First of all,thanks guys for trying help! Car runs normally,but the ESP fault lamp on the dashboard indicates the problem. After deleting all DTC,and scan system again: ABS/TCS/ESP-ECB430EV: U2103:High speed CAN bus no communication intermittent U2142:Yaw rate sensor no communication intermittent EH...
I have U2103 C and U2105 DTC,Opel Vectra C 2003 Z16XE on all ECUs connected to high speed CAN bus.
Signals seems to be good,tried to change CIM module,the gateway between low and high peed bus,but still have DTC
