YESInjector 4 is not defective; the fault is in the injector 4 control circuit.
Check the insulation and continuity of the following connections:
–3LC between components 196 and 120,
–3KZ between components 196 and 120.
If the connection or connections are faulty and there is a repair procedure
(see Technical Note 6015A, Electrical wiring repair, Wiring: Precautions
for repair), repair the wiring, otherwise replace the wiring.
If the fault is still present, contact the Techline.
NOInjector 4 is faulty, replace the cylinder 3 injector, component code 195 (see MR 364
