Audible Warning Device: Application and ID
Central Timing Modules (CTMs) are equipped on the two-wheel drive vehicles without power windows. All other vehicles have a Generic Electronic
Module (GEM).
NOTE: CTM diagnostics are not compatible with the New Generation STAR (NGS) Tester. Instead, the diagnostics are internal to the module. The
diagnostic mode is entered by shorting two pins of the diagnostic connector together.
