Conditions for Setting the DTC

C0407 02 

The differential clutch pump current is greater than 9A in 20 consecutive test cycles. The current will be retested every 30s.

C0407 04 

The differential clutch pump current is less than 0.3A for 30s.

C0407 0B 

The differential clutch pump current is greater than 7A for greater than 2s in 10 consecutive test cycles.

C0407 64 

The differential clutch pump current is below a threshold at the end of a pump activation cycle in 30 consecutive test cycles. The measured current is less than 1.5A from the threshold. The threshold is temperature dependent.
