Troubleshooting:
With battery power (around 12V) and ground applied to the Steering Wheel Button box, and no button pressed the
voltage on the input wire(s) should be somewhere in the neighborhood of 5 volts. If they are not near 5 volts,
disconnect them from the OEM signal wire and check again. If they are not near 5 volts when disconnected, contact
Acutach Co. to return the defective unit. If they are near 5 volts when disconnected from the car, check the OEM
signal wire(s) to make sure the OEM radio/cruise units are not still connected to the circuit.
Double check your mode selection wiring to ensure you are using the correct mode for your vehicle.
To test the buttons on your steering wheel, disconnect the steering wheel signal wire(s) from the Steering Wheel
Button Box input(s). With the key off and an ohm meter across the signal wire and ground, you should see infinite
resistance with no button pressed.
When you press each button, you should see a resistance close to the resistance listed for that button on page 8.
To test your cruise button box, connect the power ground and connect the Steering Wheel Button Box input wire(s)
to the OEM Signal wire(s) as specified previously in this document. Disconnect all of the colored wire pairs. Turn
the key on. With an Ohm meter, test all of the colored wire pairs coming from the unit. With no button pressed, all
of the wire pairs should show infinite resistance. With the press of each button, the one wire pair should show a
near zero resistance. All of the other wires should show an open circuit.
Find your vehicle on pages 11-17 to find the mapping of buttons to wire colors for the tests.
If you do not get these results, make sure that the signal and power wire(s) in the steering column are cut, and the
Steering Wheel Button Box input wire(s) have good connections to the Steering Wheel Button Box wire(s) that go up
to the steering wheel, not down to the audio/cruise systems. If the signal wire(s) are not cut, the car's systems will
load the wire so the cruise button box will not work. Also make sure the Power wire is cut and the side that goes up
to the steering wheel is grounded to the same ground that the Accutach Co Steering Wheel Button Box uses.
If the input wire(s) are wired correctly, make sure that the voltage on the red wire is very close to battery voltage. If
it is not very close to battery voltage, make sure the connection to power is a good connection. Also, make sure
that you have a very good ground connection.
Feel free to contact Accutach company if you have any questions or issues with the Steering Wheel Button Box
