4. Ignition OFF, Remove the positive connection at the 12-volt battery.
5. Measure the resistance between the X3 connector and the battery positive connection.
锟斤拷If the resistance is greater than 1.0 ohm, repair the high resistance condition in the 12-volt circuit.
锟斤拷If the resistance is less than 1.0 ohm, replace the battery positive cable - control module to auxiliary BEC.
