DETECTION CONDITION 
  • C0051:2F
    • BCM detects error in a combination of signals from each sensor (A, B, C, Z).
  • C0052:11, C0053:11, C0054:11, C0055:11
    • Short to ground in steering angle sensor signal circuit.
  • C0052:13, C0053:13, C0054:13, C0055:13
    • Open circuit in steering angle sensor signal circuit.
FAIL-SAFE FUNCTION 
  • Sends the steering angle 0° data to the DSC HU/CM.
POSSIBLE CAUSE 
  • Steering angle sensor connector or terminals malfunction
  • BCM connector or terminals malfunction
  • Short to ground in wiring harness between the following terminals:
