Code B2544 Chrysler Description
1. Performance - These are time out DTCs, meaning the system timed out waiting for the next switch in sequence to change state. When the PTCM does not get the state change in the expected amount of time, it assumes something may be wrong and stops any further top operation in that direction. Typically the pump will run for 10 second before it times out.
2. Circuit Low - These DTCs set for a circuit that stays active at all times, meaning the signal circuit to the specified switch is continuously grounded. This could relate to a short to ground on the signal circuit, a sticking switch, or even a mechanical issue not allowing the switch to become inactive.
3. Correlation - These DTCs specifically relate two switches in a subcomponent (deck lid, tonneau drive, header latch, etc.) of the convertible top system. Both of the specified switches will be active in one position of the subcomponent (extended, retracted, open, closed, etc.). The switch that will not change state while attempting to operate the convertible top system, is the most likely area for attention.
