N54 Motiv Reflex MHD001 - CAN Sensor 1 Timeout

[lxzndo]

I’ve seen there was a thread for this topic already, but it seems I’m having an issue that they maybe are not. I’ve gone over my wiring and it looks all good, and have been trying to get in contact with Jake to have him take a look through anydesk which may happen tomorrow, but I just want y’all’s opinion on this. I want to get my car tuned because all of this potential is currently being wasted when I know what my car could be doing. Car is reading nothing for Motiv, but motiv is on and apparently working. Car is getting the MHD 001 Code, which keeps the car in a low power mode until resolved.

if you have the correct patch applied to the Motiv [you have to enable the canbus and then write that bin using Tunerpro], then it's 99% of the time canbus wires. Those wires are very sensitive and require a very solid connection.

I agree. If you are using the supplied PosiTaps, you have to make completely sure that those connections are tight and centered. Verify the connections with a multimeter with a connectivity buzzer.

I personally have gotten this error a few times, and what resolved it was making sure the needlepoint of the positap is hitting the copper of the line it's penetrating. It is common for the needlepoint to pierce the wire insulation off-center and not actually make electrical contact.

Here's some more troubleshooting from the Motiv Reflex+ User Manual:
