U0592 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. 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.

Likely causes

Selector module B electronics or position sensing faulty
Bus wiring or gateway path between selector and transmission controller disturbed
Software of selector, gateway or TCM out of date

Symptoms

  • Vehicle will not shift out of Park
  • Transmission fault message in the cluster
  • Restricted gear selection
