both wires are open in one of the branches of the network, only the modules that are on the open side of the network will be affected. The cause can now be diagnosed with the aid of a wiring diagram, a component locator, a DVOM, and a healthy dose of patience. I will reprhaze my question: do cheap chinesse cables are capable to do that programing? If you dont have the VIN handy, click the vehicle tab, and you can search by year, model, and manufacturer.
