Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Use the "Universal bornier" to check the insulation and continuity on the following connection:
Injection computer, connectorB, track A1 Track 2 of cylinder 1 injector
Repair if necessary.
Measure the resistance of cylinder 1 injector between tracks 1 and 2.
Replace the cylinder 1 injector if the resistance is not
14.5Ω ± 0.7Ω at 20°C (except F4RT 774 RS)
12Ω ±0.6Ω at 20°C (F4RT 774 RS only)
If the fault is still present, replace the cylinder 1 injector.
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
