Radio doesn’t work after jump start or new battery
If your Chrysler vehicle has the MyGig REN or
REZ Radio, you MUST remove the 30A radio fuse (M12) located in the totally integrated power module (TIPM) in the engine compartment BEFORE disconnecting or reconnecting battery cables.
If you disconnect or reconnect battery cables with the fuse in place, the electrical spike can damage the radio. The radio may also be damaged if the current battery goes dead and you replace it without removing the fuse.
Trouble code U0184 after jump start or new battery installation
If the radio doesn’t work after a jump start or a battery cable disconnect/reconnect and you find a U0184 trouble code, it means the digital data bus has lost communication with the radio. The radio may have been damaged by the electrical spike or may be locked up. Try disconnecting the battery terminals with the M12 fuse in place. Touch the battery terminals together to drain the radio capacitors. Then reinstall the battery cables. If the radio works, the problem was simply logic lock. If it doesn’t, replace the radio.
