Symptom Chart: Vehicle Dynamic Suspension
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).
Condition | Possible Sources | Actions |
|---|---|---|
A module does not respond to the diagnostic scan tool | Fuse Wiring, terminals or connectors VDM concern | REFER to: Communications Network (418-00 Module Communications Network) . |
Message center displays, DRIVE CONTROL MALFUNCTION SERVICE REQUIRED | Diagnostic Trouble Codes (DTCs) present in the VDM | RETRIEVE and DIAGNOSE all VDM Diagnostic Trouble Codes (DTCs). |
Rough or harsh ride | Vehicle dynamic suspension system disabled | RETRIEVE and DIAGNOSE all VDM Diagnostic Trouble Codes (DTCs). If no Diagnostic Trouble Codes (DTCs) are present, REFER to: Suspension System (204-00 Suspension System - General Information, Diagnosis and Testing). |
Pinpoint Tests
P0562:16, P1794:18, U3006:2F
Refer to Wiring Diagrams Cell 41 for schematic and connector information.
Normal Operation and Fault Conditions
The VDM requires an operating voltage between 9 and 16 volts. The VDM receives this voltage from the BCM and has a single 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 VDM setting a DTC.
DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
P0562:16 | Battery Voltage Low: Circuit Voltage Below Threshold | This DTC sets in continuous memory if the voltage supplied to the VDM falls below 9 volts for more than 3 seconds. |
P1794:18 | Battery Voltage Circuit: Circuit Current Below Threshold | This DTC sets in continuous memory if the voltage supplied to the VDM falls below 9 volts for more than 60 seconds. |
U3006:2F Control Module Input This DTC sets in continuous memory if the power reset indicates an irregular
Power "A": Signal shutdown and power up has been detected. This is usually caused by a Erratic sudden loss of vehicle battery voltage due to an open circuit, a disconnected
