Fault code FMI 3 Conditions for fault code: • Short-circuit to voltage, low voltage side. • Feed short-circuited. Possible cause: • Short-circuit in wiring. Reaction from the engine electronic control unit: • Fault code is set. • MIL lamp requested. • Yellow lamp requested. • The particular injector or the whole of the affected injector bank is switched off. Noticeable external symptoms: • Power reduction. • Uneven operation. • 3 or 5 cylinder operation.
Appropriate check: • Active FMI 28472–3 “MID 128 SID 1/2/3/4/5/6 Injectors” page 5 . • Inactive FMI VCADS Pro-test: “17004–3 Fault codes, test mode”. If the fault code becomes active during test “Fault codes, test mode”, fault trace according to “Active FMI” If the fault code does not become active, try activating it during a test drive. In order to fault trace, the fault code must be active.

28325-3 MID 128 SID 1/2/3/4/5/6 Injectors Special tools: 9990014, 9998567, 9998699 Other special equipment: 9812519 Fault code information, see “MID 128 SID 1/2/ 3/4/5/6 Injectors” page 2.
NOTE! Note that small resistances are difficult to measure. It can be a good idea to use the value as a guide value when fault tracing in the injector circuits.
•
Active/inactive fault code Certain fault codes become inactive when the engine is switched off. Start the engine to check whether the fault code is still inactive or becomes active when the engine is running. • Connector block Always check that there is no oxidation or damage to the connector pins. Also check the gripping force of the pins. For more information, see service information Group 371. If the connector block is fault-free, reconnect it. Check if the fault code is still active. If the fault code is active, continue fault tracing in accordance with the instructions. • After repairing the connector as necessary Refit the connector. Check if the fault code has become inactive. If the fault code is still active, continue fault tracing in accordance with the instructions.
Measurements Note: If any of the following wiring measurements is incorrect, this can also have led to a component failure. Also check whether any of the component values are incorrect.
