The EATC module communicates with the scan tool through the UBP communication network. Circuit 1906 (VT) provides the network connection to
the EATC module. The EATC module shares the UBP network with the instrument cluster, the vehicle security module (VSM) (if equipped) and the
driver seat module (DSM) (if equipped). Voltage for the EATC module is provided by circuits 296 (WH/VT) and 729 (RD/WH). Circuit 875
