U0060 code meaning
Vehicle Communication Bus D (-) Open
What U0060 means
U0060 stands for a break in the (-) line of Vehicle Communication Bus D, CAN-Low on a two-wire CAN such as Bentley's private chassis network. Nodes cut off by the break still see CAN-High move, but a high-speed receiver judges only the voltage difference between both wires, so frames from the other side become unreadable to them. NXP notes that a high-speed transceiver has no way to detect a line interruption itself, which leaves time-outs and missing acknowledgements as the evidence. NXP also designed the wake-up detection of its TJA1041 so that a CAN-Low interruption causes no unwanted wake-up while the bus goes to sleep. No manufacturer documents U0060 publicly. Test CAN-Low continuity between the modules, starting with connectors recently opened.
U0060 at a glance
- Check engine lightUsually not
- Emissions testNot an emissions code
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 5 hours
- Clears after repairWhen cleared with a scanner
Symptoms of U0060
- Functions of modules beyond the break fail
- Lost-communication codes for individual modules on Bus D
Common causes of U0060
- Most likely(-) wire of Bus D broken in the harness
- PossibleConnector not fully latched after work on the vehicle
- Less likelyCorroded terminal opening the (-) line
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of U0060 means
| U | Network system: communication between the control modules (CAN bus). |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 60 | The exact fault in that area. |
What to do next
- Note U0060 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about U0060
What does U0060 mean?
U0060 means "Vehicle Communication Bus D (-) Open". U0060 stands for a break in the (-) line of Vehicle Communication Bus D, CAN-Low on a two-wire CAN such as Bentley's private chassis network. It is a generic code, so it means the same on every make.
Is it safe to drive with U0060?
U0060 does not normally turn on the check engine light by itself. Watch for the symptoms above and have it checked soon.
Will U0060 fail an emissions test?
U0060 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is U0060 to fix?
Difficulty: hard. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will U0060 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
