C006A covers a combined multi-axis sensor that delivers several motion axes from one device, the integrated form of the separate lateral, longitudinal, vertical, yaw and roll sensors; NHTSA's brake study and Bosch's six-axis IMU describe such units. The module treats the device as a whole and sets C006A for an internal fault, a failed self-test, lost communication or values that disagree across the axes. FCA documents C006A-49, internal electronic failure, on 2019-2020 RAM 2500 to 5500 trucks: the MIL comes on and bulletin 08-061-20 cures it with new ABS software; a RAM 2500 case report lists it as an active code in the ABS module. Stability, roll and related functions stay off while the fault is present; normal braking remains.

Likely causes

ABS module software fault (FCA bulletin 08-061-20)
Internal sensor fault or failed self-test
Harness or connector fault

Symptoms

  • Stability and roll control disabled
  • ABS/ESC warning lamp on
  • Multiple inertial faults at once
