Control Module
The control module is located on the right to the rear of the engine bay. It is connected to the system's constituent components by a 10-pin connector.
The control module is supplied with current from the +54 circuit via pin 6 (F) and grounded via pin 5 (E).
Control module communication with the ABS control module: a speed signal is received from the LH front wheel on pin 10 (K) and Trionic is advised via pin 9 (J) when the cruise control is activated.
An electric stepping motor in the control module operates the cruise control cable mechanically. It pulls or releases the cruise control cable connected to the throttle body, depending on the difference between requested and actual speed.
Control Module Power Supply
+54
Current from the +54 circuit is supplied to the control module, terminal 6 (F), when the ignition switch is in the ON position.
If the control module is not supplied with current it will be inoperative.
