Issue:
There is a requirement mismatch in the Continental IPMB that will result one of two
use cases:
1.
No trailer trajectories when using Tow Assist and car is in EV mode
2.
Failure to enter Advanced Tow Assist when car is in in EV mode
Cause:
Software and requirements do not match.
Action:
No action to take yet as there is no fix available.
Diagnostic Procedure:
Confirm the trailer trajectories are present in non EV mode and then disappear in
EV mode before returning to non EV to confirm the IPMB does render them
correctly. Repeat the same for Advanced Tow Assist feature entry.
