337 – AL Wiring Cylinder B7
ZKP-Number: 1.8004.536
Cause Corrective action
Cabling fault in injector cabling to
cylinder B7. Result: Misfiring 1. Rectify injector solenoid valve short circuit (positive to negative)
(e.g. by exchanging injectors).
2. Error cleared after restarting the engine.
338 – AL Wiring Cylinder B8
ZKP-Number: 1.8004.537
Cause Corrective action
Cabling fault in injector cabling to
cylinder B8. Result: Misfiring 1. Rectify injector solenoid valve short circuit (positive to negative)
(e.g. by exchanging injectors).
2. Error cleared after restarting the engine.
339 – AL Wiring Cylinder B9
ZKP-Number: 1.8004.538
Cause Corrective action
Cabling fault in injector cabling to
cylinder B9. Result: Misfiring 1. Rectify injector solenoid valve short circuit (positive to negative)
(e.g. by exchanging injectors).
2. Error cleared after restarting the engine.
340 – AL Wiring Cylinder B10
ZKP-Number: 1.8004.539
Cause Corrective action
Cabling fault in injector cabling to
cylinder B10. Result: Misfiring 1. Rectify injector solenoid valve short circuit (positive to negative)
(e.g. by exchanging injectors).
2. Error cleared after restarting the engine.
341 – AL Open Load Cylinder A1
ZKP-Number: 1.8004.540
Cause Corrective action
Disruption fault in injector cabling
to cylinder A1. Result: Misfiring 1. Check continuity of injector cabling or exclude open load in
solenoid valve circuit (e.g. by injector replacement)
2. Error clearance: After each working cycle.
342 – AL Open Load Cylinder A2
ZKP-Number: 1.8004.541
Cause Corrective action
Disruption fault in injector cabling
to cylinder A2. Result: Misfiring 1. Check continuity of injector cabling or exclude open load in
solenoid valve circuit (e.g. by injector replacement)
2. Error clearance: After each working cycle.
