AUTOTRONIC 5 - PowerShuttle - Tests and diagnostics
Top-of-Clutch (TOC) sensor (56)
- on = violet
-off = white
Clutch pedal travel potentiometer value in
volts (+/-0.01V)
The high and low values are determined by
automatic calibration GUF514
Progress bar displaying clutch
pedal travel. Bar empty = clutch
disengaged and blue bar = clutch engaged
Forward proportional solenoid
valve current value
- lever in neutral position ....................................0 mA
- lever in forward position..................200 to 1000 mA
- lever in reverse position ........ 0 to 120 mA (“offset”
correction current due to Autotronic 5 internal
components)
Reverse proportional solenoid
valve current value
- lever in neutral position ....................................0 mA
- lever in reverse position ..................200 to 1000 mA
- lever in forward position........ 0 to 120 mA (“offset”
correction current due to Autotronic 5 internal
components)
Number of adjustments to forward clutch
progressivity
- (0) = no adjustment since Power Shuttle calibration
- (+#) = clutch responsiveness increased
- (-#) = clutch responsiveness decreased
Number of adjustments to reverse clutch
progressivity
- (0) = no adjustment since Power Shuttle calibration
- (+#) = clutch responsiveness increased
- (-#) = clutch responsiveness decreased
