Hyundai won’t leave park

If the shift lever of a 2006 and later Hyundai Sonata or Azera, or 2007 and later Santa Fe, Elantra or Entourage won’t shift into or out of Park, follow this repair procedure:

  1. Attach a Hi-Scan Pro or GDS and select:

-          Vehicle

-          Automatic transaxle

-          Current Data

-          Brake switch

  1. Confirm that the “Brake Switch” reads ON when the brake pedal is depressed. If not, check the brake switch clearance according to the related shop manual. If the clearance is within specification, install a good know brake switch. Check fuses and related wiring as shown in the related ETM, page SD452-2. Refer to the appropriate model shop manual and remove the center panel. Disconnect the M01 connector to the ATM key lock control module. Go to the “Test Procedure.”
  2. Turn the ignition switch to the ON position. Check voltage at the pins according to the table shown here. If the voltages are correct, replace the ATM key lock control module
