ODS Unit Initialization
NOTE:
- After SRS unit for ODS unit is replaced, do this procedure to initialize the ODS unit.
- ODS unit initialization will initialize both OPDS sensor and seat weight sensor.
OPDS Sensor Initialization With the HDS
After a seat-back cover, seat-back cushion, and/or ODS unit is replaced, do this procedure to initialize the OPDS sensor with the HDS unit.
NOTE:
- A new (uninitialized) ODS unit installed with a faulty OPDS sensor can cause DTC 85-71 and DTC 85-78.
- Before initializing the ODS unit, make sure the battery is fully charged.
1. Clear the DTC memory. Reading and Clearing Diagnostic Trouble Codes
2. Make sure the front passenger's seat is dry. Set the seat-back in a normal position, and make sure there is nothing on the seat.
3. Make sure the ignition switch is in LOCK (0).
4. Connect the HDS to the data link connector (DLC) (A).
5. Turn the ignition switch to ON (II).
6. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit:
- R18A1 engine Testing and Inspection
- K20Z3 engine Testing and Inspection
7. From the HDS Main Menu, select SRS, then INITIALIZATION. In the INITIALIZATION Menu, select OPDS Initialization. Follow the prompts until the OPDS sensor initialization has been completed.
8. Turn the ignition switch to LOCK (0).
9. Disconnect the HDS from the DLC.
NOTE: If the ODS unit fails to initialize after several attempts, replace the seat-back with equipped OPDS sensor Front Seat-Back Cover Replacement, and retry. If the ODS unit continues to fail to initialize, replace the ODS unit. ODS Unit Replacement
OPDS Sensor Initialization Without the HDS
Special Tools Required
- SCS service connector 07PAZ-001010A
1. Adjust the front passenger's seat-back to a normal upright position, and remove anything that is on or near the seat.
2. Turn the ignition switch to LOCK (0).
3. Connect the HDS to the data link connector (DLC).
4. If not already connected the HDS to the DLC, then turn on the HDS, but do not turn the ignition switch to ON (II).
5. From the Select Mode screen, select SCS, and follow the screen prompts.
6. Make sure the ignition switch is in LOCK (0).
7. Connect the SCS service connector (A) to the yellow MES 2P connector (B). Do not use a jumper wire.
8. Turn the ignition switch to ON (II).
9. The SRS indicator will come on for about 6 seconds, and then go off. Unplug the SCS service connector from the MES 2P connector within 4 seconds after the indicator goes off.
10. The SRS indicator will come on again, plug the SCS service connector to the MES 2P connector within 4 seconds after the indicator comes on.
11. When the SRS indicator goes off, unplug the SCS service connector from the MES 2P connector within 4 seconds.
12. Watch the SRS indicator:
- If the indicator blinks twice and then goes off, the ODS unit is initialized. Turn the ignition switch to LOCK (0), and disconnect the HDS. Return the vehicle to your customer.
- If the indicator blinks twice and then stays on, the ODS unit is initialized, but the SRS DTCs need to be cleared. Clear the DTC memory. Reading and Clearing Diagnostic Trouble Codes
- If the indicator stays on without first blinking, the ODS unit is not initialized. Repeat step 3 thru 11.
Front Passenger's Weight Sensor Initialization With the HDS
When you replace the SRS unit, the front passenger's seat assembly, or the ODS unit, initialize the front passenger's weight sensor with the HDS unit.
While doing the ODS unit, observe these precautions:
- Make sure all components of the front passenger's seat are correctly installed.
- Make sure nothing is on the front passenger's seat.
- Make sure there is nothing in the front passenger's seat-back pocket.
- Keep the windows and the moonroof closed.
- Do all initialization procedures, except test-driving, in the service bay.
- Make sure the vehicle is on level ground.
- Keep the A/C and the heater off.
- Do not touch the front passenger's seat during initialization, until you are prompted to or when you have completed the initialization.
- Do not expose the front passenger's seat to sudden temperature changes.
1. Position the front passenger's seat all the way rearward, and adjust the seat-back to the forward most position. Do not move the seat from this position until the initialization is completed.
2. Make sure the ignition switch is in LOCK (0).
3. Connect the HDS to the data link connector (DLC) (A).
4. Turn the ignition switch to ON (II).
5. Make sure the HDS communicates with the vehicle and the SRS unit. If it does not communicate, troubleshoot the DLC circuit:
- R18A1 engine Testing and Inspection
- K20Z3 engine Testing and Inspection
6. Drive the vehicle, and accelerate to 20 mph (36 km/h), then stop on level ground.
7. From the HDS Main Menu, select SRS, then INITIALIZATION. In the INITIALIZATION Menu, select SWS Initialization. Follow the prompts until the front passenger's weight sensor initialization has been completed.
8. Turn the ignition switch to LOCK (0).
9. Disconnect the HDS from the DLC.
Front Passenger's Weight Sensor Initialization Without the HDS
Special Tools Required
- SCS service connector 07PAZ-001010A
When you replace the SRS unit, the front passenger's weight sensors, or the ODS unit, calibrate the ODS unit.
While doing the ODS unit, observe these precautions:
- Make sure all components of the front passenger's seat are correctly installed.
- Make sure nothing is on the passenger's seat.
- Make sure nothing is on the passenger's seat-back pocket.
- Keep the windows and the moonroof closed.
- Perform all initialization procedures except, test driver's, in the service bay.
- Make sure the vehicle is on level ground.
- Keep the A/C and the heater off.
- Do not touch the front passenger's seat until you driver's the vehicle.
- Do not expose the front passenger's seat to sudden temperature changes.
1. Adjust the front passenger's seat-back to a normal upright position, and remove anything that is on or near the seat.
2. Turn the ignition switch to LOCK (0).
3. Connect the HDS to the data link connector (DLC).
4. If not already connected the HDS to the DLC, then turn on the HDS, but do not turn the ignition switch to ON (II).
5. From the Select Mode screen, select SCS, and follow the screen prompts.
6. Make sure the ignition switch is in LOCK (0).
7. Connect the SCS service connector (A) to the yellow MES 2P connector (B). Do not use a jumper wire.
8. Turn the ignition switch to ON (II).
9. The SRS indicator will come on for about 6 seconds, and then go off. Put off the seat belt buckle within 4 seconds after the indicator goes off.
10. The SRS indicator will come on again. Put on the seat belt buckle within 4 seconds after the indicator comes on.
11. When the SRS indicator goes off, Put off the seat belt buckle within 4 seconds after the indicator comes on.
12. Watch the SRS indicator:
- If the indicator blinks twice and then goes off, the ODS unit is initialized. Turn the ignition switch to LOCK (0), and disconnect the HDS. Return the vehicle to your customer.
- If the indicator blinks twice and then stays on, the ODS unit is initialized, but the SRS DTCs need to be cleared. Go to clear the DTC memory. Reading and Clearing Diagnostic Trouble Codes
- If the indicator stays on without first blinking, the ODS unit is not initialized. Repeat step 3 thru 11.
