INSPECTION AFTER INSTALLATION

  1. Check accelerator pedal moves smoothly within the whole operation range when it is fully depressed and released.
  2. Check accelerator pedal securely returns to the fully released position.
  3. For the electrical inspection of accelerator pedal position sensor, refer to " «COMPONENT INSPECTION»(/infiniti/m37/iv-2010-2014/remont/testing-diagnostics/#engine-control-system-vq37vhr) " (VQ37VHR), " «COMPONENT INSPECTION (ACCELERATOR PEDAL POSITION SENSOR)»(/infiniti/m37/iv-2010-2014/remont/testing-diagnostics/#engine-control-system-vk56vd) " (VK56VD), . CAUTION: When harness connector of accelerator pedal position sensor is disconnected, perform "Accelerator Pedal Released Position Learning". Refer to " «DESCRIPTION»(/infiniti/m37/iv-2010-2014/remont/testing-diagnostics/#engine-control-system-vq37vhr) " (VQ37VHR), " «DESCRIPTION»(/infiniti/m37/iv-2010-2014/remont/testing-diagnostics/#engine-control-system-vk56vd) " (VK56VD), .

Scheme 2: REMOVAL
Scheme 2: REMOVAL
  1. Remove instrument panel lower cover.
  2. Remove knee pad.
  3. Remove A/C air duct (left side).
  4. Remove mounting nuts of accelerator pedal assembly.
  5. Remove the cap and the inside mounting nut, and remove mounting nuts of accelerator pedal unit.
  6. Disconnect accelerator pedal position sensor harness connector and remove accelerator pedal assembly.
  7. Press the pins (1) with long-nose pliers and pull them out in the direction shown by the arrow (<==) in the figure below to separate accelerator pedal unit (2) and accelerator pad (3). CAUTION: Never disassemble accelerator pedal assembly. CAUTION: Never remove accelerator pedal position sensor from accelerator pedal assembly. Avoid impact from dropping, etc. during handling. Be careful to keep accelerator pedal assembly away from water.
