Diagnose check engine light found stored codes p0515 p0627 p0480 p0645 p0481 we're setting in the PCM. Also customer was complaining that vehicle was not shutting off when he was turned to the off position. I was able to duplicate the problem and found ignition feed to PCM was staying alive when it should have been off. This circuit also feeds all the other circuit for the codes that were setting codes. This vehicle will need the ignition switch replaced. That will fix the vehicle not shutting off and the check engine light.


2005 Liberty 3.7
Customer Concern: The vehicle does not shut off right away. Setting multiple trouble codes, P0480, P0481, P0627, P0645.
Average Reported Mileage: 84579
Tests/Procedures: 1. Repair the ignition switch feed to the Powertrain Control Module (PCM). This circuit should only have power when the key is in the "ON" or "CRANK" position.
