Dodge Journey: Module, glow plug

DESCRIPTION

Ignition Control
Fig. 23: Locating Diesel Glow Plug Control Module

The glow plug control module is mounted to the fuel filter/water separator bracket, and is controlled by the engine control module.

OPERATION

When the ignition (key) switch is placed in the ON position, a signal is sent to the ECM relating current engine coolant temperature. This signal is sent from the engine coolant temperature sensor.

The glow plug control module receives information about the glow function from the engine control module.

The start of glow plug operation, the period of glow plug operation, the actuation frequency and the pulse duty factor are therefore determined by the engine control module.
