Unable to move shifter out of Park or delay to release Park (shift interlock engaged)
Shift lever stuck until manually overridden
Malfunction Indicator Lamp (MIL) or transmission warning may illuminate (varies by vehicle)
No clicking or activation sound from shift lock solenoid when commanding release
Possible intermittent loss of shifter function or only works after multiple attempts

Read DTCs and freeze‑frame data with a scan tool; note conditions when code set
Visually inspect wiring, connectors and harness along route to solenoid B for damage, corrosion, or disconnected plugs
Check fuses/relays associated with the shift lock and PCM power circuits
Backprobe the solenoid connector and measure for battery voltage and ground while commanding shift unlock with scan tool
Measure solenoid coil resistance with meter (ignition off) and compare to specification; look for open circuit
Check for proper ground continuity from solenoid ground to chassis/ground point

Connector supply voltage when solenoid commanded: near battery voltage (approximately 12 V with engine off; 13–14.5 V engine running)
Off state voltage: near 0 V or open (depending on driver type)
Solenoid coil resistance (typical range): usually a few ohms to a few dozen ohms (commonly ~2–35 Ω). Refer to vehicle spec — open = infinite Ω
Driver output may be low‑side switching or PWM; if PWM, frequency commonly tens to a few hundred Hz and duty changes with command
Expected behavior when commanded: measurable power at control pin and return to ground (or switch to ground), and solenoid actuates within 1–3 seconds

Confirm code and capture freeze‑frame/conditions with a scan tool. Note ignition state, battery voltage, and gear selection.
Visually inspect connectors, harness, and fuses for the shift lock solenoid B. Repair obvious damage or corrosion.
Verify fuse(s) and relay(s) for circuit feed are good. Replace if blown or suspected faulty.
With ignition OFF, disconnect solenoid connector and measure coil resistance between the solenoid terminals. If infinite/open, replace solenoid.
With connector connected and backprobed, measure supply voltage and ground at the solenoid while commanding unlock from a scan tool. If no command voltage, trace supply or ground as applicable.
If supply voltage present but PCM/driver output not switching, check continuity from PCM/driver to solenoid connector. Repair broken wiring or poor pins. Check driver output at module; if harness and connector are good but driver does not switch, suspect module fault.
If wiring and driver appear good, apply fused direct 12 V to solenoid briefly to confirm mechanical actuation. If it does not move or draws abnormal current, replace solenoid.
After repairs, clear codes and recheck by commanding shift lock function several times; road test and re-scan to confirm no return.
For intermittent faults, perform wiggle tests, use a lab scope to monitor PWM or driver waveform while commanding, or monitor live data for changes under vibration.

Wire chafed/insulation damaged near harness routing causing break
Connector terminal corrosion or pushed-out terminal at solenoid or harness connector
Solenoid coil has failed open (infinite resistance)
Fuse or relay for shift lock circuit is blown or contacts bad
Ground strap or ground point loose/corroded near transmission or body
