possible to identify the defective injector(s).
Special notes:
When the fault occurs: there is engine noise, the engine speed is unstable, the engine
performance is reduced, and the level 2 warning light comes on with the message
Faulty injection displayed on the instrument panel.
See the Technical Note Wiring Diagrams for the vehicle.
Switch off the ignition, check the condition and connection of the injector connectors, component codes 193,
194, 195, and 196.
If the connector(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair) repair the connector(s), otherwise replace the wiring.
Switch off the ignition, disconnect the injectors (or the injector identified by faults DF026 Cylinder 1 injector
control circuit, DF027 Cylinder 2 injector control circuit, DF028 Cylinder 3 injector control circuit,
DF029 Cylinder 4 injector control circuit) and switch on the ignition again.
