GENERAL INFORMATION

Numbers of contacts of a connecting block of the control unit


PERFORMANCE ORDER
1. To disconnect a block of black color.
2. To measure by an ohmmeter resistance between contacts "1" and "2". It has to be about 1 kOhm. If resistance differs from specified, it is necessary to replace the ignition advancing corner sensor.
3. Then to measure resistance between contacts "1" and "3", "2" and "3". The ohmmeter has to show zero in both cases. If the ohmmeter shows any resistance, to replace the ignition advancing corner sensor.
4. To remove an upholstery under the dashboard on the right under which the control unit is installed.
5. To disconnect a connecting block from the block and to check conducting between a block of the sensor of an advancing of ignition and a block of the control unit.
6. For this purpose it is necessary to measure resistance between contacts "1" and "13", then between contacts "2" and "12" and, at last, between "3" and "28" (see rice. Numbers of contacts of a connecting block of the control unit).
7. In all cases the ohmmeter has to show zero. If the ohmmeter shows any resistance, means there is a break in conducting.
