2006 Jeep Commander: the check engine light comes..park

This answer was rated:

What does it mean when the check engine light comes on with the message "service park assist system" for a 2006 Jeep Commander
Welcome to JA. Most of the time this is caused when one of the sensors on the rear bumper stops working.

Can you go into more detail
Yes if the computer does not see that all the sensor are working then it will turn this message on to let you know that you will need to look behind you because the system may give false info.
