The way to test the engine electric control unit is to use the multimeter with high impedance, so the control unit won't be broken due to the parallel connection with elements in test. When the test is done, the power supply should be cut off, the igniting switch should be shut down, and the voltage and the LEV should be tested with the according voltage gear of the multimeter. To avoid breaking or loosing the computer connector terminal, a test box(equipment V.A.G1598 and cable V.A.G1598-9) is used to detect it, the terminal numbers are corresponding to the computer connector terminals.
