UPDATED EAS DIAGNOSTIC CARD - VERSION 2.1
The Version 2.1 card improves the diagnostic capability of the HHT. The key differences as compared with the original card are:
^
Dynamic Tests - Now include additional information: Compressor thermal circuit breaker status, ECU demand height display, MPH and KPH road
speed display. In addition, the information is now in a more logical order.
^
Calibration - Improved calibration accuracy due to a software change which measures 3 rather than 2 values per wheel.
^
Initial tests - The valve test section is now optional and may be bypassed when, for example, the system has no air supply available.
^
When a "hard fault" relating to height sensors has been recorded, the initial tests don't have to be performed prior to clearing the fault.
