Memory Backup Battery
The Lithium battery for backup of RAM memory is installed in a battery mounting clip on the
inside of the PCM faceplate. This battery is disconnected for shipment from the factory and must
be connected prior to installation of the module. When the PCM is stored for extended periods of
time, the battery should be disconnected, unless you wish to retain the program in RAM memory.
Order replacement batteries using catalog number IC693ACC301 (package of two).
