Inputs and Outputs
Inputs and outputs are directed to and from the ECM through hard-wired connections and the CAN and
ISO 9141/2 (Serial Communication) data buses contained in the engine management harness (for
further information on the data buses, refer to the Technical Guide, XK8 1997 Model Year Introduction).
