After acquiring a 2015 Huracan LP-610-4 with a seized engine, the vehicle underwent extensive repairs, including an engine replacement. While many fault codes cleared after the new engine was installed, several persistent issues require further diagnostics and solutions using VCDS (VAG-COM Diagnostic System). This article focuses on troubleshooting the remaining Huracan Vcds error codes related to steering assist and suspension systems.
Addressing Steering Angle Sensor Errors with Huracan VCDS
A prominent issue identified by the Huracan VCDS scan is related to the Steering Angle Sensor (G85). Error code 00778 – Steering Angle Sensor (G85), with the sub-code 005 – No or Incorrect Basic Setting / Adaptation, indicates a need for calibration. This error cascades through other systems, causing further problems. Addressing this fundamental issue is crucial. The VCDS software allows access to perform the necessary basic setting and adaptation procedures for the G85 sensor. This involves specific steps outlined in the official Ross-Tech VCDS documentation and requires careful execution. Additionally, error code 7150 – Implausible Data Received from Steering Angle Sensor Module (G85), found in both Engine modules (Address 01 and 11), further emphasizes the importance of correctly calibrating the G85. This implausible data likely stems from the incorrect basic settings.
Investigating Electronic Damper Control Module Communication
Another significant concern highlighted by the Huracan VCDS scan is the lack of communication with the Control Module for Electronically Regulated Dampers (J250). Error code 00471 – Control Module for Elect. Regulated Dampers (J250), with sub-code 004 – No Signal/Communication, points to a potential wiring issue, a faulty control module, or a problem with the power supply to the module. Replacing the module with a known good unit did not resolve the issue, suggesting the problem lies elsewhere. Further diagnostics using Huracan VCDS should focus on checking the relevant fuses and relays for the J250 module. Locating a comprehensive fuse/relay diagram for the rear fuse panel and engine bay fuse panels is critical to this diagnostic process. This diagram will help pinpoint the exact fuses and relays responsible for powering the J250, allowing for thorough testing and replacement if necessary. Additionally, visually inspecting the wiring harness for any damage or disconnections related to the J250 is recommended.
Conclusion: Utilizing Huracan VCDS for Comprehensive Diagnostics
Resolving the remaining Huracan VCDS error codes requires a systematic approach. Addressing the Steering Angle Sensor (G85) calibration issue is paramount, as it impacts other systems. Thoroughly investigating the power supply and communication lines to the Electronic Damper Control Module (J250) is crucial. Utilizing the Huracan VCDS system along with official documentation and wiring diagrams will be essential in pinpointing the root causes and implementing effective solutions.
