J6 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) MODULE YAW RATE VALUE (YAW_RATE) PID (PARAMETER IDENTIFICATION)
NOTE: The vehicle must be on level ground and at a complete standstill. Any vehicle movement results in false values for this test.
Ignition ON. Using a diagnostic scan tool, monitor the ABS module YAW_RATE PID.
Is the YAW_RATE PID value between -0.05 and 0.05?
