PEDAL ADJUSTING SENSOR
DescriptionINFOID:0000000001735519
• The pedal adjusting sensor is installed to the pedal assembly.
• The resistance of pedal adjusting sensor is changed ac cording to the forward/backward position of pedal
assembly.
• The terminal voltage of automatic drive positioner control unit will be changed according to a change of pedal adjusting sensor resistance. Automatic drive pos itioner control unit calculates the pedal assembly
position from the voltage.
Component Function CheckINFOID:0000000001735520
1. CHECK FUNCTION
1. Select “PEDAL SEN” in “Data monitor” mode with CONSULT-III.
2. Check the pedal sensor signal under the following condition.
Is the indication normal?
YES >> INSPECTION END
NO >> Perform diagnosis procedure. Refer to ADP-81, "
DiagnosisProcedure".
Diagnosis ProcedureINFOID:0000000001735521
1. CHECK PEDAL ADJUSTING SENSOR SIGNAL
