  • CAN-related DTCs (for both hybrids: CAN DTC C2243)

  • Intermittent no-crank/no-start

  • Erratic or harsh shifting

  • EPB and Hold lights illuminated intermittently

  • Key Off indicated after placing the selector lever into the “P” position and depressing the Start/Stop button. When this condition occurs, the “P” position is not indicated on the instrument cluster. 

Replace the inhibitor switch (available as P/N 42700 3B700QQK) and clear any DTCs.
