Start enable of DAS not sent (P0513)

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:

1. 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.

2. 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.

3. 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.

4. 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.

5. Check the fuses: Check the fuses related to the DAS system for any damage or blown fuses. Replace any damaged fuses.

6. 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.

Notes on CAN fault codes:CAN timeout fault
­
A CAN timeout fault code is set due to the absence of a CAN input signal.The cause of this may be not only the transmitter control
unit, but also the CAN networking.
­ For example:No CAN message was received from control unit A.
Bus OFF fault
­
A Bus OFF fault code is set, when the control unit cannot send a certain amount of messages to the CAN bus or the messages are
incomplete.The control unit then switches off for a short time from CAN bus.
­ For example:CAN controller: CAN bus OFF
Functional CAN fault
­
A functional CAN fault code is set because of an implausible CAN input signal.The cause of this is not the CAN networking, but the
transmitter control unit or its sensors.
­ For example:CAN signal 'A' from control unit B is implausible.
Notes on CAN faults that cannot be read out as fault codes.Bus wake­up event
­ An event that wakes up the bus without reason is designated a bus wake­up event.
­ The cause of this is not the CAN networking, but the transmitter control unit or its sensors.
­ Further possible causes of fault:
­ Magnetic fields caused by nearby high­voltage installations, railroad installations or power plants.
­ Magnetic fields can radiate on to lines and control units in rare cases and cause undefined behavior in the control units.
­ The special tool 'Star Diagnosis CANtool' can be used to log bus wake­up events, bus keepawake events and other signals.
Bus keepawake event
­
When a control unit keeps communication on the bus awake without reason, this is designated a bus keepawake event.2010 Mercedes Benz E 63 AMG Sedan (212.077) V8­6.3L (156.985)
