|
Testing using a test instrument must not be carried out on the ignition circuit with components connected.The components must be disconnected and a reference resistance connected before testing is carried out. Values can be read from the ignition circuit with components connected when using the diagnostic tool. The values stated for the diagnostic tool show within which interval the resisitance should be with a correct circuit. |

|
All units on the I and P-buses send signals. |
