Schematic for the Position Sensor (Lift) of the Joystick
This diagnostic code is recorded when the implement electronic control module (ECM) determines that the signal for the position sensor (lift) of the joystick is too low. The position sensor (lift) of the joystick is a 500 Hz pulse width modulated sensor.The possible causes for this diagnostic code are listed:
The position sensor (lift) of the joystick rotated below the calibrated operating range.System Response:The machine response is listed:
If the diagnostic code is active for at least three seconds, then the 352-13 diagnostic code will become active. The 352-01 diagnostic code will become inactive.Note: The following test procedure may create other diagnostic codes. Ignore these created diagnostic codes and clear the diagnostic codes when the original diagnostic code is corrected. Note: Ensure that the diagnostic code is active.Test Step 1. CHECK THE ALIGNMENT OF THE POSITION SENSOR (LIFT) OF THE JOYSTICK
Check the mounting hardware for the position sensor (lift) of the joystick. The fasteners should be tight. If the sensor shows any signs of damage the hardware should be replaced.
Check the duty cycle of the position sensor (lift) of the joystick. In order to measure the duty cycle of the sensor, use a 9U-7330 Digital Multimeter with a 7X-1710 Multimeter Probe. At the implement ECM, use contact J2-30 and contact J1-15. Move the joystick to the full travel in both of the directions that are for the lift function. Expected Result:The duty cycle should be between 10% and 90%.Results:
YES - The duty cycle is correct.Repair: Calibrate the position sensor (lift) of the joystick.STOP
NO - The duty cycle is not correct.Repair: Replace the position sensor (lift) of the joystick. Calibrate the new sensor. Check for an active code.STOP
