Numbers of contacts of the connecting block of the control unit
Order of execution
1. Disconnect the gray pads.
2. Measure the resistance between the contacts with an ohmmeter «1» And «2», it should be about 1 kOhm. If the resistance differs from the specified value, the sensor must be replaced.
3. Then measure the resistance between the contacts «1» And «3», then between contacts «2» And «3». In both cases, the ohmmeter should show zero. If there is any resistance, replace the frequency sensor.
4. Check the wiring between the frequency sensor block and the ignition control block. To do this, disconnect the connecting block from the block.
5. Measure the resistance between the contacts with an ohmmeter «1» And «29», then between «2» And «11» and finally between «3» And «28» (see fig. Numbers of contacts of the connecting block of the control unit.
6. In all cases, the resistance must be zero. If the ohmmeter shows any resistance, then there is a break in the wiring.
