U0060 — Vehicle Area Network (VAN) Data Bus D (-) – Open Circuit #

Note: The description of code U0060 may vary depending on the vehicle manufacturer (OEM). Always refer to your OEM’s documentation for exact terminology.

• Vehicle Area Network Data Bus D Negative Circuit Open (General/SAE)
• VAN Data Bus D (-) – Circuit Open (Peugeot/Citroën/PSA)
• Communication Bus D Line Open Circuit (Honda/Acura)
• CAN Data Bus D Low Circuit Open (Renault/Nissan)

Summary of DTC U0060 #

The U0060 code signals a communication issue on the Vehicle Area Network (VAN) Data Bus D. The VAN bus is a specialized wiring system that enables various electronic modules in your vehicle to exchange information. An “open circuit” means there is a break or disconnection in the data bus D’s negative wire, preventing proper data flow. This hampers module-to-module communication, potentially affecting everything from engine management to dash displays. While the vehicle may still start, certain systems may be unresponsive or display warning lights. Prompt attention is crucial, as unresolved network faults may lead to cascading electrical issues.

Common Symptoms for Code U0060 #

When the U0060 fault is present, your vehicle may exhibit a variety of electronic glitches—some subtle, others more obvious. Since modules rely on network data, expect erratic or absent information from systems connected to Bus D. Typical symptoms include:

• Illumination of the Check Engine Light or other warning indicators
• Loss of functionality in affected control modules (e.g., ABS, transmission, infotainment)
• Unresponsive or intermittent instrument cluster displays
• Failure of electronic accessories tied to the VAN network
• Communication errors when scanning with a diagnostic tool
• Occasional “No Communication” messages on diagnostic equipment

Probable Causes for Code U0060 (From Most to Least Common) #

A data bus open circuit often results from physical or electrical issues disrupting the flow of information. Based on field experience, the most frequent causes of U0060 are:

1. Damaged, cut, or corroded VAN Data Bus D wiring
2. Poor or loose connectors at module or harness junctions
3. Faulty electronic control module (ECM/TCM/BCM) on Bus D
4. Short to ground or open connection within the harness
5. Aftermarket accessory or improper wiring tap affecting the bus
6. Water intrusion or oxidation at terminals or connectors

Step-by-Step Diagnostic Guide for U0060 #

Diagnosing a network open circuit requires systematic electrical checks and logical isolation. Follow these steps to pinpoint the root cause of U0060:

1. Connect a professional scan tool and confirm the presence of U0060. Check for other communication-related DTCs.
2. Visually inspect the VAN Data Bus D wiring and connectors for physical damage, corrosion, or loose pins.
3. Use a wiring diagram to trace the Data Bus D circuit and identify all connected modules.
4. With the ignition off, disconnect the battery and test the continuity of the Bus D (-) wire from end to end. Look for open circuits.
5. Check for short-to-ground conditions or resistance at relevant connectors.
6. Reconnect modules one by one, monitoring for return of communication with each step.
7. If the wiring checks out, substitute a known-good control module (if possible) to rule out internal faults.
8. Clear the codes, road-test the vehicle, and recheck for recurrence.

Possible Repairs for Code U0060 #

Depending on the diagnosed cause, repairs for U0060 will focus on restoring integrity to the VAN Data Bus D circuit. Typical solutions include:

• Repairing or replacing damaged Bus D wiring (splices, soldering, or harness replacement as needed)
• Cleaning or replacing corroded or loose connectors
• Securing and protecting connection points with dielectric grease or weatherproofing
• Repairing or replacing a faulty control module (after confirming with OEM-level diagnostics)
• Removing or correcting improper aftermarket installations affecting the network
• Addressing water leaks or moisture intrusion at connectors

Is It Safe to Drive with Code U0060? #

Driving with code U0060 is not recommended until the issue is properly diagnosed and resolved. While the vehicle may start and run, key safety and control systems could be compromised or disabled. Unresponsive modules may affect braking, stability, or even starting in some cases. Continuing to drive with a network fault also risks further electrical damage or data corruption. If you must move the vehicle, do so only for servicing and at low speed.

Vehicles Most Commonly Affected by U0060 #

The U0060 code is more prevalent on European models and vehicles using VAN or CAN-based communication networks. However, it can be encountered across various brands as electronic systems become more complex. Vehicles most often reporting this DTC include:

• Peugeot (208, 308, 3008, 508)
• Citroën (C3, C4, C5, Berlingo)
• Renault (Clio, Mégane, Scenic)
• Nissan (Qashqai, X-Trail, Juke)
• Honda/Acura (Depending on network architecture)
• Fiat and Opel/Vauxhall models with PSA architecture

Common Mistakes & Best Practices for U0060 #

Network faults can be tricky, and it’s easy to misdiagnose or overlook details. Keep these pitfalls and recommendations in mind:

• Don’t replace modules blindly. Always verify wiring and connections first.
• Avoid probing connectors with sharp tools that may damage terminals.
• Always disconnect the battery before testing or repairing network wiring.
• Consult reliable wiring diagrams and OEM repair procedures.
• Be wary of water leaks—moisture intrusion is a frequent culprit.
• Aftermarket devices (alarms, stereos, trackers) are common sources of bus faults—inspect any non-OEM wiring.

Quick FAQ for Code U0060 #

Here are answers to some of the most common questions about the U0060 DTC:

• Q: Can a dead battery or jump starting cause U0060?
  A: Yes, voltage spikes or improper jump starting can disrupt network communication or damage wiring, triggering U0060.
• Q: Will clearing the code with a scan tool fix the problem?
  A: No. The code will return if the underlying open circuit is not repaired. Always address the root cause before clearing codes.
• Q: Is U0060 related to the CAN bus?
  A: While similar, the VAN bus is a distinct communication protocol found mainly in PSA vehicles. However, the principle of data interruption is shared with CAN-based systems.
