P0930 Gear Shift Lock Solenoid Control Circuit Low

P0930 indicates the gear shift lock solenoid control circuit is low. The control path is grounded, missing voltage, or below expected electrical range.

Diagnostic boundary

A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.

Do not force the shifter out of park as diagnosis; test the low solenoid circuit and brake input first.

Useful checks before replacing parts

Measure shift-lock solenoid control voltage, feed supply, ground integrity, resistance, and current draw while checking for short-to-ground faults.
Inspect fuse feed, brake switch data, console harness, connector terminals, liquid damage, and module driver output.
Compare the low circuit event with brake pedal operation, park status, shift-lock release, and freeze-frame voltage.
