Fuel Injector






Injector Test
- Disconnect the injector wire connector from the injector.
- Place an ohmmeter on the injector terminals.
- Resistance reading should be approximately 1.2 Ohms.

General Information
The DRB II and Jeep/Eagle adapter can be used to determine certain fault codes in the injector circuit. To read fault codes "SYSTEM TESTS" must be selected from the main menu. The DRB II screens will provide instructions to prompt the technician through a series of functional tests. Any fault codes will be displayed on the DRB II screen.



Note: Always ensure fuel pressure is within specifications.
