Symptom Chart
Diagnostics in this manual assume a certain skill level and knowledge of Ford-specific diagnostic practices.
REFER to: Diagnostic Methods (100-00 General Information, Description and Operation).
In most circumstances the GSM sets a DTC to help guide with diagnostics. Refer to the DTC Chart before using the Symptom Chart. The Condition column lists the vehicle condition. The Action column refers to a pinpoint test. Each pinpoint test lists the components that can cause the symptom and the action to take to diagnose that system. The components are listed in order of disassembly. Use the list of components and the required action to focus on disassembly inspections for the root cause of the concern.

Pinpoint Tests
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions The GSM requires an operating voltage between 9 and 16 volts. The GSM receives this voltage from the BCM and has a dual ground circuit. Excessive resistance or an open in one or more of these circuits, a discharged battery or a inoperative charging system results in the GSM setting a DTC . DTC Fault Trigger Conditions
