al303 Posted Monday at 02:30 PM Report Share Posted Monday at 02:30 PM (edited) Sorry if this is posted in the wrong forum, I could not find a steering sub-forum. About 3 days ago my wifes 2018 Edge Titanium AWD displayed an "Adaptive Steering Fault - Service Required" message at startup. The steering wheel is now at about a 40 degree angle to drive straight. I ran Forscan, and have attached (I hope) the findings. I've tried resetting the fault through Forscan without success. Has anyone had this issue, or know of a fix for this, looks to be expensive, problem? Any help would be greatly appreciated, Al Edited Monday at 03:33 PM by al303 Quote Link to comment Share on other sites More sharing options...

Haz Posted Monday at 08:08 PM Report Share Posted Monday at 08:08 PM @al303: Excerpts from 2018 Edge Workshop Manual, with emphasis added, and full sections attached below as PDF documents... Placing your device cursor over underlined acronyms may yield full-words descriptions of the acronyms. Adaptive Steering Overview The adaptive steering system provides steering assist to the driver by dynamically changing the steering ratio between the steering wheel and the road wheels, thereby reducing the number of steering wheel turns required to turn the road wheels. This is accomplished through the use of a motor, worm gear and toothed hub. All adaptive steering system components are inside the steering wheel, behind the driver air bag. Adaptive Steering System The SECM is self-monitoring and is capable of setting and storing Diagnostic Trouble Codes (DTCs). Depending on the nature of the DTC , the SECM may engage the adaptive steering lock and may send a request to the IPC to illuminate the adaptive steering system warning indicator and display a message in the message center alerting the driver of a potential adaptive steering system concern. The warning message is sent over the HS-CAN2 to the GWM where it is converted to a HS-CAN3 message and forwarded on to the IPC over the HS-CAN3 . Adaptive Steering Lock The adaptive steering system is designed with a locking device. While the lock is engaged, the steering system is set to a fixed (1:1) steering ratio. A sound may be heard when the vehicle is started or shut off as the lock is disengaged or engaged and a slight movement of the steering wheel may be noticed while the locking action is taking place. If the vehicle loses electrical power or the SECM detects a fault while driving, the lock is engaged. Extreme operating conditions may also cause the SECM to engage the lock. This strategy prevents overheating and permanent damage to the adaptive steering system. Typical steering and driving maneuvers allow the system to cool and return to normal operation. While the lock is engaged, it is possible the steering wheel may not be straight when the vehicle is driving straight ahead and the driver may notice the steering wheel angle or "clear vision" may be off-set. The locking solenoid also engages when the ignition is set to ON and the driver door is closed, this prevents the steering wheel from turning unnecessarily while the system is off and affecting steering wheel clear vision. The locking solenoid disengages once the engine is started. Adaptive Steering System - Diagnosis and Testing PINPOINT TEST K: STEERING LOCK CONCERN Introduction Normal Operation and Fault Conditions With the ignition ON, the SECM monitors various inputs to detect if a fault is present. DTC Fault Trigger Conditions DTC Description Fault Trigger Condition C1039:7F Active Front Steering (AFS) Lock: Actuator Stuck Off Sets when the SECM cannot activate the adaptive steering lock at engine start. C1039:92 Active Front Steering (AFS) Lock: Performance Or Incorrect Operation Sets when the SECM detects the adaptive steering lock fails the unlocking test. C1039:94 Active Front Steering (AFS) Lock: Unexpected Operation Sets when the SECM detects the adaptive steering lock fails the integrity test or the locking disc calibration test. C200D:28 Motor Rotation Angle Sensor: Signal Bias Level Out Of Range/Zero Adjustment Failure Sets when the SECM detects the adaptive steering motor angle sensor signal is outside the normal operating range or if the sensor is incapable of learning the center position. C200D:62 Motor Rotation Angle Sensor: Signal Compare Failure Sets when the SECM detects the adaptive steering motor angle sensor fails to learn the center position. U2001:92 Reduced System Function: Performance Or Incorrect Operation Sets due to a restraint airbag impact event or a fuel cutoff event. Due to the fault setting conditions, the installation of a new steering wheel and SECM are not covered under the vehicle warranty. Subsequently, a RVC is not provided for component replacement due to this DTC. U3000:46 Control Module: Calibration/Parameter Memory Failure Sets when the SECM detects an internal fault. U3000:49 Control Module: Internal Electronic Failure Sets when the SECM detects an internal fault. U3000:61 Control Module: Signal Calculation Failure This DTC sets due to an incomplete or an improperly performed trim routine. U3000:9A Control Module: Component or System Operating Conditions Sets when the SECM detects an internal fault. Possible Causes Incorrect sensor input SECM (steering wheel) K1 CARRY OUT THE SASM (STEERING ANGLE SENSOR MODULE) MODULE RESET ROUTINE NOTE: If present in any module, diagnose DTC U3003:16, U3003:1C or U3003:68 before diagnosing DTC C1039:7F, C1039:92 or U3000:49. Ignition ON. Using a diagnostic scan tool, carry out the SASM Module Reset routine. No VCM Recognized Ignition OFF. Start the engine and wait 20 seconds for the SECM to wake up and test the adaptive steering system. Ignition ON. No VCM Recognized Is the original DTC from the DTC Fault Trigger Conditions table retrieved again? Yes GO to K2. No For all other DTCs , REFER to the SECM DTC Chart. If no DTCs are present, the concern is not present and the system is operating correctly at this time. K2 CHECK FOR SASM (STEERING ANGLE SENSOR MODULE) DTCS No VCM Recognized Are any SASM DTCs present? Yes DIAGNOSE the DTCs present. REFER to Section 206-09 in the Workshop Manual. No GO to K3. K3 VERIFY ALL WIRING CONNECTIONS Ignition OFF. Disconnect all SECM electrical connectors. Using a good light source, inspect all disconnected electrical connectors for the following: corrosion - install new connector or terminal and clean the module pins damaged or bent pins - install new terminals or pins pushed-out pins - install new pins as necessary spread terminals - install new terminals as necessary Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals? Yes For all others: GO to K4. No REPAIR the connector or terminals. Refer to Wiring Diagrams Cell 5 for schematic and connector information. K4 CHECK FOR CORRECT SECM (STEERING EFFORT CONTROL MODULE) OPERATION Connect all SECM electrical connectors. Make sure they seat and latch correctly. Operate the system and determine if the concern is still present. Is the concern still present? Yes INSTALL a new Steering Wheel (SECM) assembly. CHECK OASIS for any applicable service articles: TSBs , GSB, SSM#2 or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SECM (part of the steering wheel). REFER to Section 211-04 in the Workshop Manual. Generate RVC only works in single-step view No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues. K5 CHECK FOR CORRECT SECM (STEERING EFFORT CONTROL MODULE) OPERATION Connect all SECM electrical connectors.
