Setup
Powering the Device
The KW470 is typically powered directly from the vehicle's OBDII port when connected, or via the battery clamp cable when performing battery tests. No external power source is usually required during operation.
Connecting to a Vehicle (OBDII)
- Locate the vehicle's 16-pin Data Link Connector (DLC), usually under the dashboard on the driver's side.
- Ensure the vehicle's ignition is off.
- Connect the KW470's OBDII cable to the vehicle's DLC.
- Turn the vehicle's ignition to the ON position (engine off). The device should power on automatically.
Connecting for Battery Test
- Ensure the vehicle's ignition is off and all accessories are turned off.
- Connect the red clamp of the battery tester cable to the positive (+) terminal of the battery.
- Connect the black clamp of the battery tester cable to the negative (-) terminal of the battery.
- The device should power on.
