[11] ACCELERATOR SENSOR CALIBRATION (for B3350)
• When the engine ECU or throttle sensor is replaced, this
calibration is required.
(Tractor condition)
• Parking Brake: Engaged position (Parking brake switch ON)
• HST Pedal: Neutral position
• Range Gear Shift Lever: Neutral position
• Accelerator Lever: idling position
1. While pressing both the parked regeneration switch (1) and auto
regeneration switch or DPF INHIBIT switch (2), turn the key
switch to ON position.
2. Release the both switches.
3. Parked regeneration switch (1) and regeneration indicator
flashes (4).
4. Press and hold the parked regeneration switch longer than 1
second.
• If the voltage is not within 2.4 V to 3.0 V while the parked
regeneration switch is being pushed, accelerator sensor
calibration will not be performed.
5. Buzzer sounds for 0.5 seconds, regeneration indicator (4) turns
ON, parked regeneration indicator (5) flashes and parked
regeneration switch (1) flashes.
6. Set the accelerator lever (3) maximum position.
7. Press and hold the Parked regeneration switch longer than 1
second.
• If the voltage is not within 4.0 V to 4.6 V while the DPF
INHIBIT switch is being pushed, accelerator sensor
calibration will not be performed.
8. Buzzer sounds for 0.5 seconds, regeneration indicator (4) turns
ON, parked regeneration indicator (5) turns ON and parked
regeneration switch (1) turns OFF.
• If the ECU reading fails, the buzzer sound intermittently for
5 seconds, regeneration indicator (4) flashes, parked
regeneration indicator (5) flashes and master warning
indicator (6) flashes. In this case, try the calibration again.
If trying the calibration sometimes and still ECU reading
fails, replace the engine ECU.
9. Turn the key switch to OFF position to exit.
• If the parking brake is released while in accelerator sensor
calibration mode, processing exits the accelerator sensor
calibration mode and returns to normal key ON status.
