2015 Dodge Charger R/T 5.7L (T EZH) 8-spd (8HP70) — 2C3CDXCT6FH915816
No Ignition Switch Operation
Bcm No Comm

Hello DN.

I have this 2015 Dodge Charger towed to my shop with customer complaint that vehicle stalled while driving (I personally do not believe his side of the story), I have communication with all modules except BCM even the ignition is off (can't turn it on) I then bypass Ignition Run Relay under hood to on to check for codes. I checked for CAN Network and its a clean.

I have no controls on door lock cycle, trunk, flasher, keyless remote (fob), I have checked power and grounds to BCM and Wireless Ignition Module.

Have anyone run into this problem before?

This has either an ignition node or a keyless ignition node, not a WIN module. In a nutshell the RFHub needs to see a response from the BCM at key on otherwise it can ignore the ignition input from the KIN/IGN. If there are no codes in the RFHUB and you do not see the ignition positions changing with the key/push button, than focus on the lack of BCM communication first.

Star Topology has several connections to the DLC instead of just the Gateway as in previous networks .Probably Radio and IPC so scanner communication remains a go and not handcuffed .. Does the FOB wake the bus up from sleep from 0volt flat line .
