CAUTION:
Disconnect battery before disconnecting Generic Electronic Module (GEM) or Central Timer Module (CTM) connectors. Failure to do so will result in GEM/CTM storing erroneous codes and may also result in erratic operation of GEM/CTM after reconnecting. When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
