System Tests: Notes
WARNING:
Deactivate air bag system before performing any service operation involving steering column components. See appropriate
AIR BAG RESTRAINT SYSTEMS article. Do not apply electrical power to any component on steering column without first deactivating air bag system. Air bag may deploy.
CAUTION:
Disconnect battery before disconnecting Generic Electronic Module/Central Timer Module (GEM/CTM) harness 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.
NOTE:
Complete entire pinpoint test related to symptom before replacing GEM/CTM.
