1. If this cap is not transferred, fault code P309D may set in the transmission control module (TCM).
2. If the K0 aluminum cap was transferred over and P309D sets, or if there are issues with the Guided
Functions K0 clutch bleed, perform the following steps:
a) All faults have been cleared through Vehicle OBD
b) High Voltage connectors must have an audible click when secured
c) Parking brake is in the “OFF” position
d) All 4 passenger doors and hood remain closed during the basic settings
e) Trunk is “Open” with a battery maintainer installed on the 12v battery
After the above steps have been completed, perform K0 bleed test plan:
Step One:
Using ODIS, go to AW01 ECM  Guided Functions  Bleed Disengaging Clutch  then select option (1)
Ventilation and follow the Guided Functions steps in the test plan.
Step one should take up to 30 minutes to complete. Once the test is completed, the test plan will usually
exit out to the main control module OBD screen of ODIS.
Step Two:
Using ODIS, go to AW01 ECM  Guided Functions  Bleed Disengaging Clutch  then select option
(2) Air Entrapment and follow the Guided Functions steps in the test plan.
If DTC P309D returns, top off the Mechatronic with 30ml and perform the K0 bleed test again. The K0 bleed
test may need to be repeated several times to remove all air trapped in the system.
