P0930Gear Shift Lock Solenoid/Actuator Control Circuit A Low
- Generic OBD-II code · Powertrain
- How the car detects it
- The voltage on control circuit A of the shift lock solenoid stays below the expected level, typically a short to ground or a driver output pulled low. No manufacturer documents this code publicly. FCA uses the sibling codes on the same brake transmission shift interlock (P0928 BTSI Control, P0931 on the 2016 Grand Cherokee). CARB requires output components to be checked for circuit continuity and shorts, while a safety-only system may be exempt, which is why these faults often do not light the MIL. P0928 is the open, P0931 the high fault, P0929 the plausibility fault of circuit A; P092C is the low fault on circuit B. Depending on the design the selector stays locked in Park or is no longer locked at all.
- What you may notice
- Selector lever stuck in Park although the brake is pressed

- Shift lock override slot needed to move the lever
- Likely causes
- LikelyShift lock control wire chafed through to ground in the console or under the carpet
- PossibleShorted turns in the shift lock solenoid coil
- RareSpilled liquid in the shifter area causing leakage to ground
- Repair
