Make:
Jeep
Code:
B147E 92
Definition:
Lost Communication With Onstar
Cause:
Use the DTC Descriptor list above to determine the module which is not communicating.Some modules may not have internal protection for specific voltage outputs and may open a battery positive voltage or ignition voltage source fuse. If a voltage input fuse is open and no short is found in that circuit, ensure that no module output voltage circuit is shorted to ground before replacing the module.This diagnostic can be used for any module that should communicate with Class 2 serial data providing the vehicle is equipped with the option that uses that module.
Failure Type:
Performance or Incorrect Operation
This sub type is used for failures where the control module has detected that the component performance is outside its expected range or operating in an incorrect way.
