P0513 is a diagnostic trouble code that indicates an issue with the start enable signal not being sent by the Drive Authorization System (DAS). This code typically means that the engine will not start, as the DAS is preventing the engine from starting.
Here are some steps that can help you fix the issue:
Check the key fob battery: A weak or dead battery in the key fob can cause communication issues with the DAS. Replace the key fob battery if it is weak or dead.
Check the wiring: Inspect the wiring harness that connects the DAS to the engine control module (ECM) for any visible damage, such as cracks or breaks in the insulation. Also, check the connectors for corrosion or debris. Repair or replace any damaged wires or connectors.
Check the DAS module: Use a diagnostic scanner that can read fault codes and access the DAS module's data to check if there is any malfunction. Replace the DAS module if it is found to be faulty.
Check the ECM: Check if the ECM is receiving a signal from the DAS by monitoring the DAS output on the diagnostic scanner. If there is no output, the ECM may be malfunctioning. Replace the ECM if it is found to be faulty.
Check the fuses: Check the fuses related to the DAS system for any damage or blown fuses. Replace any damaged fuses.
Perform a road test: After performing the repair, take your vehicle for a road test to ensure that the fault code is not triggered again.
If the above steps do not resolve the issue, it is recommended to take your vehicle to a certified mechanic or dealership for further diagnosis and repair.
