| Examine the cable for any broken wires at the car end. With the ignition on, measure the voltage on pin 10 of the car's diagnostic connector (connects to the V2 cable's pin that has a white wire) with no cable attached. It should be about 4.5V (3.5V for a 1990 ECU). Measure the voltage on pin 1 of the car's diagnostic connector (connects to the V2 cable's pin with the green wire). It should be pulsing, indicating diagnostic info. Check that pin 12 of the car's diagnostic connector (connects to the V2 cable's pin with the black wire) has continuity to ground. | Examine the cable for any broken wires at the car end.
