I hoping to find a wire which is energized when the Dynamic Mode is activated. I do have a plan to utilize the LED in the gear selector module but the low voltage/current circuit complicates things a bit so I'm hoping I can find something a bit more direct in the CJB or ADCM areas. Does anyone happen to have any detailed diagrams on these two modules? Or know of a more elegant way to achieve this?

I'm not sure you'll find a wire anywhere with that signal on it. Dynamic mode is logical setting of the suspension, ECU and TCM. What you will see is an instruction on the canbus telling the modules to go into dynamic mode when you press the button, you might also see responses from the modules confirming their settings. The most elegant way is to find those CAN messages so you just need access to the bus and don't need to route about inside the gear selector module.

 

I though I'd share my findings. After buying a canny 7.2 from Cannylogic (recommend) I was able to both monitor CAN messages and then filter the messages relevant to Dynamic Mode activation. Messages had an address of 2c8. There are no messages with the address when the vehicle is off (although there are other messages). Messages show with this address when the vehicle is ON, they continue showing with a different/fixed value once Dynamic Mode has been enabled (LED lighted). Because there were 3 distinct modes I was also able to integrate a low power loop into the canny program.

Happy to help anyone else if they want to pursue this or any other type of CAN behavior.


CAN messages inflight. Relevant messages shows every 15ms

Can logic to energize 4 relays when specific value seen in data fields 4 and 5. Device sleeps for 1 second if 60ms elapse with no messages containing 2c8 address
