Normal Operation

WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.

The yaw rate sensor, lateral accelerometer and longitudinal accelerometer are contained in the Restraints Control Module (RCM). The RCM measures vehicle yaw rate and lateral acceleration and then sends the information to the ABS module along the dedicated Controller Area Network (CAN) bus. This CAN bus is used only for communication between the RCM and the ABS module. The information sent to the ABS module is used to help determine if the AdvanceTrac® system needs to be activated.

DTC DESCRIPTION TABLE

DTC Description Fault Trigger Conditions
  • C0061:28 - Lateral Acceleration Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure
 This DTC is set if the lateral acceleration sensor measures acceleration when the vehicle is not moving.
  • C0061:64 - Lateral Acceleration Sensor: Signal Plausibility Failure
 This DTC indicates that the lateral acceleration sensor is inconsistent with other acceleration sensor, steering wheel angle sensor and wheel speed sensor signals.
  • C0063:28 - Yaw Rate Sensor: Signal Bias Level Out of Range/Zero Adjustment Failure
 This DTC indicates that the yaw rate sensor is measuring rotation when the vehicle is not moving.
  • C0063:64 - Yaw Rate Sensor: Signal Plausibility Failure
 This DTC indicates that the yaw rate sensor is inconsistent with other acceleration sensor, steering wheel angle sensor and wheel speed sensor signals.
  • U0151:87 - Lost Communication With Restraints Control Module: Missing Message
 This DTC sets as a result of a loss of communication with the RCM over either the High Speed Controller Area Network (HS-CAN) bus or the dedicated CAN bus.
  • U0151:88 - Lost Communication With Restraints Control Module: Bus Off
 This DTC can set if either the dedicated CAN circuits are open, shorted to ground or shorted to each other. Other DTCs indicating missing messages or invalid signal from the RCM sensors can set as a result of a dedicated CAN bus fault.
  • U0452:29 - Invalid Data Received From Restraints Control Module: Signal Invalid
 This DTC indicates that one or more of the stability/traction control system sensors internal to the RCM have failed and the RCM is transmitting an "invalid data" message.

This pinpoint test is intended to diagnose the following:
