The P051300 error code typically shows a issue with the communication in between the VGS2-FDCT and the engine control system (ECU). This communication malfunction often causes a "Start allow not released" message, stopping the engine from beginning.
Usual Reasons For the P051300 Error
A number of aspects can contribute to the P051300 mistake and the " Beginning make it possible for not provided" message:
Malfunctioning VGS2-FDCT: The VGS2-FDCT system itself can malfunction due to inner component failure, software corruption, or electrical issues.
Circuitry Harness Problems: Damaged, rusted, or loose electrical wiring in the communication bus between the VGS2-FDCT and the ECU can interrupt signal transmission.
Canister Bus Issues: The Controller Area Network ( canister bus) is a network that permits numerous electronic control devices in the lorry to connect. Issues with the canister bus, such as a damaged CAN bus module or electrical wiring concerns, can hinder the VGS2-FDCT's communication.
ECU Problems: Sometimes, the ECU itself may be the source of the communication trouble.
Software Program Issues: Obsolete or corrupted software application in the VGS2-FDCT or ECU can cause communication errors.
Sensing unit Failures: Although much less common, a defective sensing unit related to the transmission or engine can in some cases trigger the P051300 code.
Detecting the P051300 Mistake
A systematic diagnostic method is crucial for identifying the origin of the P051300 error:
Analysis Check: A Mercedes-Benz analysis tool (XENTRY/DAS) is crucial for getting the kept fault codes and any associated motionless scene information. This data supplies beneficial Mercedes Start enable not issued Repair clues regarding the conditions under which the mistake took place.
Aesthetic Assessment: A detailed visual examination of the circuitry harness, ports, and the VGS2-FDCT device itself is needed to recognize any apparent indications of damages or loosened links.
CAN Bus Screening: Checking the CAN bus for proper communication and signal stability is important. This may involve utilizing a specialized CAN bus analyzer.
Part Screening: Individual parts, such as the VGS2-FDCT and ECU, may require to be checked to verify their functionality.
Software Inspect: Examining the software program variations of both the VGS2-FDCT and ECU is very important to ensure they are up-to-date and suitable.
Mercedes VGS2-FDCT P051300 Repair Work Solutions
The solution to the P051300 error depends on the underlying reason:
VGS2-FDCT Substitute: If the VGS2-FDCT unit is faulty, it will likely require to be replaced. This requires Mercedes VGS2-FDCT Programming and Coding to ensure the new system is effectively incorporated with the lorry's systems.
Electrical Wiring Harness Repair: Harmed wiring or adapters should be fixed or replaced.
Container Bus Repair: Concerns with the CAN bus need to be dealt with, which might entail changing defective modules or repairing electrical wiring.
ECU Repair or Replacement: In unusual instances, the ECU might require to be repaired or replaced.
Software application Update: Upgrading the software in the VGS2-FDCT or ECU can settle software-related communication issues.
Sensor Replacement: If a damaged sensing unit is recognized as the reason, it will certainly require to be changed.
