Can you post a picture of your setup and a screen shot of the service tool?
Looking at the datasheet, pins C1-P3 is can hi, C1-P4 is CAN lo and C1-P5 is can shield. are these connected along with Power? (C2-P11 and C2-P12, C1-p1 are power supply + and C1-P2 is ground)
Do you see the CG-150 gateway as online? If it's online, you can scan the system for ECUs by pressing F8 (or go under "system" > "Scan system")
