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 PCM sets a DTC to help guide diagnostics. Refer to the DTC Chart before using the Symptom Chart. The Symptom column lists the vehicle condition. The Possible Sources column lists a detailed vehicle condition. The Action column lists the action to be performed to determine the cause of the condition. Each action lists the components that can cause the symptom and the individual components in that system.

PINPOINT TEST R : DTC P0563|
Refer to Wiring Diagrams Cell 37 for schematic and connector information. Normal Operation and Fault Conditions The GSM module requires an operating voltage that is between 9 and 16 volts. 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. An overcharging condition in the charging system results in the GSM setting a DTC. This DTC may also set due to battery charging or vehicle jump starting events. DTC Fault Trigger Conditions

| R1 CHECK FOR HIGH VOLTAGE DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES | ||||||
Are any charging system Diagnostic Trouble Codes (DTCs) present in the PCM?
|
||||||
| R2 CHECK THE BATTERY VOLTAGE | ||||||
Is the battery voltage between 13 and 15.2 volts?
|
||||||
| R3 RECHECK THE GSM (GEAR SHIFT MODULE) FOR DTC (DIAGNOSTIC TROUBLE CODE) P0563 | ||||||
|
NOTE: If a GSM self-test is performed, the driver door must be closed and locked. A false P166B and/or P081F DTC sets if the driver door is opened or unlocked during the self-test.
Is DTC P0563 still present?

| R4 VERIFY ALL WIRING CONNECTIONS | ||||||
Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals?

PINPOINT TEST S : DTCS P07EC, P07ED|
Normal Operation and Fault Conditions The GSM contains 3 contacts beneath the center button. If one contact is not recognized by the GSM then DTC P07EC sets. DTC Fault Trigger Conditions

| S4 CHECK FOR CORRECT GSM (GEAR SHIFT MODULE) OPERATION | |||||||||
Is the concern still present?

PINPOINT TEST T : THE TRANSMISSION CONTROL SWITCH IS INOPERATIVE OR DOES NOT OPERATE CORRECTLY|
Refer to Wiring Diagrams Cell 30 for schematic and connector information. Normal Operation and Fault Conditions The transmission control switch is a momentary contact switch located on the center console. When the switch is pressed the contacts close sending a voltage signal to the PCM and notifies the module to disable the overdrive gear. The PCM sends a message over the MS-CAN to the IPC which illuminates the tow haul indicator light in the IPC. DTC Fault Trigger Conditions
