Performing Quick Tests - Weight Sensing System (WSS) Communication Issues
When performing a Quick Test on all MY2012 204 variant vehicles with 07/2011 and 09/2011 SDS software, the Weight Sensing System may either not show up in the control unit list, or you may receive the message:
"Timeout from the end of data sent from tester to the beginning of the response data from ECU" along with an exclamation point (!) next to the WSS module in the control unit list.
These are communication issues with the Weight Sensing System that will be fixed in version 11/2011, and with an add-on for 07/2011 and 09/2011 that will be released on Thursday, October 13, 2011.
Please continue to perform Quick Tests on these vehicles as normal. If you experience any Weight Sensing System errors (e.g. SRS light on, DTC stored/current in SRS control unit, or passenger seat recognition does not work); please perform a hard reset, ensure the supply voltage is sufficient, and re-calibrate the WSS. If this does not work, please contact DTS.
