NOTESConditions for applying fault finding procedures to stored faults:
The fault is present with the engine idling.
Special notes:
When fault DF029 occurs, the idle speed is locked at 1000 rpm, there is engine noise,
the engine speed is unstable, the engine performance is reduced to 75%, the level 1
warning light illuminates, and the message Check injector is displayed until the next
time the ignition is switched off.

NOTESNone.
Switch off the ignition and wait 15 seconds.
Check the connection and condition of the cylinder 4 injector connector, component code 196.
Check the connection and condition of connector B (48-track) of the injection computer, component code 120.
If the connector(s) is faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Run command AC008 Cylinder 4 injector.
If injector 4 cannot be heard operating five times in a cycle, connect the wire of the cylinder 3 injector to
the cylinder 4 injector and use command AC007 Cylinder 3 injector.
Does this injector actuation cycle work?
Note:
If the wires cannot be swapped, continue the procedure by replying YES to the previous question.
