99jhawk Posted Monday at 06:07 PM Report Share Posted Monday at 06:07 PM Front airbag light on my 2018 SE came on unexpectedly a couple of weeks ago. Checked codes and came back with C0061:68-81 Lateral Acceleration Sensor and U3000:49-28 Control Module. As part of troubleshooting, I tried erasing the codes to see if they persisted, and they did. Didn't have time to troubleshoot, so I waited a week and tried again. Now the car is returning the same two codes along with (10) new ones. Not sure where to start troubleshooting, so before I post the laundry list of codes, I'm curious if anyone might offer some assistance? If so, I will post the full list of codes. I'd like to do a bit of troubleshooting myself, but I do have a feeling this problem may end up at the dealership. Thanks! 1 Quote Link to comment Share on other sites More sharing options...

Haz Posted Tuesday at 06:30 PM Report Share Posted Tuesday at 06:30 PM (edited) Welcome to the Forum @99jhawk! Introductory diagnostic descriptions from the 2018 Edge Workshop Manual for most of your Edge's listed Diagnostic Trouble Codes (DTCs) are shown below... I was unable to immediately locate B005:01-28, U3000:4A-28, and U2300:64-28 without knowing the module(s) exhibiting the DTC(s). Regardless of those three DTCs, your intuition to leave the diagnostic & repair tasks to a professional dealership technician is valid, based upon the general caution Ford offers when dealing with Supplemental Restraint System (SRS) issues: WARNING: Incorrect repair techniques or actions can cause an accidental SRS deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment. Good luck! Placing your device cursor over underlined acronyms may yield popup full-words descriptions of the acronyms. PINPOINT TEST L: OCS FAULTS REPORTED BY RCM Introduction Normal Operation and Fault Conditions The RCM is in constant communication with various control modules on the HS-CAN 2. One of those modules is the OCSM . The RCM continuously monitors the HS-CAN 2 for fault messages reported by the OCSM . The RCM also checks for the correct identification of the OCSM . If the RCM receives fault message(s) from the OCSM , it stores DTC B00A0:09, B00A0:4A, B00A0:63, B00A0:64 or B00A0:68 in memory and sends a message to the IPC to illuminate the airbag warning indicator. DTC Fault Trigger Conditions DTC Description Fault Trigger Condition B00A0:09 Occupant Classification System: Component Failure Sets when the RCM receives a message from the OCSM that a fault exists within the OCS. B00A0:4A Occupant Classification System: Incorrect Component Installed Sets when the RCM senses the OCSM is present but not configured. B00A0:63 Occupant Classification System: Circuit/Component Protection Time-Out Sets when the RCM receives 8 or more invalid states from the OCSM. B00A0:64 Occupant Classification System: Signal Plausibility Failure Sets when the RCM receives messages containing upper or lower data limits other than limits stored in memory. B00A0:68 Occupant Classification System: Event Information Sets when the RCM receives a message from the OCSM that indicates an OCS fault is present. Possible Causes OCSM DTCs OCSM RCM NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS . PINPOINT TEST AG: STABILITY CONTROL SENSOR EVENT INFORMATION FAULTS (C006X:68) Introduction Normal Operation and Fault Conditions The RCM provides the stability/traction control system with acceleration sensor data over the HS-CAN 2. In addition to transmitting the data, the RCM monitors this data internally to make sure that the data is within an expected range. If the data is outside of the expected range and a fault is detected, the RCM stores DTC C0061:68, C0062:68, C0063:68, C0064:68, and/or C0065:68 in memory. However, the RCM does not request that the IPC illuminate the airbag warning indicator when these faults are present. DTC Fault Trigger Conditions DTC Description Fault Trigger Condition C0061:68 Lateral Acceleration Sensor: Event Information A fault is indicated when the lateral acceleration sensor is transmitting data that is outside of the range expected by the RCM. C0062:68 Longitudinal Acceleration Sensor: Event Information A fault is indicated when the longitudinal acceleration sensor is transmitting data that is outside of the range expected by the RCM. C0063:68 Yaw Rate Sensor: Event Information A fault is indicated when the yaw rate sensor is transmitting data that is outside of the range expected by the RCM. C0064:68 Roll Rate Sensor: Event Information A fault is indicated when the roll rate sensor is transmitting data that is outside of the range expected by the RCM. C0065:68 Vertical Acceleration Sensor: Event Information A fault is indicated when the vertical acceleration sensor is transmitting data that is outside of the range expected by the RCM. C006A:68 Multi-axis Acceleration Sensor: Event Information A fault is indicated when the multi-axis acceleration sensor is transmitting data that is outside of the range expected by the RCM. Possible Causes Aggressive driving conditions or rough roads RCM mounting RCM WARNING: Incorrect repair techniques or actions can cause an accidental SRS deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment. NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS . PINPOINT TEST AR: RCM IDENTIFIED AS CAUSE OF FAULT Introduction Normal Operation and Fault Conditions The RCM monitors various inputs and communicates on the CAN . If the values received are out of range or not what should be expected, the RCM sets a DTC . DTC Fault Trigger Conditions DTC Description Fault Trigger Condition B0080:11 Driver Seat Belt Load Limiter Deployment Control: Circuit Short To Ground Sets when the RCM detects an incorrect configuration. B0080:12 Driver Seat Belt Load Limiter Deployment Control: Circuit Short To Battery Sets when the RCM detects an incorrect configuration. B0080:13 Driver Seat Belt Load Limiter Deployment Control: Circuit Open Sets when the RCM detects an incorrect configuration. B0080:1A Driver Seat Belt Load Limiter Deployment Control: Circuit Resistance Below Threshold Sets when the RCM detects an incorrect configuration. B0080:2B Driver Seat Belt Load Limiter Deployment Control: Signal Cross Coupled Sets when the RCM detects an incorrect configuration. B1193:00 Crash Event Storage Full and Locked: No Sub Type Information Sets when the RCM has detected a crash event. B142D:00 Pyrotechnic End of Life Activation Performed: No Sub Type Information Sets when the RCM has experienced a pyrotechnic activation event. U2101:00 Control Module Configuration Incompatible: No Sub Type Information Sets when the RCM detects an incorrect configuration. U2200:00 Control Module Configuration Memory Corrupt: No Sub Type Information Sets when the RCM detects an incorrect configuration. U3000:04 Control Module: System Internal Failure Sets when the RCM detects an internal failure. U3000:46 Control Module: Calibration/Parameter Memory Failure Sets when the RCM detects an internal failure. U3000:49 Control Module: Internal Electronic Failure Sets when the RCM detects an internal failure.

99jhawk Posted Tuesday at 11:39 PM Author Report Share Posted Tuesday at 11:39 PM @Haz Thank you for the workshop manual information. I edited the posting of codes to note that they all came from the Restraint Control Module as read from a MaxiDiag MD808 Pro. As for troubleshooting, the most I was planning on doing was verifying anything obvious with connectors and wiring, if they are easily accessible. I've taken an initial look at the connections/wiring under the front seats, but nothing seemed out of place. Would you happen to be able to provide any wiring diagrams and/or location information for any of the obvious sensors and/or connections? As you noted, caution is warranted regarding the SRS, so I don't plan to dig too deep, but don't was to miss something obvious (like a loose connector). Thanks! 1 Quote Link to comment Share on other sites More sharing options...
Haz Posted Wednesday at 04:54 AM Report Share Posted Wednesday at 04:54 AM (edited) To emphasize the importance of your Health and Safety awareness, the SRS Depowering and SRS Repowering procedures are included here and are also provided below as PDF documents... From the Workshop Manual's Anti-Lock Brake System (ABS) and Stability Control section, with emphasis added... Stability Control Sensors The stability control sensors for the vehicle dynamic system consist of the yaw rate sensor, lateral accelerometer, longitudinal accelerometer and roll rate sensor. The sensors are housed in the RCM which sends sensor information to the ABS module over the HS-CAN2 . If any of the sensors are defective, a new RCM must be installed. The yaw rate sensor measures the yaw angle which is the difference between the direction the vehicle is pointing when cornering and the direction the vehicle is actually moving. The longitudinal accelerometer measures the acceleration and deceleration of the vehicle as it moves forward and backward. The lateral accelerometer measures the force created when a vehicle corners that tends to push a vehicle sideways. The roll rate sensor measures the rate of rotation of the vehicle along the centerline of the vehicle from front to back. Lateral acceleration has 2 forms. The first is the centrifugal acceleration that is generated when the vehicle travels around in a circle. The second is the acceleration due to gravity. On level ground there is no lateral acceleration due to gravity. However, if the vehicle is parked sideways on a bank or incline, the sensor measures some lateral acceleration due to gravity, even though the vehicle is not moving. A professional dealership technician may use Ford Diagnostic and Repair System (FDRS) diagnostic scan tool connected to Ford's servers to likely run a VIN-specific Guided Routine (RCM) of PINPOINT TEST AG: STABILITY CONTROL SENSOR EVENT INFORMATION FAULTS (C006X:68) to determine if replacement of the RCM is indicated by the step-by-step Pinpoint Test results.

99jhawk Posted Wednesday at 11:30 PM Author Report Share Posted Wednesday at 11:30 PM @Haz Thank you for the additional information and the emphasis on working safely. It will take me a few days to digest and review what you provided and decide how far I want to pursue this on my own. Again, many thanks for the info! 2 Quote Link to comment Share on other sites More sharing options...
