Checking the injectors

1. The serviceability of the injectors is best checked using the Bosch 6E84.100.202 control device in positions 6-10 of the program switch. If not, then the serviceability of the injectors can be checked as follows:

2. Disconnect blocks from atomizers.

3. Turn on the ignition.

4. Check up a voltmeter tension on both contacts of a block. The wiring and the electronic control unit are OK if the voltmeter shows the same voltage on both contacts.

Attention! The injectors are rated for 3V.

5. Attach blocks to nozzles.

6. Plug the fuel supply line to the starting injector.

7. Remove nozzles.

8. Disconnect a wire from the distributor of ignition.

9. Turn on the starter. The injectors must inject fuel at regular intervals.
