A P2544 indicates there is a malfunction with signal input in the powertrain control module (PCM) or one of its related control modules.
The P2544 code means an input signal malfunction has been detected in a powertrain-related control module, most notably (but not limited to) the transmission control module and PCM itself. Problems with electrical input signals will affect the vehicle's drivability.
A signal request malfunction may be logged multiple times in a row before a P2544 code is registered. In many cases, the problem lies with the PCM itself, which may be hampered by a faulty driver. Faulty and broken wiring may also be to blame for a P2544 code.
A P2544 code is most easily identified by logging the code on a OBD-II scanner. The drivability of the vehicle is often affected. Weaker acceleration and engine efficiency are also common concerns in a P2544 scenario.
All wiring and connectors related to the PCM and torque control converter should be inspected thoroughly, to rule out any issues with the hardware itself. Electric connectors and wires should be tested individually in order to pinpoint the source of the P2544 problem.
The electrical signal problem may cause other problems. When these resulting symptoms are misdiagnosed as the problem itself, otherwise good hardware may be replaced without a purpose. Any electrical or software-based issue should be addressed before moving onto concerns with the hardware.
A P2544 code has the potential to seriously affect a vehicle's driving performance. Although the issue is usually mild, more severe cases can result in the engine stalling.
Repairing a P2544 code should run the risk of damaging control modules. if this occurs, the vehicle will need to be reprogrammed. Because of this, a P2544 should only be approached if you have extensive knowledge in automobile electronics.
