INTRODUCTION
This bulletin provides clearer steps for completing the Occupant Detection System (ODS) rezeroing (system calibration) procedure along with a revised diagnostic chart for DTC B1650 (ODS Failure).
NOTE: Although the Service Manual uses these terms interchangeably throughout ODS diagnosis, the meaning of the terms “rezeroing”, “rezero” or “system calibration” is all the same.
SERVICE PROCEDURE / INFORMATION
12. System Calibration (Rezeroing)
A: OPERATION
IMPORTANT: When replacing the ODS, or removing and disassembling the passenger’s seat for any reason, (this includes, but is not limited to seat cover replacement), the rezeroing procedure must ALWAYS be performed after reinstalling the seat in the vehicle. The rezeroing procedure is not a “Stand Alone” operation.
Confirm no aftermarket devices are connected to the vehicle. If the DTC is a result of the presence of an aftermarket device, advise the customer to remove the device from the vehicle to avoid possible interference with the ODS function.
[VEHICLE PREPARATION]
- Park empty vehicle on a level surface.
- Check that seat temperature is in a range from 0 to 40°C (32 to 104°F).
- Remove any weighty objects from the vehicle.
- Check and adjust the following items on the vehicle:
- Verify that all ODS-related harnesses and connectors are fully seated.
- Verify that the seat assembly is correctly installed in the vehicle.
- Adjust the seat backrest to be fully upright.
- Adjust the seat slide position all the way back.
- Sit on the seat cushion to smooth the seat surface.
- Exit the seat.
- Do not place anything on the top of the seat cushion.
- Check that the passenger’s seat belt is NOT inserted into the buckle and is fully retracted.
NOTE: If the vehicle has been parked outside in temperatures outside the 0° to 40° C (32°-104° F) range, bring the vehicle into an area within this temperature range, lower all windows and allow temperature to stabilize. The rezeroing procedure will not be successful if the ODS system is outside of this range during calibration.
- Connect the SSMIII and turn the ignition switch ON.
- On «Main Menu» display, select {Each System Check}.
- On «System Selection Menu» display, select {Air Bag System}.
- On the {Air Bag System} display, select {Diagnostic Code(s) Display}.
- Make sure that none of the following DTCs are current or in memory:
2010 to 2012MY: 27, 29, 2A, 2C, 37 2013 to 2014MY: B1650, B1655, B16EE, B16EF
If any of these DTCs are current or in memory, read the DTC of the airbag system, and perform the diagnosis while referring to List of Diagnostic Trouble Code (DTC) in the applicable Service Manual.
- On «Main Menu» display, select {Each System Check}.
- On «System Selection Menu» display, select {Occupant Detection System}.
- On the {Occupant Detection System} display, select {Rezeroing}.
NOTE: DO NOT TOUCH THE PASSENGER SEAT OR ROCK THE VEHICLE until the rezeroing
procedure is completed. If you have touched the seat, even if only once, re-perform the steps from the beginning.
- Follow to SSMIII screen to perform the rezeroing procedure.
NOTE: When the «Re-zeroing Empty the passenger seat» is displayed, make sure that the passenger’s seat is empty and airbag “OFF” indicator is illuminated. After verifying the condition, TURN IGNITION OFF and, within 10 seconds, TURN IGNITION ON again, then select [OK].
- When the rezeroing procedure completes normally, the «Re-zeroing is successfully completed» is displayed. Turn the ignition switch to OFF to finish the rezeroing procedure.
- During the rezeroing procedure, if «Rezeroing is unsuccessful, See service manual» is displayed, Press ”OK”, and turn the ignition switch to OFF once and wait for a while. Please repeat the procedure from step 1), making sure to follow each step carefully.
NOTE: There is no limit to the number of rezeroing attempts. If rezeroing is unsuccessful, there is a possibility that the procedure was not completed correctly.
REMINDER: If are any current or stored DTCs in the ODS system, the rezeroing procedure will NOT be successful. Repair any faults following the procedures outlined in the applicable Service Manual then perform the rezeroing procedure.

NOTE: For sedan models, connect test harness AH between the connectors (AB6, AB17, AB18) and (1AG). 5) Connect the connector (1AD) in the test harness AD to the connector (AB53). 6) Measure the resistance between connector (6AG) or (5AG) in the test harness AG and connector (2AD) in the test harness AD. Connector & terminal Sedan model (5AG) No. 3 — (2AD) No. 2: (5AG) No. 8 — (2AD) No. 3: OUTBACK model (6AG) No. 10 — (2AD) No. 3: (6AG) No. 12 — (2AD) No. 2: Is the resistance less than 10Ω? Go to step 5. Replace the airbag rear harness along with body harness. 5 CHECK AIRBAG REAR HARNESS. Measure the resistance between connector (2AD) in the test harness AD and chassis ground, and between connector (2AD) terminals. Connector & terminal (2AD) No. 2 — chassis ground: (2AD) No. 3 — chassis ground: (2AD) No. 2 — (2AD) No. 3: Is the resistance 1 MΩ or more? Go to step 6.

Connector & terminal (2AD) No. 1 (+) — Chassis ground (–): Is the voltage 10 V or more? Replace the occupant detection harness (seat harness). If defective is not improved, replace the occupant detection system (seat cushion & frame assembly), and then the airbag control module in this order. <Ref. to SE-27, PASSENGER’S SEAT, DISASSEMBLY, Front Seat.> Check the battery voltage and fuse. If there is no fault, replace the airbag rear harness together with body harness.
