Failed calibration
If the controller cannot measure the throttle correctly, or when there is no expected
throttle activity for 20 seconds during any of the calibration screens, the HHP will show
'Failed'.
Figure 38: Failed calibration
If this happens, press RETRY to repeat the calibration from the start, and go back to step 4.
6.1.2 Diagnostics menu
If a fault exists, the HHP can show extended diagnostics information.
Figure 39: Diagnostic information
1. In the Main Menu screen, press DIAG to enter the Diagnostics Menu.
2. If a fault exists, the System Faults screen gives a description of the current fault.
3. Press NEXT for the fault log. The fault log shows the last four faults that have
occurred. The faults are shown in 4-digit numbers. See 7.4 HHP Fault Codes with sub
codes for more information. Press MORE to see earlier faults; up to 16 faults can be
displayed.
4. Press NEXT to access the usage counters. Press MORE to see the counters one by
one.
Usage Counter Description
Time on (h)* The total time that the unit has been powered up
Power-ups* The total number of successful power-ups
Drive Time (h)* The total time during which the throttle has been deflected
Drive Count*
The total number of times that the throttle has been deflected and
returned to neutral
* The HHP reads the currently active value of these parameters. A diagnostics report made with the Wizard shows the
values that have been stored the last time that the unit was turned off. For this reason, the usage counters shown in
the Wizard are usually slightly lower than the values shown in the HHP.
