Hi,
I just bought a new-to-me 2019 Ram 2500 Tradesman with the 6.4L engine. Driving it home I got a message on the dash ‘Service Active Tuned Mass Module Soon’. No check engine light but the code scanner pulled these:
C008E ECU Internal Performance
C2129-17 Battery Voltage - circuit voltage above threshold
P0697 ECU Internal Performance
U0402 Implausible Data Received from TCM
I had my ram dealership check for recalls and tsbs but nothing showed up for these four codes. The battery tests good and has recently been replaced.
Has anyone seen these before or been able to diagnose the message that showed up on the dash about the ATMM?
