U0592 code meaning
Invalid Data Received From Gear Shift Control Module B
What U0592 means
Shift-by-wire cars turn the driver's lever, dial or buttons into network messages; where two such units exist, or the selector is split from a park-lock unit, the second one is module B. U0592 says its messages arrive but carry an implausible selector position, a frozen counter or a bad checksum, so the receiver cannot rely on the requested gear. Land Rover's bulletin LTB00677 for the 2014 Range Rover Sport (index entry only) lists U0592-00 in the engine module next to U0402 from the transmission control switch, with a car that would not leave Park; the cause was communication between junction box and TCM. Mercedes names the partner code U0291 as a fault with the electronic selector lever module on its 8-speed DCT. Ford's 2024 summary checks gear shift module data without MIL on park-by-wire cars.

Symptoms of U0592
- Vehicle will not shift out of Park
- Transmission fault message in the cluster
- Restricted gear selection
Common causes of U0592
- Most likelySelector module B electronics or position sensing faulty

What each part of U0592 means

| 0 | Generic code: it means the same on every make (SAE standard). |
| 92 | The exact fault in that area. |
What to do next
- Note U0592 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 U0592
What does U0592 mean?
U0592 means "Invalid Data Received From Gear Shift Control Module B". Shift-by-wire cars turn the driver's lever, dial or buttons into network messages; where two such units exist, or the selector is split from a park-lock unit, the second one is module B. It is a generic code, so it means the same on every make.
Is it safe to drive with U0592?
Drive gently and only to a workshop. With U0592 the car can go into limp mode (reduced power) to protect itself.
Will U0592 fail an emissions test?
U0592 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 U0592 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. This is a job for a workshop.
Will U0592 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
