1. Disconnect a wire from the - plug of the rechargeable battery. |
2. Remove the top casing of the engine (see subsection 2.1). |
|
3. Disconnect a block of the II plait of nozzles from a block of the I plait of wires. |
4. Connect an ohmmeter to the following contacts of a block 2: the first cylinder – contacts 7 and 5; the second cylinder – 7 and 3; the third cylinder – contacts 7 and 2; the fourth cylinder – contacts 7 and 6. In all cases resistance has to be about 0,5 Ohms. |
5. If resistance some pump nozzle differs from specified, measure resistance directly on contacts the pump nozzle. |
6. For this purpose remove the top cover of a belt of the drive of the camshaft, a cover of a head of the block of cylinders, disconnect from the pump nozzle a block with wires and measure resistance. |
7. If it differs from specified again, replace the pump nozzle. If resistance is normal, replace nozzle wires. |
