| - | When all else fails, check the basics. Here's some information posted to our forums related to basic checks you can perform on the 1G diagnostic connector in the car. First, make sure the car's ignition is turned on when you're trying to connect DSMLink. 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 DSMLink 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 DSMLink 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 DSMLink cable's pin with the black wire) has continuity to ground. | + | When all else fails, check the basics.
