NOTE:

There are two versions of the B1400-1A DTC test. In order to select the proper test you must know if the vehicle is equipped with an Amplifier. If the vehicle is equipped with an Amplifier use the B1400-1A PREMIUM test. If the vehicle is not equipped with an Amplifier use the B1400-1A BASE test.

The Left Front Door Speaker (+) circuit and the Left Front Door Speaker (-) circuit are outputs of the Radio. The Radio controls and monitors these circuits for a concern.
