I bought a 2018 RAV4 which has radar cruise control.
I do NOT like radar cruise control.
If I hold the CC button in for a number of seconds, it will bypass radar CC and allow normal CC.
I have a few of the old 8 pin internal osc PIC IC's lying around and my old vellman programming kit.
The PIC CCT will sit in between the CC button and the CC ECU.
I want the PIC to output the signal to the CC ECU, for a couple of seconds, on just a brief press of the CC button, so the CC ECU thinks I am holding the CC button in, so that the CC ECU goes to normal CC mode.
The more trickier one I then want is that on another brief press of the CC button, the cct outputs a double short pulse, like a double press of the CC button. This then makes the CC ECU think I have turned off CC, and turned it on again, which will enable Motorway CC, if I ever want it.
The CC does not necesarily need to be turned off as it will turn off when I turn off the car ignition(by pressing the stop button in this car's case).
I haven't programmed a PIC chip in many years, so has anyone got PIC basic code that will do this, and what other components do you think I will need to properly isolate my cct from the CC ECU?
GAWD I hate modern cars where the car makers think options can only be a certain way and not modified. Any electronic car option that offers more than the single option should be modifiable & saveable in my book.
Thank you.
