Good question. Here is the answer.

If you look at the E9x PDC file under coding index, you will see nothing related to RVC on that file. Why it is important?

PDC is the brain of the Reverse Camera Application. TRSVC is just an outsource to provide broadcasting to the CIC. PDC is the one actually sends the signal to TRVC and says Hey, Shift engaged to Reverse Start Broadcasting buddy, And he is all ready to turn the camera on and allow you to watch the back. Then you engage the shift to gear 1 or D then PDC says okay stop broadcasting and cuts the function and turns the CID screen back to wherever you left.

Without E84 PDC, There is no order like turn the camera on or off to the TRSVC and your TRSVC will never activate the camera.

Before the upgrade, i try to do custom Flashing and used E84 PDC file to implant on E9x PDC with failure. So e84 PDC is MUST.

Hope it helps!
