Hello!
I recently had to swap out my TCM and foolishly believed a retailer who said the TCM was already programmed for my 2008 Infiniti EX35 AWD Journey. Clearly - it was not.
So now I need to reprogram the ECM in order to program my TCM; based on everything I have read so far (mostly here). This requires I establish a Zero-draw on the Electrical system with the ignition on. The challenge being the instrument panel and the map light - which are both always on.
How can I override these?
Also, is this the only/right way to program a blank TCM - and do I need Consult III if I am using a j-box?
Any insight I can get is more than I have had this far and appreciated. Thanks!
