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, fuses, grounds, control
modules and control module pins.
