Section 13 (Air Bag System (Diagnostics)): Rezero: List

WARNING: This page is about a different car, the 2022 Subaru WRX. However, it is still accessible from the selected car via links, so may be relevant.

Code	Contents	Causes	Action to take
0020H	Timeout due to unstable load	Airbag control module judged the current situation as error because the over-specified load change occurred during rezeroing.	Perform rezeroing again at a stable place where vehicle vibration hardly occurs.
0021H	FL sensor upper limit error	Rezeroing cannot be executed because the load value of FL sensor exceeds the upper limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0022H	FL sensor lower limit error	Rezeroing cannot be executed because the load value of FL sensor exceeds the lower limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0023H	FR sensor upper limit error	Rezeroing cannot be executed because the load value of FR sensor exceeds the upper limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0024H	FR sensor lower limit error	Rezeroing cannot be executed because the load value of FR sensor exceeds the lower limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0025H	RL sensor upper limit error	Rezeroing cannot be executed because the load value of RL sensor exceeds the upper limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0026H	RL sensor lower limit error	Rezeroing cannot be executed because the load value of RL sensor exceeds the lower limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0027H	RR sensor upper limit error	Rezeroing cannot be executed because the load value of RR sensor exceeds the upper limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0028H	RR sensor lower limit error	Rezeroing cannot be executed because the load value of RR sensor exceeds the lower limit of rezero adjustment range.	Check that the seat is in proper position and fixed securely, and perform rezeroing again. If the same code appears again, replace the seat assembly. Ref. to SEATS>FRONT SEAT
0029H	Sensor malfunction	Rezeroing cannot be performed due to sensor malfunction during rezeroing.	Read [Airbag] DTCs, and perform the diagnosis for the displayed DTCs. Ref. to AIRBAG (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)
0030H	Memory access error	Rezeroing cannot be performed due to data flash malfunction during rezeroing.	Read [Airbag] DTCs, and perform the diagnosis for the displayed DTCs. Ref. to AIRBAG (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC)
