• Ignition off
• Check the connectors for the brake control module (BCM) and the active yaw control sensor. Check for contact resistance and oxidation
• Ignition on
• Wait approximately 60 seconds
• Read off the status of the diagnostic trouble code (DTC).

  If the status of the diagnostic trouble code (DTC) is intermittent, the cause of the fault was probably contact resistance or oxidation in the connectors for the control module or the active yaw control sensor.

  Other information 

  • To disconnect the connector for the active yaw control sensor, see ACTIVE YAW CONTROL SENSOR, REPLACING
  • See Checking wiring and terminals .
