DIY video bypass safe?

[AJ170]

On another forum, there's a DIY guide on which wires to cut in the radio to enable video playback and navigation settings while driving (DIY version of the prestigious radio/NAV crack)

My worry is, will this affect future diagnostics with my car if a speed sensor goes out or something?

in order to do this you cut the speed sensor wire and leave it cut then cut the parking brake wire and ground it.

Would adding a switch to the speed sensor and parking brake wire be a safer route for possible future diagnostics?



It reads to me like the speed sensor wire is a on/off switch and not reading the speed of the car (in the secret menu, there's a digital tachometer)

If this is deemed not to affect future diagnostics, then I will do this myself and post a DIY guide.

I was wondering why this was never posted here, I was thinking maybe there's a reason, and this has unforeseen effects.

I've done that for several Nissan customers with AV setups similar to your M, and it's harmless as long as you snip the wire at the AV Unit and not at the cluster. The speed signal is generated by the cluster based on CANbus speed inputs from the TCM and/or ABS, so the signal to the AV is secondary and doesn't affect any critical operations. You might get codes in the BCM, but it shouldn't turn on any lights. It will, however, disable speed-sensitive volume in your audio system.

OK cool thank you, I'll do this next week and post a DIY write up with pics for others.

While I'm writing you, I want to be able to turn off my Canadian M37 lowbeams during the day, I read in order to do this i have to change the VIN in my BCM with Consult 3 Pro, will this have any weird effects aside from possible registration issues if I don't change it back? I read i need to find an American M37 with the same packages as me to flash it over. Idk if it will affect my keys they didn't say.

Nissan BCM's deliberately aren't reprogrammable for security reasons, they're the gatekeeper for the I-Key system. The pre-'17 models don't typically store the VIN in the BCM, the ECM does that. I'm pretty sure you need to replace the BCM with a US model, configure it for your ride, and reregister the keys.

This is quite common topic in Japanese forum that only used one addintial wire to grounding without cutting any exisitng wires.
It is worth to try.

The steps were described in Japanese but I believe Google translation will help:
