WARNING:
The following precautions must be taken before carrying out the following procedure on the front passenger seat:
- Park the vehicle on level ground.
- Make sure the occupant classification sensor (OCS) system is stabilized at a temperature in the range of 5°C to 48°C (41°F to 118°F) and is not exposed to temperatures outside that range.
- Make sure the front passenger seat is empty and dry.
- Make sure the front passenger seat repair is complete and all attached components (head restraint, seat side shield) are correctly installed.
- Make sure nothing is placed in the map pockets (if equipped) of the front passenger seat.
- Make sure nothing is underneath the front passenger seat.
- Make sure no non-factory installed items (seat covers, DVD screens) are on or contacting the front passenger seat. If any non-factory items were installed to the seat, remove the item(s) and communicate to the customer that any alteration/modification to the front passenger seat may affect performance of the OCS system. Refer to the Owner's Literature .
- Make sure the seat is correctly installed in the vehicle.
Failure to follow these instructions may result in incorrect operation of the OCS system and increases the risk of serious personal injury or death in a crash.
NOTE:
After installation of new OCS
system component(s) and the completion of INSPECTION AND REPAIR AFTER A SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPLOYMENT , the OCSM
will have DTC B1193:00 stored in memory. In the event of a crash, DTC B1193:00 must be cleared before carrying out the Occupant Classification Sensor (OCS) System Reset.
- If a SRS
deployment has occurred, carry out the following steps:
- Verify that all steps have been carried out as outlined in the Inspection and Repair After a Supplemental Restraint System (SRS) Deployment procedure .
-
NOTE: A new RCM must be installed before clearing OCSM DTC B1193:00, if a new RCM is not installed first, the OCSM DTC B1193:00 will not clear.
Clear OCSM DTC B1193:00.
- Proceed to Step 4 to carry out the System Reset.
- If SRS
deployment has NOT
occurred, if the front passenger seat has been removed and/or serviced or new OCS
components have been installed, proceed to Step 3 to carry out the System Reset. NOTE: After installation of new OCS system component(s), (seat track assembly or OCSM ), the OCSM will have DTC B00A0:54 stored in memory. This DTC will clear after a successful System Reset.
- Carry out the RCM
self-test. If DTC B00A0:09 is retrieved on-demand, retrieve OCSM
DTCs.
- If OCSM DTCs are retrieved on-demand and NO new components have been installed, refer to the OCSM DTC CHART for diagnostic direction.
- If no OCSM DTCs are retrieved on-demand, CLEAR the DTC from the RCM and proceed to step 4 to carry out the System Reset
- Turn the ignition to the OFF position.
- Prepare the passenger seat for a System Reset and make sure:
- the OCS weight sensor bolt harness connections are correct for each sensor at the correct locations. Refer to appropriate SYSTEM WIRING DIAGRAMS article, Supplemental Restraint System for schematic and connector information. Refer to the illustration for correct sensor location on the seat.
- the seat wiring harnesses are routed and secured correctly and are not twisted, pinched, pulling down or pushing up on any seat component.
- all seat fasteners have been tightened to specification as identified in the appropriate Service Information article . Refer to SPECIFICATIONS .
- make sure the seat track and backrest frame are not bent, twisted or damaged.
- move the seat and backrest to all seating positions. Make sure the seat track does not bind or have any resistance when moved to all seating positions. Make sure that there are no obstructions contacting any seat component when the seat is moved to all seating positions.
- the seat is correctly installed in the vehicle.
- the passenger safety belt buckle is unbuckled .
- the front passenger seat is empty and there is nothing underneath the seat. Remove any items that were not factory components installed and make sure that the seat is correctly installed in the vehicle
- the seat backrest is in a normal seating (vertical) position.
- the seat is at the mid-point of seat track travel.
- the hysteresis has been removed from the front passenger seat by firmly hitting the seat backrest 3 times.
- the vehicle electrical system voltage is below 18 volts and above 11.5 volts before continuing with the OCS System Reset.
- Turn the ignition ON, wait 8 seconds.
- Carry out the OCSM
System Reset.
- If the System Reset was successful, carry out the OCS Zero Seat Weight Test. For additional information, refer to OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM ZERO SEAT WEIGHT TEST .
- If the System Reset was unsuccessful, proceed to step 8 .
-
NOTE: Do not install any new OCS system components at this time. OCS system components should only be installed when directed to do so.
Retrieve OCSM DTCs.
- If DTC B00A0:54 is retrieved on-demand, refer to the DTC CHARTS for diagnostic direction of this DTC.
- If any other DTCs are retrieved on-demand from the OCSM , proceed to Step 9 .
- Inspect all the items listed in Step 5 for causes of a unsuccessful System Reset, repair as necessary. Retest the system.
- If the System Reset was successful, carry out the OCCUPANT CLASSIFICATION SENSOR (OCS) SYSTEM ZERO SEAT WEIGHT TEST .
If the System Reset was unsuccessful, install OCS weight sensor assemblies, refer to OCCUPANT CLASSIFICATION SENSOR .
