Section 41 (Occupant Detection System (Diagnostics)): Rezero: List

WARNING: This page is about a different car, the 2021 Subaru Ascent. 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	Occupant detection 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 the DTC of [Occupant Detection] Ref. to OCCUPANT DETECTION (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) ., and perform the diagnosis for the displayed DTCs. Ref. to OCCUPANT DETECTION (DIAGNOSTICS)>Diagnostic Trouble Code (DTC)>LIST .
0030H	Memory access error	Rezeroing cannot be performed due to data flash malfunction during rezeroing.	Read the DTC of [Occupant Detection] Ref. to OCCUPANT DETECTION (DIAGNOSTICS)>Diagnostic Trouble Code (DTC) ., and perform the diagnosis for the displayed DTCs.
