CYL2 INJECTOR OFFSET LEARNING

(Cylinder 2 Fuel Injector "A" Offset Learning At Max Limit) 		Diagnosis condition

  • Engine running

  • During injector offset learning
Signal —
Threshold

  • Injector valve opening delay time grater than threshold

  • Injector valve closing delay time less than threshold.

  • Injector offset correction value grater than threshold.
Diagnosis delay time —

POSSIBLE CAUSE

  • ECM

  • Fuel injector (Cylinder 2)

  • Harness or connectors (Fuel injector circuit is open or shorted.)

FAIL-SAFE

Engine Control System

Fail safe mode Nissan Ariya Vehicle behavior
Traveling control mode Accelerator angle variation control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This causes a drop in accelerating performance and encourages the driver to repair malfunction.

NOTE:

ECM does not control the accelerator pedal releasing speed.
Device fix mode

  • This mode fixes the electric IVT control actuator and the EVT control solenoid valve in the reference position.

  • A control signals is not transmitted to the EGR volume control valve and the EGR volume control is deactivated.
Combustion control mode Stratified charge combustion control at starting No stratified charge combustion at starting (cold start).

Stop/Start System

When a DTC is detected, the stop/start indicator lamp blinks slowly and the stop/start system operation is prohibited. When ECM detects error while operating the stop/start system, ECM restarts the engine.

DTC CONFIRMATION PROCEDURE
