Ford GEM/CTM Module Block Diagram - Inputs, Outputs & Warning Indicators

This document is a block diagram illustrating the input/output architecture of a Ford GEM/CTM (Generic Electronic Module / Central Timer Module). The module is shown at center with Power In connections from Battery and GND at the top. On the left side, inputs are divided into two categories: Switched-to-GND inputs, which include the LH Door Open Warning Lamp Switch, RH Door Open Warning Lamp Switch, Key-in-Ignition Warning Switch, Safety Belt Warning Switch, and Restraint Control Module (RCM); and Switched-to-Battery inputs, which include the Key-Run/Acc Switch, Key-Run Switch, Key-in-Start Switch, and Headlamp Switch. On the right side, outputs drive indicator lamps: the Door Ajar Indicator and the Safety Belt Warning Indicator. At the bottom, a Diagnostics block connects to a diagnostics communication link (labeled 'DIAGNOSITCS COMMUNICATION LINK (IS0)', likely a typo for ISO). The diagram reference code GK9567-A appears in the lower right corner. A reader can learn which switches and modules feed the GEM/CTM, how they are grouped by switching type, and which warning indicators the module controls. No wire colors, connector pins, or fuse values are provided in this conceptual diagram.
