A recent no-start condition in a VW resulted in a series of fault codes, most notably the VCDS fault code 01317. This code indicates “Control Module in Instrument Cluster (J285) 004 – No Signal/Communication.” This article will analyze the diagnostic process using VCDS (Vag-Com Diagnostic System) and explore potential solutions for this common issue. The vehicle exhibited the following symptoms: starting then immediately dying, intermittent immobilizer and airbag warning lights, and a complete loss of instrument cluster function. A new battery and relay 460 (VW 1K0951253A) were installed prior to the diagnostic scan, attempting to address the no-start issue.
Initial VCDS Scan: Cluster OFF/No Start
The first scan, performed with the instrument cluster off and the car in a no-start condition, revealed numerous fault codes across multiple modules.
Address 03: ABS Brakes
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/Communication
Address 08: Auto HVAC
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/Communication
Address 09: Cent. Elect.
01341 - Control Module in Instrument Panel On Comfort CAN (J285) 004 - No Signal/Communication
Address 15: Airbags
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/Communication
Address 19: CAN Gateway
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/Communication
Address 1C: Position Sensing
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/Communication
Address 55: Headlight Range
01317 - Control Module in Instrument Cluster (J285) 004 - No Signal/CommunicationThe recurring 01317 fault code across these modules points to a central communication problem with the instrument cluster (J285). Other significant codes included U0155 (No Communication with Instrument Cluster) in the engine module and various immobilizer-related codes. The “Cannot be reached” status for modules 17 (Instruments) and 25 (Immobilizer) further solidified the suspicion of a faulty instrument cluster or a communication breakdown on the CAN bus.
Second VCDS Scan: Cluster ON
After managing to start the vehicle, a second scan was conducted with the instrument cluster operational. While some modules cleared their 01317 fault, the code persisted in several systems. Notably, module 17 (Instruments) now reported “Sporadic communication error,” suggesting intermittent connectivity issues.
Post DTC Clear Scan
Following a Diagnostic Trouble Code (DTC) clear, most fault codes were erased. However, the engine module still logged P0506 (Idle Control System RPM Lower than Expected), P2181 (Performance Malfunction in Cooling System), U0155 (No Communication with Instrument Cluster), and P0513 (Incorrect Immobilizer Key). These persistent codes, even after clearing, indicate underlying problems that require further investigation. While the 01317 errors were cleared, the initial prevalence of this code suggests the root cause might not be fully resolved. Further diagnostics should focus on the instrument cluster’s power supply, grounding, and CAN bus connections. Inspecting the wiring harness for damage or corrosion is crucial. A potential solution might involve replacing or repairing the instrument cluster itself. Additionally, addressing the remaining engine and immobilizer fault codes is necessary for complete vehicle functionality.
