Condition 3
The TCM power up temperature changes by 20锟斤拷C (36锟斤拷F) or greater 5 times over 7 seconds.
P06AD
* The TCM power up temperature is -59锟斤拷C (-74锟斤拷F) or less for 13 seconds or greater.
* The TFT is 140锟斤拷C (284锟斤拷F) or greater for 60 seconds or more.
P06AE
The TCM power up temperature is 164锟斤拷C (327锟斤拷F) or greater for 10 seconds or more.
Action Taken When the DTC Sets
* DTCs P06AC, P06AD, and P06AE are Type C DTCs.
* The TCM allows the vehicle to operate in transmission protection mode.
Conditions for Clearing the DTC
DTCs P06AC, P06AD, and P06AE are Type C DTCs.
Diagnostic Aids
During a road test, the TCM Power-Up temperature should steadily increase to a normal operating temperature, and then stabilize.
