If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. SBW shifter control module internal ATP-P line check

   -1. Measure the voltage between test points 1 and 2.

   Test condition	Vehicle ON mode
   Test point 1	SBW shifter control module 20P connector No. 14
   Test point 2	Body ground

   Is there battery voltage?

   YES 

   Faulty SBW shifter control module. Replace the SBW shifter assembly .
