Problem overview

Some Mitsubishi Outlander Sport owners report experiencing a no-start issue following an accident, often accompanied by a P1590 error code indicating a TCU/ECM communication fault. These problems can be attributed to several factors, including a dead battery, particularly after exposure to extreme cold, which may trigger the P1590 code and prevent the vehicle from starting. Additionally, some owners have encountered starter motor malfunctions resulting from accident damage, hindering engine ignition. Relay malfunctions within the fuse box, caused by freezing or damage, can also contribute to the no-start condition. To resolve these issues, it is advisable for owners to check the battery's health, inspect the starter motor for any signs of damage, and verify the condition of the relays in the fuse box, replacing any that are faulty.
