When fitting a new RFA with a module part number of:
FK72-19H440 - AE
FK72-19H440 - BE
FK72-19H440 - AF
FK72-19H440 - BF
SDD cannot communicate with the RFA. This will be displayed as a red ‘X’ for the RFA
in the SDD vehicle specification screen.
Note:
This concern does not apply to modules with a manufacturing date after 23rd August
2016, which can be identified by looking at the date stamp printed on the module.
Cause:
The new RFA module supplied is manufactured with pre-flashed software for ‘DUAL
CAN’ vehicles. These vehicles are ‘MULTICAN’ and not ‘DUAL CAN’ and will not
communicate with SDD for programming or update without completing the action
instructions detailed below.
