DMTL
Tank - Leak Diagnosis (DMTL)
All DMTL pumps starting September 09, 2001 are heated in the tank-leak diagnosis module. A heating element is used in the DM-TL pump.
The heating element is activated during the driving cycle in order to prevent moisture in the pump. Moisture previously caused the tank-leak diagnosis to be terminated. The pump current could not be measured accurately under these conditions.
The heating pill is activated by the DME. The DM-TL connector has been changed from 3 pin to 4 pin electrical connector.
