U0230Lost Communication With Rear Gate Module

  • Generic OBD-II code · Network
How the car detects it
U0230 means the rear gate module, which runs a powered liftgate or tailgate with its drive, latch, cinch motor and pinch detection, has dropped off the bus. Toyota bulletin T-SB-0038-15 (Highlander and Highlander HV 2008-2013) names U0230 together with B2222 when the power back door reverses at the end of its travel or clunks at the striker, and gives a hinge and hatch inspection and repair. GM PI PIT5422 (Equinox, Terrain 2010-2015) blames moisture and corroded terminals in connector X901, high on the liftgate, for U0230 and other low speed LAN codes. A Chrysler STAR case (S1908000143) found it as Power Liftgate Module code beside chafed wiring at the right B-pillar. Saab lists the slot as Liftgate Control Module. Power operation of the gate fails; no MIL.
