Jeep Liberty U0168 Fault Code: Car Starts but Won't Restart After 30 Minutes of Driving
My Jeep Liberty starts and runs fine initially, but after driving for about 30 minutes, when I turn it off for 5 to 10 minutes, it fails to restart. Only after waiting up to 10 minutes does it start again. This behavior has been consistent over several drives. The check engine light is on, and the OBD2 code U0168 is displayed. I'm concerned about potential issues with the CAN bus or vehicle control module.
The U016-than code U0168 in Jeep Liberty vehicles typically indicates problems such as: an open circuit in the CAN bus (+) or (-), a short to power in either CAN bus circuit, a short to ground in either CAN bus circuit, lack of power or ground to the VSCM (Vehicle Stability Control Module), or rarely, a faulty control module. It's important to diagnose these issues using a proper OBD2 scanner and check for continuity and voltage in the CAN bus wiring. For more details: U0168 Jeep Liberty fault code explanation.
