Code B2542 Chrysler Description

The Convertible Top is fairly typical of convertible tops. There are three types of failures possible: Electrical failure (switches, wiring, motor, etc.), Hydraulic failure (fluid level low, leaks, pump internal, etc.), and Mechanical failure (binding roof, bent links, obstructions, etc.). Each type of failure mode will be rationalized by the power Top Control Module (PTCM) and labeled with a Diagnostic Trouble Code (DTC). The DTCs set by the PTCM can also be considered to have three types of failure modes:
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.
