This is a technical help for v1.45 opcom user at wobd2.
My opcom china clone (v1.45) has stopped working
it loads up, but when it tries to connect to the ECU it freezes and the TX light stays on constant no matter what i do.
Astra G with Z18XE engine.”
Suggestion by wobd2 technicians:
try these tests and see if they connect
Immobiliser>does it connect?
Instruments>does it connect?
If you have an original VX radio then do this test too
(pick you radio) does it connnect?
By performing these tests you have testing Pin 3, 7 and 12 on your car which is all the pins that your car used. If it will connect on pin 12 and 3 then we know that the problem lies with the pin 7 circuit on the interface or the car. Chances are its the interface relays. Most times they just need resoldering.
