The following abbreviations are used to represent values for Control Module Pin-Out data
I Input SG Sensor Ground S SCP Network V Voltage (DC)
O Output A ACP Network D Serial and Encoded Data Hz Frequency
SS Sensor Supply V C CAN (Network) B+ Battery Voltage kHz Frequency x 1000
CAUTION: The information on this data page is furnished to aid the user in understanding circuit operation. THIS INFORMATION SHOULD BE USED FOR
REFERENCE ONLY.
NOTE: The values listed are approximately those that can be expected at the control module connector pins with all circuit connections made and all components
connected and fitted. “Active” means a load is applied or a switch is ON; “Inactive” means a load is not applied or a switch is OFF.
Refer to the front of this book for detailed information and illustrations regarding the location and identification of harnesses, relays, grounds, control
modules and control module pins.
