Question about 2001 Plymouth Neon
It could be two different things:
P1648 Battery Condition Monitor (BCM) Module Communication Signal Circuit Problem
P1648 Motor Control Module (MCM) Communication Signal Circuit Problem
If you have disconnected yourbattery in the last 50 starts then this code would come up. Use an OBD II scan tool to reset it
