System Reset - Bladder OCS
WARNING: This page is about a different car, the 2015 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
Make sure the front passenger seat repair is complete, the seat and all attached components (head restraint, seat side shield, etc.) are correctly assembled, and the seat is correctly installed to the vehicle before using System Reset to rezero the seat weight. Failure to follow these instructions may result in incorrect operation of the occupant classification system (OCS) and increases the risk of serious personal injury or death in a crash.
NOTE:
To prevent system failure, it is necessary to carry out the OCS reset when a front passenger seat cushion is disassembled, a new cover installed or an OCS service kit is installed. A scan tool is used to carry out the OCS reset.
NOTE:
To prevent system failure, the following precautions must be taken before carrying out the OCS reset:
- Make sure the voltage to the OCSM is above 8 volts and less than 18 volts.
- Make sure the OCS is not at a temperature below 6°C (42°F) or above 36°C (97°F) when initiating the OCS reset. If the vehicle has been exposed to extreme cold or hot temperatures, the vehicle must be exposed to and kept at a temperature within the limits, 6°C to 36°C (42°F to 97°F) for a minimum of 30 minutes.
- Make sure nothing is present on the passenger seat before carrying out the OCS reset and nothing is placed on the seat during the process.
- Make sure a minimum 8-second time period has passed after cycling the ignition ON before carrying out the OCS reset.
NOTE:
The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- 1.
Make sure no OCSM DTCs are present. If DTC U3000:54 is the only OCSM present, it will clear upon completion of a successful system reset. All other OCSM DTCs must be diagnosed and repaired before carrying out the OCS reset.
- 3.
If the first system reset attempt was unsuccessful, carry out a thorough inspection of the following and repair any concerns found.- Check the OCS connector and wiring for damage.
- Inspect the pressure sensor hose for kinks and/or damage.
- Verify correct pressure sensor hose routing -. Refer to Occupant Classification Sensor .
- Inspect seat-related wiring harness and body wiring harness terminals and connectors for damage.
- 4.
Carry out a second OCS reset. If unsuccessful, install a new OCS service kit. Refer to Occupant Classification Sensor .
- 5.
Prove out the SRS as follows:With the ignition OFF, wait 10 seconds, then turn the ignition ON and monitor the air bag warning indicator with the air bag modules installed. The air bag warning indicator illuminates continuously for approximately 6 seconds and then turns off. If a SRS fault is present, the air bag warning indicator will:- fail to light.- remain lit continuously.- flash. The flashing might not occur until approximately 30 seconds after the ignition has been turned from OFF to ON. This is the time required to complete testing of the SRS. If the air bag warning indicator is inoperative and a SRS fault exists, a chime sounds in a pattern of 5 sets of 5 beeps. If this occurs, diagnose and repair the air bag warning indicator and any SRS faults.
