System Operation

WARNING: This page is about a different variant/trim than selected.

Electrical power for the charge air coolant pump is supplied from the intercooler water pump relay in the power distribution box. When the intercooler water pump relay is energized, it connects power from the battery, via the BJB (battery junction box) and CJB (central junction box), to the charge air coolant pump. Operation of the intercooler water pump relay is controlled by the ECM (engine control module). The intercooler water pump relay is energized continuously while the ignition is in power mode 6.

When the charge air coolant pump is running, coolant flows from the pump outlet through the charge air coolers, the charge air radiator and back to the pump inlet.
